【中文标题】在谷歌地图自定义标记未显示在三星 S8 或 Android 的相同版本 7.0

【英文标题】：In Google Maps Custom Marker not Showing in Samsung S8 or same version 7.0 in Android

【问题描述】：

我正在创建一个带有自定义纬度和经度标记的谷歌地图。标记在三星 S4 手机上正常显示，但在 S8 或更高版本上不显示。我为此授予所有许可。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 中无法正常工作。

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();



private void requestPermission() 
    ActivityCompat.requestPermissions(getActivity(), new
            String[]Manifest.permission.ACCESS_FINE_LOCATION, 1);



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

                    item.getLongitude())).title(item.getName()).anchor(0.5f,
                    0.5f).icon(BitmapDescriptorFactory.fromBitmap(getCustomMarker(

【问题讨论】：

如果它显示在 S4 中，则标记代码不是问题。请将您的代码发布在您要求权限的地方。

我授予所有权限

所以你在授予权限后添加标记？你确定是这样吗？

首先我授予所有权限，然后设置地图并添加标记

你的onRequestPermissionsResult方法在哪里？

【参考方案1】：

试试这个

@Override

    try

   MainActivity.this, 
   R.raw.style_json));

        if (!success) 
            Log.e("google map", "Style parsing failed.");
        
     catch (Resources.NotFoundException e)
