java - fragment 中的 map [IllegalArgumentException : Binary XML file line #7: Duplicate id]

Question

所以，我有两个 fragment (F1 和F2)，F1 包含 map fragment，F2 包含一些数据。所以当我加载 fragment F1 时， map 加载完美，但是当我转到 fragment F2 并通过单击按钮(再次加载 fragment )返回 fragment 一时，我收到以下错误:

以下是我的 map fragment 代码(F1)MapsFragment.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:clickable="true"/>

</RelativeLayout>

这是java代码:MapsFragment.java

public class MapsFragment extends Fragment {

private GoogleMap googleMap;
double latitude;
double longitude;
protected LocationManager locationManager;
Context context;
boolean isNetworkAvailable = false;
Location location;

public MapsFragment() {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_maps, container,
            false);

    try {
        initializeMap();

        LatLng pos = new LatLng(latitude, longitude);
        MarkerOptions marker = new MarkerOptions()
                .position(pos)

                        .fromResource(R.drawable.marker));
        MarkerOptions marker1 = new MarkerOptions()
                .position(new LatLng(18.90370, 72.81314))
                .title("Zaffran")

                .fillColor(Color.parseColor("#25f67f21"));

        googleMap.addMarker(marker);
        googleMap.addMarker(marker1);
        googleMap.addCircle(circle);
        googleMap.addCircle(circle1);

        CameraPosition cp = new CameraPosition.Builder()
                .target(new LatLng(latitude, longitude)).zoom(10).build();
        googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cp));

        googleMap.setMyLocationEnabled(true);
        googleMap.getUiSettings().setZoomControlsEnabled(true);
        googleMap.getUiSettings().setMyLocationButtonEnabled(true);
        googleMap.getUiSettings().setCompassEnabled(true);
        googleMap.getUiSettings().setZoomGesturesEnabled(true);
        googleMap.getUiSettings().setRotateGesturesEnabled(true);
        googleMap.getUiSettings().setAllGesturesEnabled(true);

    } catch (Exception e) {
        Log.e("TAG", "MSG: " + e);
    }

    return rootView;
}

private void initializeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();

        if (googleMap == null) {
            Toast.makeText(MapsFragment.this.getActivity(),
                    "Sorry! unable to create maps", Toast.LENGTH_LONG)
                    .show();
        }
    }
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));
    FragmentTransaction ft = getActivity().getFragmentManager()
            .beginTransaction();
    ft.remove(fragment);
    ft.commit();
}
}

有人可以帮忙吗？!谢谢。

public MapsFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    //Let the mapFragment draw itself and then you return this view later at the bottom.
    View mapView = super.onCreateView(inflater, container, savedInstanceState);


    /*View rootView = inflater.inflate(R.layout.fragment_maps, container,
            false);*/

    try {
        initializeMap();

        LatLng pos = new LatLng(latitude, longitude);
        MarkerOptions marker = new MarkerOptions()
                .position(pos)
                .title("Fishork")
                .icon(BitmapDescriptorFactory
                        .fromResource(R.drawable.marker));
        MarkerOptions marker1 = new MarkerOptions()
                .position(new LatLng(18.90370, 72.81314))
                .title("Zaffran")
                .icon(BitmapDescriptorFactory
                        .fromResource(R.drawable.marker));

        CircleOptions circle = new CircleOptions().center(pos).radius(2000)
                .strokeColor(Color.parseColor("#FFFFFF")).strokeWidth(5)
                .fillColor(Color.parseColor("#25f67f21"));

        CircleOptions circle1 = new CircleOptions()
                .center(new LatLng(18.90370, 72.81314)).radius(1000)
                .strokeColor(Color.parseColor("#FFFFFF")).strokeWidth(5)
                .fillColor(Color.parseColor("#25f67f21"));

        //Get instance to this googleMap
        googleMap = this.getMap();


        googleMap.addMarker(marker);
        googleMap.addMarker(marker1);
        googleMap.addCircle(circle);
        googleMap.addCircle(circle1);

        CameraPosition cp = new CameraPosition.Builder()
                .target(new LatLng(latitude, longitude)).zoom(10).build();
        googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cp));

        googleMap.setMyLocationEnabled(true);
        googleMap.getUiSettings().setZoomControlsEnabled(true);
        googleMap.getUiSettings().setMyLocationButtonEnabled(true);
        googleMap.getUiSettings().setCompassEnabled(true);
        googleMap.getUiSettings().setZoomGesturesEnabled(true);
        googleMap.getUiSettings().setRotateGesturesEnabled(true);
        googleMap.getUiSettings().setAllGesturesEnabled(true);

    } catch (Exception e) {
        Log.e("TAG", "MSG: " + e);
    }

    return mapView;
