本文介绍了Google地图中的自定义标记不显示在Samsung S8或同一版本7.0中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
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（） ;
/ **创建虚拟标记列表* /
列表<标记> markersList = new ArrayList< Marker>（）;
（City item：cityList）
{
if（googleMap！= null）{
Marker m1 = googleMap.addMarker（new MarkerOptions（）。position新的
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（）
{
@Override
public boolean onMarkerClick（final Marker marker ）{
ValueAnimator ani = ValueAnimator.ofFloat（0,1）; //如果您想要在

（0,1）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（）））
{
AppUtil.city = cityList.get（1）;
$ b else if（marker.getTitle（）。equals（cityList.get（2）.getName（）））
{
AppUtil.city = cityList获得（2）;
$ b else if（marker.getTitle（）。equals（cityList.get（3）.getName（）））
{
AppUtil.city = cityList获得（3）;
$ b else if（marker.getTitle（）。equals（cityList.get（4）.getName（）））
{
AppUtil.city = cityList获得（4）;
FragmentTransaction transaction =
getFragmentManager（）。beginTransaction（）;
transaction.replace（R.id.frame_container，new
CityDetailFragment（））;
transaction.commit（）;
/ *（（CityDetailFragment）adapter.getItem（1））。setupData（）;
viewPager.setCurrentItem（1，false）; * /
返回true;
}
}）;
/ **创建for循环以从标记列表中获取latLngbuilder * /
builder = new LatLngBounds.Builder（）; （Marker m：markersList）{
builder.include（m.getPosition（））;
}
/ **初始化地图边界的填充* /

final LatLngBounds bounds = builder.build（）;
/ **创建带有边界和填充的摄像头以设置为地图* /

在此输入代码

@Override
public void onMapLoaded（）{
googleMap.moveCamera（CameraUpdateFactory.newLatLngBounds（bounds，
padding））;
googleMap.animateCamera（CameraUpdateFactory.zoomTo （12））;

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()))
{
AppUtil.city=cityList.get(1);
}
else if(marker.getTitle().equals(cityList.get(2).getName()))
{
AppUtil.city=cityList.get(2);
}
else if(marker.getTitle().equals(cityList.get(3).getName()))
{
AppUtil.city=cityList.get(3);
}
else if(marker.getTitle().equals(cityList.get(4).getName()))
{
AppUtil.city=cityList.get(4);
}
FragmentTransaction transaction =
getFragmentManager().beginTransaction();
transaction.replace(R.id.frame_container, new
CityDetailFragment());
transaction.commit();
/*((CityDetailFragment) adapter.getItem(1)).setupData();
viewPager.setCurrentItem(1,false);*/
return true;
}
});
/**create for loop for get the latLngbuilder from the marker list*/
builder = new LatLngBounds.Builder();
for (Marker m : markersList) {
builder.include(m.getPosition());
}
/**initialize the padding for map boundary*/

解决方案
Try This
public class MainActivity extends AppCompatActivity implements

@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();
}
private static final String TAG = "MapActivity";
private static final String FINE_LOCATION =
Manifest.permission.ACCESS_FINE_LOCATION;

Manifest.permission.ACCESS_COARSE_LOCATION;

private Boolean mLocationPermissionsGranted = false;
private GoogleMap mMap;

}

}
}else{

}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull

Log.d(TAG, "onRequestPermissionsResult: called.");

switch (requestCode) {
case LOCATION_PERMISSION_REQUEST_CODE : {
// If request is cancelled, the result arrays are empty.
