android - Google map 中的自定义标记未在三星 S8 或相同版本 7.0 中显示

Question

我是一名新的 Android 开发者。我正在使用经纬度 map 创建谷歌地图和自定义标记，标记在 S4 移动设备中正常工作和显示，但在 s8 或更高版本的移动设备中未显示，我授予所有权限。我还将点击监听器放在自定义标记上。这些在 s4 或低版本移动设备中都可以正常工作，但在高版本 api 移动设备中不起作用。提前致谢..
我哪里错了？请帮我 这是我的代码

public void mSetUpMap() {
googleMap.clear();
/**Create dummy Markers List*/
List<Marker> markersList = new ArrayList<Marker>();
for (City item :  cityList)
{

if (googleMap !=null) {
 Marker m1 = googleMap.addMarker(new MarkerOptions().position(new 
   LatLng(item.getLatitude(), 
   item.getLongitude())).title(item.getName()).anchor(0.5f, 
   0.5f).icon(BitmapDescriptorFactory.fromBitmap(getCustomMarker(
   item.getDrawableId(), item.getName()))));
            markersList.add(m1);
        }

    }
    googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() 
    {
        @Override
        public boolean onMarkerClick(final Marker marker) {
            ValueAnimator ani = ValueAnimator.ofFloat(0,1); //change for 
           (0,1) if you want a fade in
            ani.setDuration(2000);
            ani.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() 
              {
                @Override
                public void onAnimationUpdate(ValueAnimator animation) {
                    marker.setAlpha((float) animation.getAnimatedValue());
                }

            });
            ani.start();
            if(marker.getTitle().equals(cityList.get(0).getName()))

试试这个

public class MainActivity extends AppCompatActivity implements

@Override

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);
