我有一個片段，我想在其中顯示地圖，我現在已經這樣做了，但是當我調用函數時，它會拋出一個無法訪問的錯誤。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);  } }當我嘗試打電話時getLocationPermission()它讓我你能幫我一下嗎？我應該在主要活動中進行這些權限驗證嗎？在主要活動中，我只有一個導航欄，當然我想處理片段。
