Android棉花糖请求许可？

Question

我目前正在开发一个需要多个 "dangerous" 权限的应用程序。所以我尝试根据 Android Marshmallow（API 级别 23）中的要求添加 "ask for permission"，但找不到如何做。

如何在我的应用程序中使用新的权限模型请求权限？

Answer 1

Android-M 即 API 23 引入了 Runtime Permissions 以减少 android 设备中的安全漏洞，用户现在可以在 [=26] 直接管理应用权限=] 如果用户拒绝您的应用程序的特定权限，您必须通过询问您在查询中提到的权限对话框来获得它。

所以在操作之前检查一下，即检查您是否有权访问资源 link and if your application doesn't have that particular permission you can request the permission link 并像下面那样处理权限请求响应。

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.

               } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

最后，如果您打算使用新版本以避免强制关闭，那么完成 behavior changes 是一个很好的做法:)

Answer 2

使用以下代码打开对话框：

 ActivityCompat.requestPermissions(MainActivity.this,
                    new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                    1);

得到Activity结果如下：

@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case 1: {

          // If request is cancelled, the result arrays are empty.
          if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.          
            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
                Toast.makeText(MainActivity.this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show();
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

Answer 3

我使用了 google 开发人员编写的这个包装器（推荐）。超级好用。

https://github.com/googlesamples/easypermissions

函数处理检查并在需要时请求许可

public void locationAndContactsTask() {
    String[] perms = { Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.READ_CONTACTS };
    if (EasyPermissions.hasPermissions(this, perms)) {
        // Have permissions, do the thing!
        Toast.makeText(this, "TODO: Location and Contacts things", Toast.LENGTH_LONG).show();
    } else {
        // Ask for both permissions
        EasyPermissions.requestPermissions(this, getString(R.string.rationale_location_contacts),
                RC_LOCATION_CONTACTS_PERM, perms);
    }
}

编码愉快:)

Answer 4

我将其用作基础片段 class。我只请求一个片段的权限，但你可以重构它并制作一个类似的 Activity 版本。

public class BaseFragment extends Fragment {

    private static final int PERMISSION_REQUEST_BLOCK_INTERNAL = 555;
    private static final String PERMISSION_SHARED_PREFERENCES = "permissions";

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == PERMISSION_REQUEST_BLOCK_INTERNAL) {
            boolean allPermissionsGranted = true;

            for (int iGranting : grantResults) {
                if (iGranting != PermissionChecker.PERMISSION_GRANTED) {
                    allPermissionsGranted = false;
                    break;
                }
            }

            if (allPermissionsGranted && permissionBlock != null) {
                permissionBlock.run();
            }

            permissionBlock = null;
        }
    }

    public void runNowOrAskForPermissionsFirst(String permission, Runnable block) {
        if (hasPermission(permission)) {
            block.run();
        } else if (!hasPermissionOrWillAsk(permission)) {
            permissionBlock = block;
            askForPermission(permission, PERMISSION_REQUEST_BLOCK_INTERNAL);
        }
    }

    public boolean hasPermissionOrWillAsk(String permission) {
        boolean hasPermission = hasPermission(permission);
        boolean hasAsked = hasPreviouslyAskedForPermission(permission);
        boolean shouldExplain = shouldShowRequestPermissionRationale(permission);

        return hasPermission || (hasAsked && !shouldExplain);
    }

    private boolean hasPermission(String permission) {
        return (ContextCompat.checkSelfPermission(getContext(), permission) == PackageManager.PERMISSION_GRANTED);
    }

    private boolean hasPreviouslyAskedForPermission(String permission) {
        SharedPreferences prefs = getContext().getSharedPreferences(PERMISSION_SHARED_PREFERENCES, Context.MODE_PRIVATE);
        return prefs.getBoolean(permission, false);
    }

    private void askForPermission(String permission, int requestCode) {
        SharedPreferences.Editor editor = getContext().getSharedPreferences(PERMISSION_SHARED_PREFERENCES, Context.MODE_PRIVATE).edit();

        editor.putBoolean(permission, true);
        editor.apply();

        requestPermissions(new String[] { permission }, requestCode);
    }
}

您应该使用两种关键方法：

hasPermissionOrWillAsk - 使用它来查看是否已请求权限并拒绝不想再次请求的用户。当用户给出关于不想要某个功能的最终答案时，这对于禁用 UI 很有用。
运行NowOrAskForPermissionsFirst - 使用它来运行一些需要权限的代码。如果用户已经授予权限，代码将立即运行。否则，如果用户授予权限，代码将稍后运行。或者根本没有。这很好，因为您可以在一个地方指定代码。

这是一个例子：

mFragment.runNowOrAskForPermissionsFirst(Manifest.permission.ACCESS_FINE_LOCATION, new Runnable() {
    @Override
    public void run() {
        ...do something if we have permission...
    }
});

很高兴收到对此的反馈。并不是说这个特定示例有点简化，因为您还需要检查设备上是否启用了定位服务。（这与权限不同。）此外，它一次只支持一个权限，但如果您需要它一次支持多个权限，修改起来很简单。

Answer 5

我使用这个结构来检查我的应用程序是否有权限，而不是请求它是否没有权限。所以在我要检查的主要代码中写入以下内容：

int MyVersion = Build.VERSION.SDK_INT;
if (MyVersion > Build.VERSION_CODES.LOLLIPOP_MR1) {
                if (!checkIfAlreadyhavePermission()) {
                    requestForSpecificPermission();
                }
}

模块 checkIfAlreadyhavePermission() 实现为：

private boolean checkIfAlreadyhavePermission() {
    int result = ContextCompat.checkSelfPermission(this, Manifest.permission.GET_ACCOUNTS);
    if (result == PackageManager.PERMISSION_GRANTED) {
        return true;
    } else {
        return false;
    }
}

模块 requestForSpecificPermission() 实现为：

private void requestForSpecificPermission() {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.GET_ACCOUNTS, Manifest.permission.RECEIVE_SMS, Manifest.permission.READ_SMS, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, 101);
}

并在 Activity 中覆盖：

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case 101:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //granted
            } else {
                //not granted
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

Answer 6

一次获得多个权限，您可以使用它。这对我有用..我得到了另一个解决方案。如果你给你的 targetSdkVersion 低于 22 它对我有用。它的行为就像从 manifest.xml 获得许可一样。经过测试并为我工作。

final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;

    private void insertDummyContactWrapper() {
        List<String> permissionsNeeded = new ArrayList<String>();

        final List<String> permissionsList = new ArrayList<String>();
        if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
            permissionsNeeded.add("GPS");
        if (!addPermission(permissionsList, Manifest.permission.READ_CONTACTS))
            permissionsNeeded.add("Read Contacts");
        if (!addPermission(permissionsList, Manifest.permission.WRITE_CONTACTS))
            permissionsNeeded.add("Write Contacts");

        if (permissionsList.size() > 0) {
            if (permissionsNeeded.size() > 0) {
                // Need Rationale
                String message = "You need to grant access to " + permissionsNeeded.get(0);
                for (int i = 1; i < permissionsNeeded.size(); i++)
                    message = message + ", " + permissionsNeeded.get(i);
                showMessageOKCancel(message,
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                                        REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);

            // Check for Rationale Option
            if (!shouldShowRequestPermissionRationale(permission))
                return false;

Answer 7

从 Android Marshmallow 开始，我们需要向用户请求特定权限。我们还可以通过代码检查是否已授予权限。以下是常用权限的列表：

android.permission_group.CALENDAR

android.permission.READ_CALENDAR

android.permission.WRITE_CALENDAR

android.permission_group.CAMERA

android.permission.CAMERA

android.permission_group.CONTACTS

android.permission.READ_CONTACTS

android.permission.WRITE_CONTACTS

android.permission.GET_ACCOUNTS

android.permission_group.LOCATION

android.permission.ACCESS_FINE_LOCATION

android.permission.ACCESS_COARSE_LOCATION

android.permission_group.MICROPHONE

android.permission.RECORD_AUDIO

android.permission_group.PHONE

android.permission.READ_PHONE_STATE

android.permission.CALL_PHONE

android.permission.READ_CALL_LOG

android.permission.WRITE_CALL_LOG

android.permission.ADD_VOICEMAIL

android.permission.USE_SIP

android.permission.PROCESS_OUTGOING_CALLS

android.permission_group.SENSORS

android.permission.BODY_SENSORS

android.permission_group.SMS

android.permission.SEND_SMS

android.permission.RECEIVE_SMS

android.permission.READ_SMS

android.permission.RECEIVE_WAP_PUSH

android.permission.RECEIVE_MMS

android.permission.READ_CELL_BROADCASTS

android.permission_group.STORAGE

android.permission.READ_EXTERNAL_STORAGE

android.permission.WRITE_EXTERNAL_STORAGE

这是检查权限的示例代码：

if (ContextCompat.checkSelfPermission(context, Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
    if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, Manifest.permission.WRITE_CALENDAR)) {
        AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
        alertBuilder.setCancelable(true);
        alertBuilder.setMessage("Write calendar permission is necessary to write event!!!");
        alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
            public void onClick(DialogInterface dialog, int which) {
                ActivityCompat.requestPermissions((Activity)context, new String[]{Manifest.permission.WRITE_CALENDAR}, MY_PERMISSIONS_REQUEST_WRITE_CALENDAR);
            }
        });
    } else {
        ActivityCompat.requestPermissions((Activity)context, new String[]{Manifest.permission.WRITE_CALENDAR}, MY_PERMISSIONS_REQUEST_WRITE_CALENDAR);
    }
}

Answer 8

有一个很好的库，可以在后台服务需要权限时需要请求权限的情况下使用。尽管库的局限性在于它不能仅用于确定当前是否已授予应用程序权限。它总是询问用户应用是否还没有它们。

一定要试一试，因为它会让生活变得更简单：Android Permissions

Answer 9

处理运行时权限google 提供了一个库项目。您可以从这里查看 https://github.com/googlesamples/easypermissions

EasyPermissions 通过将以下依赖项添加到您的 build.gradle 文件来安装：

dependencies {
compile 'pub.devrel:easypermissions:0.3.0'
}

要开始使用 EasyPermissions，让您的 Activity（或 Fragment）覆盖 onRequestPermissionsResult 方法：

public class MainActivity extends AppCompatActivity implements EasyPermissions.PermissionCallbacks {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    // Forward results to EasyPermissions
    EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
}

@Override
public void onPermissionsGranted(int requestCode, List<String> list) {
    // Some permissions have been granted
    // ...
}

@Override
public void onPermissionsDenied(int requestCode, List<String> list) {
    // Some permissions have been denied
    // ...
}
}

在这里你会得到一个工作示例这个库是如何工作的 https://github.com/milon87/EasyPermission

Answer 10

这可能是一种更简洁的方式。将所有权限添加到数组中，例如

private static final String[] INITIAL_PERMS={
            android.Manifest.permission.ACCESS_FINE_LOCATION,
            android.Manifest.permission.ACCESS_COARSE_LOCATION
    };
    private static final int INITIAL_REQUEST=1337;

无论您的权限是什么，为每个权限创建方法

@RequiresApi(api = Build.VERSION_CODES.M)
private boolean canAccessFineLocation() {
    return(hasPermission(Manifest.permission.ACCESS_FINE_LOCATION));
}

@RequiresApi(api = Build.VERSION_CODES.M)
private boolean canAccessCoarseLocation() {
    return(hasPermission(Manifest.permission.ACCESS_COARSE_LOCATION));
}

@RequiresApi(api = Build.VERSION_CODES.M)
private boolean hasPermission(String perm) {
    return(PackageManager.PERMISSION_GRANTED == checkSelfPermission(perm));
}

在onCreate

中调用此方法

 if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
      if(!canAccessCoarseLocation() || !canAccessFineLocation()){
            requestPermissions(INITIAL_PERMS, INITIAL_REQUEST);
        }
 }

现在覆盖 onRequestPermissionsResult

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    if(requestCode == INITIAL_REQUEST){
        if (canAccessFineLocation() && canAccessCoarseLocation())  {
            //call your method
        }
        else {
            //show Toast or alert that this permissions is neccessary
        }
    }
}

Answer 11

从 Android Marshmallow(API 23) 及更高版本默认禁用所有危险权限（根据官方文档 official doc）。安装后，当应用程序首次打开时，您必须在运行时间授予权限。

我是通过以下方式实现的：

public class MarshMallowPermission {

    public static final int EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE_BY_GALLERY = 0;
    public static final int EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE_BY_CAMERA = 1;
    public static final int EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE_BY_LOAD_PROFILE = 2;
    public static final int CAMERA_PERMISSION_REQUEST_CODE = 3;
    public static final int LOCATION_PERMISSION_REQUEST_CODE = 4;
    Activity activity;
    Context mContext;

    public MarshMallowPermission(Activity activity) {
        this.activity = activity;
        this.mContext = activity;
    }

    public boolean checkPermissionForExternalStorage(){
        int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if (result == PackageManager.PERMISSION_GRANTED){
            return true;
        } else {
            return false;
        }
    }

    public boolean checkPermissionForCamera(){
        int result = ContextCompat.checkSelfPermission(activity, Manifest.permission.CAMERA);
        if (result == PackageManager.PERMISSION_GRANTED){
            return true;
        } else {
            return false;
        }
    }

    public boolean checkLocationPermission(){

        int result = ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION);
        if (result == PackageManager.PERMISSION_GRANTED){
            return true;
        } else {
            return false;
        }
    }

    public void requestPermissionForExternalStorage(int requestCode){
        if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE)){
            Toast.makeText(mContext.getApplicationContext(), "External Storage permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
        } else {
            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},requestCode);
        }
    }

    public void requestPermissionForCamera(){
        if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.CAMERA)){
            Toast.makeText(mContext.getApplicationContext(), "Camera permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
        } else {
            ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.CAMERA},CAMERA_PERMISSION_REQUEST_CODE);
        }
    }
    public void requestPermissionForLocation(){
        if (ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.ACCESS_FINE_LOCATION) && ActivityCompat.shouldShowRequestPermissionRationale(activity, Manifest.permission.ACCESS_COARSE_LOCATION)){
            Toast.makeText(mContext.getApplicationContext(), "Location permission needed. Please allow in App Settings for additional functionality.", Toast.LENGTH_LONG).show();
        } else {
            ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION}, LOCATION_PERMISSION_REQUEST_CODE);
        }
    }
}

在你的 activity class:

 public class MainActivity extends AppCompatActivity{

   private MarshMallowPermission marshMallowPermission;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d("NavHome", "Oncreate_nav");
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        marshMallowPermission = new MarshMallowPermission(MainActivity.this);



        if (!marshMallowPermission.checkPermissionForExternalStorage()) {
            marshMallowPermission.requestPermissionForExternalStorage(MarshMallowPermission.EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE_BY_LOAD_PROFILE);
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        switch (requestCode) {
            case MarshMallowPermission.EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE_BY_LOAD_PROFILE:
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                    //permission granted successfully

                } else {

                 //permission denied

                }
                break;
    }

我的 class 在 Activity 或 Fragment

它还可以帮助您显示 基本原理 或打开设置以在用户拒绝权限后启用权限（with/without Never ask again) 选项更简单

试试这个

这是 Marshmallow 版本中请求权限的最简单方法。

 if (ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED&&ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED)
    {
        //TO do here if permission is granted by user
    }
    else
    {
        //ask for permission if user didnot given
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
        {
            requestPermissions(new String[]{Manifest.permission.CAMERA,Manifest.permission.ACCESS_FINE_LOCATION}, 0);
        }
    }

注意：-不要忘记在清单文件中也添加同样的权限

 <uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

第二种方法 权限检查代码是否授予？

ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CAMERA}, 1);

并覆盖方法

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case 1: {
            if (grantResults.length > 0 && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
         //                    grantResult[0] means it will check for the first postion permission which is READ_EXTERNAL_STORAGE
        //                    grantResult[1] means it will check for the Second postion permission which is CAMERA
                Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show();
            }
            else
                Toast.makeText(this, "Permission not Granted", Toast.LENGTH_SHORT).show();
            return;
        }
    }
}

Answer 15

您可以使用我的图书馆 — NoPermission（只有一个 class）

compile 'ru.alexbykov:nopermission:1.1.1'

样本

PermissionHelper permissionHelper = new PermissionHelper(this); //don't use getActivity in fragment!

permissionHelper.check(Manifest.permission.READ_CONTACTS)
                .onSuccess(this::onSuccess)
                .onDenied(this::onDenied)
                .onNeverAskAgain(this::onNeverAskAgain)
                .run();

onRequestPermissionResult:

 @Override
  public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
        permissionHelper.onRequestPermissionsResult(requestCode, permissions, grantResults);
   }

我认为 api 比 EasyPermissions 方便 Google。

Answer 16

下面的代码有效perfectly.I我正在借助示例进行解释。

在我的例子中，我将权限检查单独放在一个 util class 中，并传递了我需要从适当的 classes.This 检查的特定权限，以便在整个过程中重用权限检查 util 文件申请。

下面的代码部分显示了函数 call.In 这种情况正在请求 android.Manifest.permission.READ_EXTERNAL_STORAGE 权限。

//the below call is from a fragment
     @OnClick(R.id.button)//butterknife implementation
        public void attachPressed() {
            if (PermissionUtils.hasThisPermission(getContext(), android.Manifest.permission.READ_EXTERNAL_STORAGE)) {
                onAttachPressed();
            } else {
                PermissionUtils.isPermissionRequestNeeded(getActivity(), this, android.Manifest.permission.READ_EXTERNAL_STORAGE, PermissionUtils.REQUEST_GROUP_STORAGE);
            }
        }

在上述情况下，检查权限是否被允许调用 onAttachPressed(); 函数，否则我们检查请求权限。

以下是 util class 中的代码 PermissionUtils

public final class PermissionUtils {

    public static final int REQUEST_GROUP_STORAGE = 1508;

    private PermissionUtils() {
    }

    public static boolean hasThisPermission(Context context, String permission) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            return ActivityCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED;
        } else {
            return true;
        }
    }

    public static boolean isPermissionRequestNeeded(Activity activity, Fragment fragment, String permission, int requestCode) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !hasThisPermission(activity, permission)) {
            final String[] permissions = new String[]{permission};
            if (fragment == null) {
                activity.requestPermissions(permissions, requestCode);
            } else {
                fragment.requestPermissions(permissions, requestCode);
            }
            return true;
        }
        return false;
    }
}

在请求之后，如果您可能想从 onRequestPermissionsResult 调用该函数，否则您将需要再次按下按钮以进行函数调用。

所以只需从 onRequestPermissionsResult

调用它

//the below call  is from a fragment
     @Override
        public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
            if (requestCode == PermissionUtils.REQUEST_GROUP_STORAGE && grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                onAttachPressed();
            } else {
                Log.e("value", "Permission Denied, You cannot use local drive .");
            }
        }

通过避免编写大量代码来请求许可的简单方法，

https://github.com/sachinvarma/EasyPermission

如何添加：

repositories {
        maven { url "https://jitpack.io" }
    }

implementation 'com.github.sachinvarma:EasyPermission:1.0.1'

如何请求许可：

 List<String> permission = new ArrayList<>();
 permission.add(EasyPermissionList.READ_EXTERNAL_STORAGE);
 permission.add(EasyPermissionList.ACCESS_FINE_LOCATION);

 new EasyPermissionInit(MainActivity.this, permission);

希望对大家有所帮助。

Answer 18

我使用RxPermission library library 请求许可。因为代码很长，我们必须写请求许可。

RxPermissions rxPermissions = new RxPermissions(this); // where this is an Activity instance // Must be done during an initialization phase like onCreate
rxPermissions
    .request(Manifest.permission.CAMERA)
    .subscribe(granted -> {
        if (granted) { // Always true pre-M
           // I can control the camera now
        } else {
           // Oups permission denied
        }
    });

在你的 build.gradle

中添加这些依赖项

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation 'com.github.tbruyelle:rxpermissions:0.10.1'
    implementation 'com.jakewharton.rxbinding2:rxbinding:2.1.1'
}

Answer 19

应用程序中任意位置的运行时权限Here is Example

use dependency
maven { url 'https://jitpack.io' }
dependencies {
implementation 'com.github.irshadsparky:PermissionLib:master-SNAPSHOT'
}

并像这样调用代码：

PermissionHelper.requestCamera(new PermissionHelper.OnPermissionGrantedListener() {
@Override
public void onPermissionGranted() {

}
});

Answer 20

我浏览了所有答案，但没有满足我确切需要的答案，所以这是我写的一个完美运行的示例，甚至用户点击 不再询问复选框。

创建一个方法，当您想要请求运行时权限时将被调用，例如 readContacts() 或者您也可以 openCamera() 如下所示：
```
private void readContacts() {
    if (!askContactsPermission()) {
        return;
    } else {
        queryContacts();
    } }
```

现在我们需要制作 askContactsPermission()，您也可以将其命名为 askCameraPermission() 或您要请求的任何权限。

    private boolean askContactsPermission() {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
        return true;
    }
    if (checkSelfPermission(READ_CONTACTS) == PackageManager.PERMISSION_GRANTED) {
        return true;
    }
    if (shouldShowRequestPermissionRationale(READ_CONTACTS)) {
        Snackbar.make(parentLayout, R.string.permission_rationale, Snackbar.LENGTH_INDEFINITE)
                .setAction(android.R.string.ok, new View.OnClickListener() {
                    @Override
                    @TargetApi(Build.VERSION_CODES.M)
                    public void onClick(View v) {
                        requestPermissions(new String[]{READ_CONTACTS}, REQUEST_READ_CONTACTS);
                    }
                }).show();
    } else if (contactPermissionNotGiven) {
        openPermissionSettingDialog();
    } else {
        requestPermissions(new String[]{READ_CONTACTS}, REQUEST_READ_CONTACTS);
        contactPermissionNotGiven = true;

    }
    return false;
}

在编写此函数之前，请确保您已经定义了以下实例变量，如下所示：

    private View parentLayout;
    private boolean contactPermissionNotGiven;;


/**
 * Id to identity READ_CONTACTS permission request.
 */
private static final int REQUEST_READ_CONTACTS = 0;

现在是覆盖 onRequestPermissionsResult 方法的最后一步，如下所示：

/**
 * Callback received when a permissions request has been completed.
 */
@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNull int[] grantResults) {
    if (requestCode == REQUEST_READ_CONTACTS) {
        if (grantResults.length == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            queryContacts();
        }
    }
}

这里我们完成了运行时权限，插件是 openPermissionSettingDialog() 如果用户通过单击 不再询问 [=] 永久禁用权限，只需打开设置屏幕75=] 复选框。下面是方法：

private void openPermissionSettingDialog() { String message = getString(R.string.message_permission_disabled); AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT) .setMessage(message) .setPositiveButton(getString(android.R.string.ok), new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Intent intent = new Intent(); intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); Uri uri = Uri.fromParts("package", getPackageName(), null); intent.setData(uri); startActivity(intent); dialog.cancel(); } }).show(); alertDialog.setCanceledOnTouchOutside(true); }

我们错过了什么？ 1.定义strings.xml
中使用的字符串

<string name="permission_rationale">"Contacts permissions are needed to display Contacts."</string> <string name="message_permission_disabled">You have disabled the permissions permanently, To enable the permissions please go to Settings -> Permissions and enable the required Permissions, pressing OK you will be navigated to Settings screen</string>

正在初始化 onCreate 方法中的 parentLayout 变量

parentLayout = findViewById(R.id.content);

在AndroidManifest.xml
中定义所需的权限

<uses-permission android:name="android.permission.READ_CONTACTS" />

queryContacts 方法，根据您的需要或运行时权限，您可以在需要 permission 之前调用您的方法。在我的例子中，我只是使用加载程序来获取联系人，如下所示：

private void queryContacts() { getLoaderManager().initLoader(0, null, this);}

这工作非常愉快编码:)

Answer 21

将权限添加到 AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application ...>
 ....
</application>

检查 Android 版本是否需要运行时权限。

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1) {
    askForPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE, 1);
}

如果未授予权限，则要求用户授予权限。

private void askForPermission(String permission, int requestCode) {
    if (ContextCompat.checkSelfPermission(c, permission)
            != PackageManager.PERMISSION_GRANTED) {
        if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, permission)) {
            Toast.makeText(c, "Please grant the requested permission to get your task done!", Toast.LENGTH_LONG).show();
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{permission}, requestCode);
        } else {
            ActivityCompat.requestPermissions(MainActivity.this, new String[]{permission}, requestCode);
        }
    }
}

如果是否授予权限，请执行某些操作。

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case 1:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //permission with request code 1 granted
                Toast.makeText(this, "Permission Granted" , Toast.LENGTH_LONG).show();
            } else {
                //permission with request code 1 was not granted
                Toast.makeText(this, "Permission was not Granted" , Toast.LENGTH_LONG).show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

运行时间权限在 activity 中创建了大量耦合度很高的样板代码。为了减少代码并使事情变得简单，您可以使用 Dexter 库。

Answer 23

ANDROID

中的运行时权限

private static final int PERMISSION_REQ_WRITE_EXTERNAL_STORAGE = 101;

public void onClick(View view) {
    if (view.getId() == yourBtn.getId()) {
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
            this.storageWork();
        } else {
            ActivityCompat.requestPermissions(this, new String[] { Manifest.permission.WRITE_EXTERNAL_STORAGE }, PERMISSION_REQ_WRITE_EXTERNAL_STORAGE);
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if (requestCode == PERMISSION_REQ_WRITE_EXTERNAL_STORAGE) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            this.storageWork();
        }
    }
}

public void storageWork(){
}

OnClick方法是检查运行时权限

如果权限受到限制，那么它会请求权限

Answer 24

如果您正在使用 AndroidX Activity 1.2.0 or AndroidX Fragment 1.3.0:

有新的 Activity 结果 API 可用于请求权限：

val launcher = registerForActivityResult(ActivityResultContracts.RequestPermission()) { isGranted ->
    if (isGranted) {
        // Permission granted. Do the tasks.
    }
}
launcher.launch(Manifest.permission.ACCESS_FINE_LOCATION)

我从我的旧代码中找到了一个解决方案，它真的很好用，仍在使用我的最新应用程序。

将其放在 MainActivity Class 或您的 Start Activity Class

private RequestPermissionHandler mRequestPermissionHandler;

创建时

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
   mRequestPermissionHandler = new RequestPermissionHandler();
   handleButtonClicked();
}

私有函数 handleButtonClicked()

private void handleButtonClicked() {
        mRequestPermissionHandler.requestPermission(this, new String[]{
                Manifest.permission.WRITE_EXTERNAL_STORAGE,
                Manifest.permission.READ_EXTERNAL_STORAGE,
                Manifest.permission.INTERNET,
                Manifest.permission.ACCESS_COARSE_LOCATION,
                Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.READ_PHONE_STATE,
                Manifest.permission.ACCESS_NETWORK_STATE,
                Manifest.permission.WAKE_LOCK

        }, 123, new RequestPermissionHandler.RequestPermissionListener() {
            @Override
            public void onSuccess() {
                //Toast.makeText(MainActivity.this, "request permission success", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailed() {
                Toast.makeText(MainActivity.this, "request permission failed", Toast.LENGTH_SHORT).show();
