在用户单击“不再询问权限”时，我遇到了位置权限被拒绝的问题-屏幕开始闪烁。
如果用户单击“拒绝”按钮并且不再次询问，则未选中，因此权限弹出窗口再次出现。
我想要，当用户选中“不再询问”复选框并单击“拒绝”时，他将被重定向到设置以手动打开位置。
有我的权限检查和询问代码。
public boolean checkLocationPermission() {
if (ContextCompat.checkSelfPermission(context, // Changed from getActivity()
Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, // Changed from getActivity()
Manifest.permission.ACCESS_FINE_LOCATION)) {
// Show an explanation 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.
new AlertDialog.Builder(context
, R.style.AlertDialogCustom)
.setTitle("Location permission")
.setIcon(R.drawable.location_icon)
.setMessage("Some text here")
.setPositiveButton("OK!", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//Prompt the user once explanation has been shown
ActivityCompat.requestPermissions(activity, // Changed from getActivity()
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSIONS_REQUEST_LOCATION);
}
})
.create()
.show();
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(activity, // Changed from getActivity()
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSIONS_REQUEST_LOCATION);
}
return false;
} else {
return true;
}
}
关于许可结果：
@Override
public void onRequestPermissionsResult(int requestCode,
@NonNull String[] permissions, @NonNull int[] grantResults) {
// If request is cancelled, the result arrays are empty.
if (requestCode == MY_PERMISSIONS_REQUEST_LOCATION) {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// location-related task you need to do.
if (ContextCompat.checkSelfPermission(context, // Changed from getActivity()
Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
//Request location updates:
}
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
return;
}
}
将用户重定向到设置的功能：
public static void startInstalledAppDetailsActivity(final Activity context) {
if (context == null) {
return;
}
final Intent i = new Intent();
i.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
i.addCategory(Intent.CATEGORY_DEFAULT);
i.setData(Uri.parse("package:" + context.getPackageName()));
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
i.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
context.startActivity(i);
}
