Android的谷歌地图V2的标签重叠的问题,在选项卡多地图 [英] Android Google map v2 in tab Overlapping issue, Multiple map in tab
问题描述
我是新来的机器人,现在正与谷歌地图V2的工作,我已经使用tabhost显示谷歌地图V2,在这种tabhost我需要显示不同的选项卡上的两个谷歌地图V2。当我切换/黑白两个选项卡包含的地图选项卡,它得到重叠。我不知道解决这个问题。
I am new to android, now am working with Google maps v2, I have used tabhost to show Google map v2, In this tabhost i need to show two Google maps v2 on different tab. When i switch the tab b/w two tabs which contain map, it get overlapped. I don't know to overcome this issue.
// code是在这里为标签
//code is here for both tab
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);
}
任何人有解决方案,请帮助我。

推荐答案
我也面临着同样的问题,但最后我还是设法做到了这个样子。
I have faced the same issue but finally i managed it in this way.
首先,我创建延伸android.support.v4.app.Fragment独立MyMapFragment类
First of all i create separate MyMapFragment class which extends android.support.v4.app.Fragment
这里是onCreateView方法
here is the onCreateView method
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,我创建一个XML文件
after that i create one xml file
<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>
您可以添加此布局文件到您的地图布局的地方
You can add this layout file into your map layout place
最后你可以选择使用这个添加地图视图在activty类
and finally you have to add map view using this one in your activty class
MyMapFragment newFragment = new MyMapFragment (1);
FragmentTransaction transaction = getActivity()
.getSupportFragmentManager().beginTransaction();
transaction.add(R.id.my_fragmentView, newFragment);
transaction.commit();
它的正常工作在我身边,我希望它可以帮助你。
It's working fine at my side i hope it helps you.
MapFragment code是这里
public class MapFragment extends Fragment {
private View view;
private GoogleMap mMapView;
public TouchableWrapper mTouchView;
LinearLayout map_fragg;
String userLat, userLon;
int maptype = 1;
Marker lastMarker = null;
public MapFragment() {
}
public MapFragment(int maptype) {
this.maptype = maptype;
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
getView();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
return null;
}
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null)
parent.removeView(view);
if (mTouchView != null) {
mTouchView.removeAllViews();
}
}
try {
mTouchView = new TouchableWrapper(getActivity());
view = (ViewGroup) inflater.inflate(R.layout.map_frag, null, false);
view.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
map_fragg = (LinearLayout) view.findViewById(R.id.map_fragg);
mTouchView.addView(view);
setUpMapIfNeeded();
} catch (Exception e) {
e.printStackTrace();
}
return mTouchView;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
private void showMap(int maptype) {
switch (maptype) {
case 1:
setMapX();
break;
case 2:
setMapXX();
break;
case 3:
setUpMapXXX();
break;
default:
break;
}
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the
// map.
if (mMapView == null) {
// Try to obtain the map from the SupportMapFragment.
mMapView = ((SupportMapFragment) getActivity()
.getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMapView != null) {
setUpMap();
showMap(maptype);
}
}
}
private void setUpMap() {
mMapView.setMyLocationEnabled(true);
}
// Setting up map for MyProfile Page
private void setMapX() {
// Your Code for adding Markers
}
// Setting up map for MyProfile Page
private void setMapXX() {
// Your Code for adding markers
}
public class TouchableWrapper extends FrameLayout {
public TouchableWrapper(Context context) {
super(context);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
this.getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_UP:
this.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
return super.dispatchTouchEvent(ev);
}
}
@Override
public void onStop() {
super.onStop();
try {
SupportMapFragment f = (SupportMapFragment) getFragmentManager()
.findFragmentById(R.id.map);
if (f != null)
getFragmentManager().beginTransaction().remove(f).commit();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onDestroyView() {
super.onDestroyView();
}
@Override
public View getView() {
if (view != null) {
return view;
}
return super.getView();
}
private void setUpMapXXX() {
// Your Code for adding Markers
}
}
