我正在尝试在 fragment 中的 viewpager (fragmentpager) 中使用 google maps v2。如果我滑动到第四个 fragment (查看寻呼机)，它工作正常，但如果我回到第一个 fragment ，然后回到第四个 fragment - 使用 map - 我的应用程序死了。

安卓Java:

public class LocationDetail extends Fragment {

private SupportMapFragment mMapFragment;
private GoogleMap map;
private EventAdapter listAdapter ;

protected MainActivity activity;

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

    View vw = inflater.inflate(R.layout.map, container, false);

    try {
        MapsInitializer.initialize(getActivity());
    } catch (GooglePlayServicesNotAvailableException e) {
        // TODO handle this situation
    }

    map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map_container)).getMap();
    map.setMyLocationEnabled(true);


    map.addMarker(new MarkerOptions()
    .position(new LatLng(48.397141, 9.98787)).title(" Theatro Club Ulm"));

    map.moveCamera( CameraUpdateFactory.newLatLngZoom(new LatLng(48.397141, 9.98787) , 14.0f) );

    return vw;
}

}

布局:

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

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1.0"
android:orientation="vertical" >

 <fragment

    android:id="@+id/map_container"
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.dr.diskoapp.MainActivity"
    />
</LinearLayout>

<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1.0"
android:orientation="vertical" >

<ListView 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/list">          
</ListView>
</LinearLayout>
</LinearLayout>

我看到有很多线程有类似的问题，但没有解决方案:-/

这次也许有人可以帮忙。

------------ 编辑 ----- 我找到了解决方案:-)

public void onDestroyView() {
    super.onDestroyView();

    try {
        Fragment fragment = (getFragmentManager().findFragmentById(R.id.map_container));  
        FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.remove(fragment);
        ft.commit();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

最佳答案

public void onDestroyView() {
super.onDestroyView();

try {
    Fragment fragment = (getFragmentManager().findFragmentById(R.id.map_container));  
    FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
    ft.remove(fragment);
    ft.commit();
} catch (Exception e) {
    e.printStackTrace();
}
