这可以吗？
@Override
protected void onPostExecute(final ChannelPair p) {
HiddenChannelsListAdapter adapter = new HiddenChannelsListAdapter(p.ctx, p.channelList);
p.lv.setAdapter(adapter);
p.lv.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Log.i("CLICKED ON LV ITEM", "YEA");
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
它实际上并没有触发我认为的事件。至少没有项目被选中？
更新
所以我从 asyncTask 中删除了这些东西并将其添加到一个新线程中，所以现在它们都在同一个文件中。但是，我仍然无法从项目中获得点击次数

这部分是点击绑定的地方：
((Activity)ctx).runOnUiThread(new Runnable() {
public void run() {
HiddenChannelsListAdapter adapter = new HiddenChannelsListAdapter(ctx, channelList);
ListView lv = (ListView) vw.findViewById(R.id.list);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
{
Log.i("CLICKED ON LV ITEM", "YEA");
}
});
}
});
