安卓 6.0+ : Method onRequestPermissionsResult not call

Question

这是我的 map fragment :

public class MapFragmentTab extends Fragment implements OnMapReadyCallback {
    private GoogleMap googleMap;
    private GoogleApiClient mGoogleApiClient;
    private static final int MY_PERMISSION_LOCATION = 1;   

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        rootView = inflater.inflate(R.layout.map_fragment_tab, container, false);
        init();
        return rootView;
    }

    private void init() {
        if (mGoogleApiClient == null) {
            mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                    .addApi(LocationServices.API)
                    .build();
        }
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) 
        mapView = rootView.findViewById(R.id.mapView);
        if (mapView != null) {
            mapView.onCreate(null);
            mapView.onResume();
            mapView.getMapAsync(this);
        }
    }

    @Override
    public void onMapReady(GoogleMap map) {
        googleMap = map;       
        int permissionCheck = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION);
        if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSION_LOCATION);
        } else {                
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
         // some code here
        }
    }          

在 Android 4.3 上一切正常。

但是当我第一次在 Android 6.0+ 上启动时，然后显示提示对话框以获得权限。像这样:

Allow My application to access this device's location?

Deny Allow

我点击了允许，但是onRequestPermissionsResult 方法没有被调用。 我的代码有什么问题？

Answer 1

而不是调用

ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSION_LOCATION)

这样调用

requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSION_LOCATION, PERMISSIONS_CODE)

当你使用android.support.v4.app.Fragment时，你必须调用requestPermissions。

在AppCompatActivity时，应该使用ActivityCompat.requestPermissions；
