android - 在 ActionBarSherlock 中覆盖 onContextItemSelected()

Question

我有一个扩展 SherlockActivity 的类，因为我在 Activity 中使用了 ActionBarSherlock 操作栏。但是，我还尝试将上下文菜单添加到此 Activity 中的 ListView ，该 Activity 在长按 ListView 中的项目时启动。我在 onContextItemSelected(MenuItem item) 声明中遇到错误，表明我的覆盖无效，因为没有可覆盖的内容。但是，当我删除覆盖时，该函数永远不会被调用。我知道这与 SherlockActivity 从 Activity 继承的方式有关，但我不确定具体细节。也许我缺少进口？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;
}
}

这是我为该类(class)导入的所有内容:

import java.util.ArrayList;

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

import android.app.Activity;
import android.app.PendingIntent;
import android.app.PendingIntent.CanceledException;
import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.text.Html;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;

很久以前遇到过类似的问题，我通过强制普通 MenuItem 使用其完全限定的类名 (android. view.MenuItem)，像这样:

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