Google地图中的自定义标记不显示在Samsung S8或同一版本7.0中 [英] Custom Marker In Google Maps not Showing in Samsung S8 or same version 7.0

问题描述

我是一名新的Android开发者。我创建谷歌地图和自定义标记与纬度长的地图和标记工作和显示适当的S4手机，但没有显示在s8或更高版本的手机我授予所有权限。我也把点击监听器在自定义标记。这些在s4或低版本手机中都可以正常工作，但不适用于高版本api手机。在此先感谢..

我错了吗？请帮助我
这里是我的代码

$ public $ mSetUpMap（）{
googleMap.clear（） ;

LatLng（item.getLatitude（），
item.getLongitude（）））。title（item.getName（））。anchor（0.5f，
0.5f）.icon（BitmapDescriptorFactory .fromBitmap（getCustomMarker（
item.getDrawableId（），item.getName（）））））;
markersList.add（m1）;


$ b googleMap.setOnMarkerClickListener（new GoogleMap.OnMarkerClickListener（）

查看markerLayout = view.inflate（null，

markerLayout.measure（View.MeasureSpec.makeMeasureSpec（0，
View.MeasureSpec.UNSPECIFIED），View.MeasureSpec.makeMeasureSpec（0，

I am a new Android Developer. I am creating google map and custom marker with lat long map and markers work and show proper in S4 mobile but not shown in s8 or higher version mobile I grant all permission for that.I also put click listener on Custom Marker. These all work fine in s4 or low version mobile but not work in high version api mobile. Thanks in Advance..
where i am wrong ? please help me Here is my code

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

   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()

Try This

@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();
