在ActionBarSherlock中覆盖onContextItemSelected()

Question

我有一个扩展SherlockActivity的类,因为我在活动中使用了ActionBarSherlock操作栏.但是,我还尝试向此活动中的列表视图添加上下文菜单,该列表视图在列表视图中的项目被长按时启动.我在声明中遇到错误onContextItemSelected(MenuItem item),说我的覆盖无效,因为没有什么可以覆盖.但是,当我删除覆盖时,永远不会调用该函数.我知道这与SherlockActivity从Activity继承的方式有关,但我不确定具体细节.也许我错过了一个导入？请在此处查看相关代码:

public class Inbox extends SherlockActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_inbox);
    refreshMsgs(this.getCurrentFocus());
}

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    if (v.getId() == R.id.lstInbox){
        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
        String contactName = lstConversation.get(info.position).getContactName();   
        menu.setHeaderTitle(contactName);
        menu.add(Menu.NONE, 0, 0, "View contact");
        menu.add(Menu.NONE, 1, 1, "Delete thread");
    }
}

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
    SmsConversation selectedConvo = lstConversation.get(info.position);         

    if (item.getItemId() == 0){
        //view contact
        Intent viewcontactIntent = new Intent();
        String contactId = selectedConvo.getContactId();
        Uri uriContact = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, contactId);
        viewcontactIntent.setData(uriContact);
        PendingIntent pViewIntent = PendingIntent.getActivity(getBaseContext(), 1, viewcontactIntent, 0);
        try {
            pViewIntent.send();
        } catch (CanceledException e) {
            e.printStackTrace();
        }
    } else {
      //DELETE thread
    }
    return true;
}
}

以下是我对该课程的所有导入:

import java.util.ArrayList;

import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuItem;

很久以前面对类似的问题,我onContextItemSelected()通过MenuItem使用其完全限定的类名(android.view.MenuItem)强制正常来覆盖,如下所示:

@Override
public boolean onContextItemSelected (android.view.MenuItem item)
{
  //implementation
}
