我知道这是一个权限问题，我可以像这样授予权限来解决：
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Manifest.permission.READ_CONTACTS)) {
// Show an expanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
然后使用它来设置对我的提供商的权限：
@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
}
}
问题是我不知道我必须在项目的哪一部分提出此权限请求：
我正在使用 Auth0 Custom UI 登录验证，Mysqlite 作为内部数据库，GoogleCards 作为 ListView。
你能帮我了解如何授予此权限拒绝吗？
非常感谢
自然要放在任意Activity里面。您的应用 运行 是否需要此功能？在应用程序启动时询问。如果您的应用程序可以在没有它的情况下运行 - 在不可避免地阅读联系人时询问（在一个视图中）。
好吧，我建议使用 Ask，它是一个权限帮助程序库。
使用它，您无需编写太多代码，只需两行代码即可为您完成所有工作。
这里是使用详情。
首先，在你的 build.gradle:
中编译依赖
dependencies {
compile 'com.vistrav:ask:2.4'
}
然后在 OnCreate 中 activity 的开头或按任何按钮，您可以这样请求许可：
Ask.on(this)
.forPermissions(Manifest.permission.READ_CONTACTS)
.go();
就是这样。
您可以找到更多信息here。我几乎在我所有的项目中都使用它，而且简单易行。
Basically you have to check for these permission just before the code where you want to access the contacts.
First of all check for the android version,if it is >=23 then
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Manifest.permission.READ_CONTACTS)) {
// Show an expanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
else
{
// do here contact related work say you wwant to fetch the name and number from contact,you can do that task here.
}
You have to override this method:
@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
}
对于 6.0 以下的 android 版本，只需在清单中定义堆栈跟踪（READ_CONTACTS、WRITE_CONTACTS 等）中提到的权限即可。
对于 android 版本 6.0 及更高版本，您必须请求用户授予权限。理想情况下，它应该在绝对必要时完成，例如当用户导航到您的应用程序中需要该权限的部分时。已解释 here.
