onRequestPermissionsResult从不在片段[duplicate]中调用

Question

下面的代码在活动中运行良好，但我不能使它在片段中工作。

从不调用OnRequestPermissionsResult。

public class MyFragment extends Fragment {

final int REQUEST_CODE = 120;

@Override
public View onCreateView(LayoutInflater infl, ViewGroup cont, Bundle bundle) {

    if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
        Log.i("LOG", "Asking for permission right now..");

        ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.READ_CONTACTS}, REQUEST_CODE);


        //This is working but needs API level 23 (Android 6.0) - How to make this work on Android 5.0?
        //requestPermissions( new String[]{Manifest.permission.READ_CONTACTS}, REQUEST_CODE);
    }

    return super.onCreateView(infl, cont, bundle);
}

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

    Log.i("LOG", "onRequestPermissionsResult!");

    if (requestCode == REQUEST_CODE) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Log.i("LOG", "GRANTED");
            Toast.makeText(getActivity(), "GRANTED,", Toast.LENGTH_LONG).show();

        } else {
            Log.i("LOG", "REFUSED");
            Toast.makeText(getActivity(), "REFUSED,", Toast.LENGTH_LONG).show();
        }
    }
}
}

在宿主活动的onRequestPermissionResult内部调用Fragment.onRequestPermissionResult。
