android - 将事件监听器添加到 listView

Question

getSherlockActivity().findViewById(android.R.id.list);
new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView <? > arg0, View arg1, int position,
        long id) {
        // TODO Auto-generated method stub
        Toast.makeText(getSherlockActivity(), 
             "You selected :", Toast.LENGTH_SHORT).show();
    }
};

我正在尝试向我的 Activity 添加一个事件监听器，但 toast 消息根本没有显示。我从 onCreateView 方法中调用这段代码

看起来您实际上并没有在列表中设置点击监听器，您只是在创建它，甚至没有保留对它的引用。

像这样尝试:

ListView lv = (ListView)(getSherlockActivity().findViewById(android.R.id.list));
lv.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView <? > arg0, View arg1, int position,
        long id) {
        // TODO Auto-generated method stub
        Toast.makeText(getSherlockActivity(), 
             "You selected :", Toast.LENGTH_SHORT).show();
    }
});
