Tab1：点击时应显示某个地方的一些细节.
Tab2：点击后应显示地图.

我正在使用Fragments.

我的tablistener：

private class MyTabListener implements ActionBar.TabListener {
        @Override
        public void onTabSelected(Tab tab,android.support.v4.app.FragmentTransaction ft) {
            // TODO Auto-generated method stub
            if (tab.getPosition() == 0) {
                DetailsFragment fragment = new DetailsFragment();
                ft.replace(android.R.id.content,fragment);

            } else {
                MapsFragment fragment = new MapsFragment();
                ft.replace(android.R.id.content,fragment);
                //ft.commit();
            }
        }

MapsFragment.java

public class MapsFragment extends MapFragment {

    private MapView map = null;
    private MyLocationOverlay me = null;

    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
        return (new FrameLayout(getActivity()));
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        map = new MapView(getActivity(),"0rQAS47Cicu2t7z4w8Ev6A6de7QlbjvKyi8I-QQ");
        map.setClickable(true);

        map.getController().setCenter(
                getPoint(40.76793169992044,-73.98180484771729));
        map.getController().setZoom(17);
        map.setBuiltInZoomControls(true);

        Drawable marker = getResources().getDrawable(R.drawable.marker);

        marker.setBounds(0,marker.getIntrinsicWidth(),marker.getIntrinsicHeight());

        map.getOverlays().add(new SitesOverlay(marker));

        me = new MyLocationOverlay(getActivity(),map);
        map.getOverlays().add(me);

        ((ViewGroup) getView()).addView(map);
    }

    @Override
    public void onResume() {
        super.onResume();

        me.enableCompass();
    }

    @Override
    public void onPause() {
        super.onPause();

        me.disableCompass();
    }

    private GeoPoint getPoint(double lat,double lon) {
        return (new GeoPoint((int) (lat * 1000000.0),(int) (lon * 1000000.0)));
    }

    private class SitesOverlay extends ItemizedOverlay<OverlayItem> {
        private List<OverlayItem> items = new ArrayList<OverlayItem>();

        public SitesOverlay(Drawable marker) {
            super(marker);

            boundCenterBottom(marker);

            items.add(new OverlayItem(getPoint(40.748963847316034,-73.96807193756104),"UN","United Nations"));
            items.add(new OverlayItem(getPoint(40.76866299974387,-73.98268461227417),"Lincoln Center","Home of Jazz at Lincoln Center"));
            items.add(new OverlayItem(getPoint(40.765136435316755,-73.97989511489868),"Carnegie Hall","Where you go with practice,practice,practice"));
            items.add(new OverlayItem(getPoint(40.70686417491799,-74.01572942733765),"The Downtown Club","Original home of the Heisman Trophy"));

            populate();
        }

        @Override
        protected OverlayItem createItem(int i) {
            return (items.get(i));
        }

        @Override
        protected boolean onTap(int i) {
            Toast.makeText(getActivity(),items.get(i).getSnippet(),Toast.LENGTH_SHORT).show();

            return (true);
        }

        @Override
        public int size() {
            return (items.size());
        }
    }
}

问题是当我点击地图标签时出现第一次地图.但是,我转到详细信息选项卡,然后再次返回到地图选项卡,我的应用程序崩溃并出现错误：

问题是什么.我知道MapView不能从片段中膨胀.但我使用这种技术：

但这仍然不起作用.我需要一些帮助.
