Android谷歌地图v2在标签重叠问题，多个地图在标签

我是android新手，现在正在使用Google maps v2，我使用tabhost显示Google map v2，在这个tabhost中，我需要在不同的选项卡上显示两个Google maps v2。当我切换选项卡b/w两个包含map的选项卡时，它会重叠。我不知道如何克服这个问题

//这两个选项卡的代码都在这里

    mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
            .getMap();
    mMap.setMyLocationEnabled(true);

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    //locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME, MIN_DISTANCE, this);
    Log.e("locamanager",""+locationManager);
    Criteria criteria=new Criteria(); // object to retrieve provider
    String provider = locationManager.getBestProvider(criteria, true);
    Location location=locationManager.getLastKnownLocation(provider);
    if(location!=null){
        onLocationChanged(location);
    }
    locationManager.requestLocationUpdates(provider, 400, 1000, this);


 }


@Override
public void onLocationChanged(Location location) {

    latLng = new LatLng(location.getLatitude(), location.getLongitude());
    Log.e("latlng",""+latLng);
    cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 15);
    mMap.animateCamera(cameraUpdate);
    locationManager.removeUpdates(this);

    new ReverseGeocodingTask(getBaseContext()).execute(latLng);

}

谁有办法，请帮帮我

感谢您的帮助

我也遇到过同样的问题，但最终还是以这种方式解决了

首先，我创建了单独的MyMapFragment类，它扩展了android.support.v4.app.Fragment

下面是onCreateView方法

if (view != null) {

            ViewGroup parent = (ViewGroup) view.getParent();
            if (parent != null)
                parent.removeView(view);
        }

        try {
            view = (ViewGroup) inflater.inflate(R.layout.map_frag, container,
                    false);
            setUpMapIfNeeded();
            showMap(maptype);
        } catch (Exception e) {
        }
        return view;

之后，我创建了一个xml文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_fragmentView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
</LinearLayout>

在我这边很好，希望对你有帮助

        return super.getView();
    }



    private void setUpMapXXX() {
        // Your Code for adding Markers
    }

}

我也有同样的问题（google maps v2在一个选项卡中只显示了一个灰色网格，但如果我将其作为一个没有选项卡的主要活动加载，它就会工作）

然后我添加了mMapFragment.onResume（），现在它在一个选项卡中工作！试试这个：

mMapFragment = ((MapFragment) getFragmentManager().findFragmentById(R.id.map));
mMapFragment.onResume(); // needed to get the map to display immediately

我在这里找到了解决方案：

只要使用这个类

public class MapFragment extends SupportMapFragment {

    GoogleMap mapView;
    private Context context;

    @Override
    public void onCreate(Bundle arg0) {
            super.onCreate(arg0);
    }

    @Override
    public View onCreateView(LayoutInflater mInflater, ViewGroup arg1,
                    Bundle arg2) {
            View view = super.onCreateView(mInflater, arg1, arg2);
              setMapTransparent((ViewGroup) view);
              return view;
    }

    private void setMapTransparent(ViewGroup group) {
            int childCount = group.getChildCount();
            for (int i = 0; i < childCount; i++) {
            View child = group.getChildAt(i);

                    if (child instanceof ViewGroup) {
                        setMapTransparent((ViewGroup) child);
                    } else if (child instanceof SurfaceView) {
                        child.setBackgroundColor(0x00000000);
                    }
                }
            }

    @Override
    public void onInflate(Activity arg0, AttributeSet arg1, Bundle arg2) {
            super.onInflate(arg0, arg1, arg2);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState);
            context = getActivity();
            mapView = getMap();

            }
}

公共类MapFragment扩展了SupportMapFragment{
谷歌地图地图视图；
私人语境；
@凌驾
创建公共void（包arg0）{
super.onCreate（arg0）；
}
@凌驾
创建视图上的公共视图（LayoutFlater mInflater，视图组arg1，
捆绑包arg2）{
View=super.onCreateView（mInflater，arg1，arg2）；
setMapTransparent（（视图组）视图）；
返回视图；
}
私有void setMapTransparent（视图组）{
int childCount=group.getChildCount（）；
for（int i=0；i

使用

选项卡活动

？请发布一些代码。上面的代码我用于两个选项卡，但我使用不同的布局名称。我确实坚持解决选项卡中重叠的地图碎片，如果你有任何解决方案，请帮助我。我有相同的问题，使用上面的代码，它运行良好，解决了mapv2+选项卡问题…是的，但如何在我的活动中使用片段类。请查看xml布局。我在map_fragg=（LinearLayout）view.findViewById（R.id.map_fragg）中发现您的类有错误；我在两个不同的选项卡上打开我的地图活动，并处理一些条件。在“地图”选项卡上，用户显示完整地图视图，在“搜索”选项卡上，用户使用editbox显示相同的地图以搜索任何位置。但其重叠旧地图bro。我在这个问题上坚持了4天，但没有得到任何完美的解决方案，所以请帮我解决这个问题。非常感谢你，兄弟。来聊天室吧
