我在我的应用中遇到Locator问题。我有使用用户当前位置的服务，并基于它显示来自最近市场的引脚。它在Android波纹管6.0上没有问题，但在6.0上无法获取用户位置。我假设是因为它有新的权限系统。

I have a problem with Locator in my app. I have service that use User current location and based on it it show pins from closest marketplaces. It works without problems on Android bellows 6.0 but on 6.0 it can't get user locations. I assume because of new permission system in it.

@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.locator_fragment, container, false); // Gets the MapView from the XML layout and creates it mapView = (MapView) v.findViewById(R.id.mapview); mapView.onCreate(savedInstanceState); // Gets to GoogleMap from the MapView and does initialization stuff map = mapView.getMap(); map.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() { @Override public void onMyLocationChange(final Location location) { Latitude= location.getLatitude(); Longitude= location.getLongitude(); float distance = location.distanceTo(location); Location locationzoom = map.getMyLocation(); LatLng mapCenter = new LatLng(location.getLatitude(), location.getLongitude()); if(!didSetLocation) { CameraPosition cameraPosition = CameraPosition.builder() .target(mapCenter) .zoom(13) .bearing(80) .build(); map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition), 2000, null); didSetLocation=true; } if ((lastcall!=null)?(location.distanceTo(lastcall)>1000):true) { map.clear(); NetworkSDK.getInstance().getCoordinates(Latitude, Longitude, new Callback<List<Coordinate>>() { @Override public void onResponse(Call<List<Coordinate>> call, Response<List<Coordinate>> response) { for (int i = 0; i < response.body().size(); i++) { map.addMarker(new MarkerOptions() .position(new LatLng(response.body().get(i).getLatitude(), response.body().get(i).getLongitude())) .title(response.body().get(i).getName())); } lastcall=location; } @Override public void onFailure(Call<List<Coordinate>> call, Throwable t) { Toast.makeText(getContext(), R.string.errorNoconnection, Toast.LENGTH_SHORT).show(); } }); } } }); Location mLastLocation; map.setMapType(GoogleMap.MAP_TYPE_NORMAL); map.getUiSettings().setMyLocationButtonEnabled(false); if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return v; } map.setMyLocationEnabled(true); map.isTrafficEnabled(); // Needs to call MapsInitializer before doing any CameraUpdateFactory calls MapsInitializer.initialize(this.getActivity()); // Updates the location and zoom of the MapView return v; }

我应该如何让用户选择授予应用权限？

How should I give user choice to grant permission for app?

推荐答案

private static final int REQUEST_CAMERA_PERMISSION = 1; void checkPremission() { //select which permission you want final String permission = Manifest.permission.CAMERA; // if in fragment use getActivity() if (ContextCompat.checkSelfPermission(ActivityName.this, permission) != PackageManager.PERMISSION_GRANTED) { if (ActivityCompat.shouldShowRequestPermissionRationale(ActivityName.this, permission)) { } else { ActivityCompat.requestPermissions(ActivityName.this, new String[]{permission}, REQUEST_CAMERA_PERMISSION); } } else { // you have permission go ahead } } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { switch (requestCode) { case REQUEST_CAMERA_PERMISSION: final int numOfRequest = grantResults.length; final boolean isGranted = numOfRequest == 1 && PackageManager.PERMISSION_GRANTED == grantResults[numOfRequest - 1]; if (isGranted) { // you have permission go ahead }else{ // you dont have permission show toast } break; default: super.onRequestPermissionsResult(requestCode, permissions, grantResults); } }
