谷歌地图中的自定义标记未在三星 S8 或相同版本 7.0 中显示

Custom Marker In Google Maps not Showing in Samsung S8 or same version 7.0(谷歌地图中的自定义标记未在三星 S8 或相同版本 7.0 中显示)

问题描述

我是一名新的 Android 开发人员.我正在使用 lat long 地图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并显示，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.这些都可以在 s4 或低版本的移动设备中正常工作，但不能在高版本的 api 移动设备中工作.在此先感谢..
我哪里错了?请帮我这是我的代码

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)
{

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()))
            {
                AppUtil.city=cityList.get(0);

            }
            else if(marker.getTitle().equals(cityList.get(1).getName()))
            {

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

推荐答案

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();

}

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

    }

 // your method code 

 }
}
