Android请求权限只请求第一个

Question

我在 Android 应用程序中工作，我已经在我的 Activity.

中声明了方法 requestAppPermissions

好吧，这段代码发生了什么，出于某种原因，它请求第一个（在本例中为位置）并跳过其他；但是，我将一些其他权限移至第一个 if 该方法请求第一个，跳过其他权限。

我的代码有什么问题？

public void requestAppPermissions(){
    if (Build.VERSION.SDK_INT >= 21) {
        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.ACCESS_FINE_LOCATION)) {
                //El usuario denegó los permisos con el botón "Don't show again!!!"
                startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
            } else {
                //Se solicita el permiso al usuario
                ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1);
            }
        }else{
            LocationManager lm = (LocationManager) this.getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
            Location location = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

            if(location != null){
                Double latitude = location.getLatitude();
                Double longitude = location.getLongitude();
                //new MapFunctions().RecenterMap(googleMap, new LatLng(latitude, longitude), 14, "");
                LOCATION_CENTER = new LatLng(latitude, longitude);
                // Toast.makeText(MainActivity.this, "latitude: " + latitude + " - longitude" + longitude, Toast.LENGTH_LONG).show();
            }
        }

        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.CAMERA)) {
                startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
            } else {
                ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.CAMERA}, 2);
            }
        }

        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
            } else {
                ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 3);
            }
        }

        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.READ_EXTERNAL_STORAGE)) {

            } else {
                ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.READ_EXTERNAL_STORAGE}, 4);
            }
        }

    }
}

类似的内容可能会有所帮助...

String[] neededPermissions = new String[]{
    android.Manifest.permission.ACCESS_FINE_LOCATION,
    android.Manifest.permission.CAMERA,
    android.Manifest.permission.WRITE_EXTERNAL_STORAGE //if you can write, you can read
}

public static List<String> getPermissionsRequest(@NonNull Context context, 
                                                 @NonNull String[] permissions){
    List<String> permissionsToRequest = new ArrayList<>();
    for (int i = 0; i < permissions.length; i++){
        if (ContextCompat.checkSelfPermission(context, permissions[i]) 
                  != PackageManager.PERMISSION_GRANTED){
            permissionsToRequest.add(permissions[i]);
        }
    }
    return permissionsToRequest;
}

//now in the onCreate of your Activity you can do something like this:
List<String> permissionsToRequest = getPermissionsRequest(this, neededPermissions);
//if permissionsToRequest size is > 0 you need some more permission(s)
if (permissionsToRequest.size() > 0){
    ActivityCompat.requestPermissions(MainActivity.this,
         permissionsToRequest.toArray(new String[0]), PERMISSION_ALL_REQUEST_CODE);
}

//now in the onRequestPermissionsResult you can handle everything
//as always and proceeed if everything is ok

我目前还没有测试过这个，但应该可以工作
