我正在使用选项卡式布局(使用滑动).这里我有3个选项卡,由SectionsPagerAdapter控制.每个选项卡都是一个ListFragment.

现在,我希望在单击列表中的某个项目时触发事件.我希望每个标签都有一个监听器.

这是现在的代码(哪个不起作用,事件不会被触发).

public class NyhederFragment extends ListFragment {
     public static final String ARG_SECTION_NUMBER = "section_number";
     private static final String TAG="NyhederFragment";
     private List<Item> newsItems;
     private ArrayList newsHeadlines;
     private ArrayAdapter adapter;
     private BroadcastReceiver updateReciever;

public NyhederFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    ListView newsList = new ListView(getActivity());
    newsList.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
    newsList.setId(R.id.list);
    DatabaseHelper dbConn = new DatabaseHelper(getActivity());

    newsItems = dbConn.getAllItemsFromNews();
    newsHeadlines = new ArrayList();
    for(Item i : newsItems){
        newsHeadlines.add(i.getTitle());
    }

    adapter = new ArrayAdapter(getActivity(), android.R.layout.simple_list_item_1, newsHeadlines); …

在Zwitscher,我有一个ListView显示一些推文.然后用户可以重新加载时间线,如果有新的推文,新列表将加载到列表适配器(加上一些旧的),然后我滚动到列表的末尾

listView.setSelection(x); 

x新装载的最早推文的数量在哪里.这非常有效.但不幸的是这种"禁止"的onItemClick(),并onItemLongClick()在视图处理程序.如果我然后(例如从一个按钮)打电话

listView.setSelection(0);

处理程序onItemClick()和onItemLongClick()再次"启用".

我已经验证了调用后仍然在listView上设置处理程序setSelection(x).禁用该调用setSelection(x)也不会"禁用"处理程序.

知道我做错了什么吗？

我有一个显示有关玩家信息的活动.这部分工作正常.(我使用了适配器).但是,我应该在哪里放置检测单击行的代码？

PlayersActivity.java

package com.democratandchronicle.billstrainingcamp;

import android.os.Bundle;

public class PlayersActivity extends ListActivity 
{

    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_players);
        PlayersAdapter adapter = new PlayersAdapter(this);
        getListView().setAdapter(adapter);
        PlayersFetchTask loadPlayersTask = new PlayersFetchTask(adapter);
        loadPlayersTask.execute(); 
    }
}

PlayersAdapter.java
