Question

我是一名新的Android开发人员。我正在创建谷歌地图和自定义标记与lat长地图和标记工作并在S4手机中显示正确但未在s8或更高版本的移动设备中显示我授予了所有权限。我还在自定义标记上放置了点击监听器。这些都可以在s4或低版本移动设备上正常工作，但在高版本的api mobile中无法正常工作。在此先感谢..

试试这个

public class MainActivity extends AppCompatActivity implements 
OnMapReadyCallback {

@Override
 public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;

try {

    boolean success = 

googleMap.setMapStyle(MapStyleOptions.loadRawResourceStyle(
MainActivity.this, 
R.raw.style_json));

    if (!success) {
        Log.e("google map", "Style parsing failed.");
    }
} catch (Resources.NotFoundException e) {
    Log.e("google map", "Can't find style. Error: ", e);
}

mSetUpMap();

}



private static final String TAG = "MapActivity";

private static final String FINE_LOCATION = 
Manifest.permission.ACCESS_FINE_LOCATION;
private static final String COURSE_LOCATION = 
Manifest.permission.ACCESS_COARSE_LOCATION;

private static final int LOCATION_PERMISSION_REQUEST_CODE = 1234;


 private Boolean mLocationPermissionsGranted = false;
 private GoogleMap mMap;

 @Override
 protected void onCreate(@Nullable Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  getLocationPermission();
 }

 private void initMap(){
 Log.d(TAG, "initMap: initializing map");
 SupportMapFragment mapFragment = (SupportMapFragment) 
 getSupportFragmentManager().findFragmentById(R.id.map);

 mapFragment.getMapAsync(MainActivity.this);
 }

  private void getLocationPermission(){
  Log.d(TAG, "getLocationPermission: getting location permissions");
  String[] permissions = {Manifest.permission.ACCESS_FINE_LOCATION,
        Manifest.permission.ACCESS_COARSE_LOCATION};

  if(ContextCompat.checkSelfPermission(this.getApplicationContext(),
        FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){
    if(ContextCompat.checkSelfPermission(this.getApplicationContext(),
            COURSE_LOCATION) == PackageManager.PERMISSION_GRANTED){
        mLocationPermissionsGranted = true;
        initMap();
    }else{
        ActivityCompat.requestPermissions(this,
                permissions,
                LOCATION_PERMISSION_REQUEST_CODE);
    }
   }else{
    ActivityCompat.requestPermissions(this,
            permissions,
            LOCATION_PERMISSION_REQUEST_CODE);
   }
 }

 @Override
 public void onRequestPermissionsResult(int requestCode, @NonNull 
 String[] permissions, @NonNull int[] grantResults) {
 Log.d(TAG, "onRequestPermissionsResult: called.");
 mLocationPermissionsGranted = false;




     switch (requestCode) {

        case LOCATION_PERMISSION_REQUEST_CODE : {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                    && grantResults[0] == 
    PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.
                Toast.makeText(getApplicationContext(), "Permission 
 granted", Toast.LENGTH_SHORT).show();
                initMap();

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
                Toast.makeText(getApplicationContext(), "Permission 
   denied", Toast.LENGTH_SHORT).show();
            }
            return;
        }

    }


    }
private void mSetUpMap() {
 // your method code 

 }
}

自定义标记在Google地图中不显示在Samsung S8或相同版本7.0中
