How to check permission in fragment
我想检查一下碎片内部的许可。
我的代码:
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),
android.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.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(getActivity(),
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
1);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
但是 onRequestPermissionsResult在允许或拒绝后不会调用。
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case 1: {
Log.e("test","0");
// 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.
//yes
Log.e("test","1");
Intent intent = new Intent(getActivity(), MapsActivity.class);
intent.putExtra("latitude", 35.694828);
intent.putExtra("longitude", 51.378129);
startActivity(intent);
} else {
utilityFunctions.showSweetAlertWarning(getActivity(),r.getString(R.string.str_warning_title_empty),
r.getString(R.string.str_you_must_allow_this_permission_toast),
r.getString(R.string.str_warning_btn_login));
Log.e("test","2");
}
return;
}
// other 'case' lines to check for other
// permissions this app might request
}
}
