片段中函数的无法访问语句

Question

我有一个片段，我想在其中显示地图，我现在已经这样做了，但是当我调用函数时，它会抛出一个无法访问的错误。public class HomeFragment extends Fragment { private static final String TAG = "HomeFragment"; private static final String FINE_LOCATION = Manifest.permission.ACCESS_FINE_LOCATION; private static final String COARSE_LOCATION = Manifest.permission.ACCESS_COARSE_LOCATION; //vars private Boolean mLocationPermissionsGranted = false; private static final int LOCATION_PERMISSION_REQUEST_CODE = 1234; private GoogleMap mMap; @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {  return inflater.inflate(R.layout.layout_home, container, false);  getLocationPermision(); } private void initMap() {  SupportMapFragment mapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.map);  mapFragment.getMapAsync(new OnMapReadyCallback() {   @Override   public void onMapReady(GoogleMap googleMap) {    mMap = googleMap;   }  }); } private void getLocationPermision() {  String[] permissions = {   Manifest.permission.ACCESS_FINE_LOCATION,   Manifest.permission.ACCESS_COARSE_LOCATION  };  if (ContextCompat.checkSelfPermission(this.getActivity().getApplicationContext(), FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {   if (ContextCompat.checkSelfPermission(this.getActivity().getApplicationContext(), COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {    mLocationPermissionsGranted = true;   }  } else {   ActivityCompat.requestPermissions(this.getActivity(), permissions, LOCATION_PERMISSION_REQUEST_CODE);  } }当我尝试打电话时getLocationPermission()它让我你能帮我一下吗？我应该在主要活动中进行这些权限验证吗？在主要活动中，我只有一个导航栏，当然我想处理片段。

Answer 1

@Nullable

@Override

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    return inflater.inflate(R.layout.layout_home,container,false);

    getLocationPermision();

}

getLocationPermision();在您的 return 语句之后调用。使其无法到达。

将其移至 return 语句之前。
