android - 在谷歌地图自定义标记不显示在三星 S8 或相同版本 7.0 在 Android

Question

我正在创建一个带有自定义纬度和经度标记的 Google map 。这些标记在 Samsung S4 手机上正确显示，但在 S8 或更高版本上不显示。我授予所有许可。我还将点击监听器放在自定义标记上。这些在 S4 或低版本中都可以正常工作，但在高版本 api mobile 中不起作用。

我哪里错了？这是我的代码:

if (ActivityCompat.checkSelfPermission(getActivity(),
        Manifest.permission.ACCESS_FINE_LOCATION) !=
        PackageManager.PERMISSION_GRANTED &&
        ActivityCompat.checkSelfPermission(getActivity(),
                Manifest.permission.ACCESS_COARSE_LOCATION) !=
                PackageManager.PERMISSION_GRANTED) {
    requestPermission();
    // 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 false;
} else {

    mSetUpMap();
}

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) {
