Java 如何将GoogleMapAPIv2包含到片段中？

这里是一个例子，我想在一个动作栏中添加一个GoogleAPI，该动作栏将指向一个片段。但是，它失败了，因为fragment类必须扩展FragmentActivity，而操作栏不允许它，有人可以帮助修复它吗？非常感谢

MainHome.java

package com.example.demo3;    
import android.app.ActionBar;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

public class MainHome extends Activity {    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainhome);

        initView();
    }


    private void initView() {

        final ActionBar actionBar = getActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        actionBar.setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE);

        actionBar.addTab(actionBar
                .newTab()
                .setText("My Information")
                .setTabListener(
                        new MyTabListener<FragmentPage1>(this,
                                FragmentPage1.class)));

        actionBar.addTab(actionBar
                .newTab()
                .setText("My Location")
                .setTabListener(
                        new MyTabListener<FragmentPage2>(this,
                                FragmentPage2.class)));
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.prelog, menu);
        return true;
    }
}

它带来了我需要扩展FragmentActivity以启用

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

。然而，这将使

actionBar.addTab(actionBar
                        .newTab()
                        .setText("My Location")
                        .setTabListener(
                                new MyTabListener<FragmentPage2>(this,
                                        FragmentPage2.class)));

actionBar.addTab（actionBar
.newTab（）
.setText（“我的位置”）
.SetTableListener(
新MyTabListener（此，
碎片（第2页，类别））；

失败了。谁能给点建议

使用mapview而不是像这样使用mapfragment

<com.google.android.gms.maps.MapView
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

public class MyMapFragment extends Fragment {

    private MapView mMapView;
    private GoogleMap mMap;
    private Bundle mBundle;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View inflatedView = inflater.inflate(R.layout.map_fragment, container, false);

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

        mMapView = (MapView) inflatedView.findViewById(R.id.map);
        mMapView.onCreate(mBundle);
        setUpMapIfNeeded(inflatedView);

        return inflatedView;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mBundle = savedInstanceState;
    }

    private void setUpMapIfNeeded(View inflatedView) {
        if (mMap == null) {
            mMap = ((MapView) inflatedView.findViewById(R.id.map)).getMap();
            if (mMap != null) {
                setUpMap();
            }
        }
    }

    private void setUpMap() {
        mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
    }

    @Override

        mMapView.onResume();
