我正在尝试将地图视图附加到选项卡中的片段。

这是我的 MapFragment：

import android.app.LocalActivityManager;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;

import com.actionbarsherlock.app.SherlockFragment;

public class MapFragment extends SherlockFragment {
    private static final String KEY_STATE_BUNDLE = "localActivityManagerState";

    private LocalActivityManager mLocalActivityManager;

    protected LocalActivityManager getLocalActivityManager() {
        return mLocalActivityManager;
    }

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

        Bundle state = null;
        if (savedInstanceState != null) {
            state = savedInstanceState.getBundle(KEY_STATE_BUNDLE);
        }

        mLocalActivityManager = new LocalActivityManager(getActivity(), true);
        mLocalActivityManager.dispatchCreate(state);
    }

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
            //This is where you specify you activity class
        Intent i = new Intent(getActivity(), LocationActivity.class); 
        Window w = mLocalActivityManager.startActivity("tag", i); 
        View currentView=w.getDecorView(); 
        currentView.setVisibility(View.VISIBLE); 
        currentView.setFocusableInTouchMode(true); 
        ((ViewGroup) currentView).setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
        return currentView;
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putBundle(KEY_STATE_BUNDLE,
                mLocalActivityManager.saveInstanceState());
    }

    @Override
    public void onResume() {
        super.onResume();
        mLocalActivityManager.dispatchResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mLocalActivityManager.dispatchPause(getActivity().isFinishing());
    }

    @Override
    public void onStop() {
        super.onStop();
        mLocalActivityManager.dispatchStop();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mLocalActivityManager.dispatchDestroy(getActivity().isFinishing());
    }
}

这是我的位置活动：

          }
        });



      expandListButton.setText("Searching..");
  }

只是无法将其附加到片段。我哪里错了？

另外，这是最好的方法吗？我不能将它附加到片段本身而不是调用另一个活动吗？如果是这样，怎么做？

我相信SherlockMapActivityextendsMapActivity没有ActionBar

无论您在做什么，我都强烈建议您查看Android版Maps 的第 2 版并改用它。

我也认为SherlockMapActivity已从 ABS 中删除。（来源）
