Question

在我的应用程序中有一个SherlockFragmentActivity，其中有6个片段。其中一个片段包含map-fragment。

问题：现在问题是当我启动应用程序时地图加载成功，但是当我转到其他片段然后再次尝试加载map-fragment时，它不会加载并给出错误。< / p>

我还试图删除视图，但它也无法正常工作

这是我的代码，

public class SearchMapFragment extends SherlockFragment implements
        OnMyLocationButtonClickListener, ConnectionCallbacks,
        OnConnectionFailedListener, LocationListener,
        OnInfoWindowClickListener, OnMarkerClickListener, OnMapClickListener {

    private static View mView;
    private GoogleMap mMap;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        if(mView != null){
            ((ViewGroup)mView.getParent()).removeAllViews();
        }

        mView = inflater.inflate(R.layout.fragment_search_map, null);   

        if (mMap == null) {

            mf = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.fragment_searchMap);

            mMap = mf.getMap();
        }   

        return mView;
    }

}

这是我的LogCat，

Answer 1

您错误地将SupportMapFragment添加到您的片段中。

请阅读nested fragments。

当嵌套碎片记住这些东西时：

使用getChildFragmentManager，
不要在xml中添加SupportMapFragment。

包含SupportMapFragment的SherlockFragment不会第二次打开
