安卓OnItemClickListener

Question

我有一台连接了适配器的ListActivity。现在，我想在适配器中注册单击列表项。这是我在ListActivity的onCreate中的解决方案：

        this.myList = getListView();
        this.myList.setAdapter(this.adapter);
        this.myList.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                Log.d("Click", "ListView");
            }
        });

但是OnItemClickListener永远不会响应。怎么啦？

Answer 1

ListView list = (ListView) findViewById(R.id.listView1);

 MobileArrayAdapter adapter = new MobileArrayAdapter(this,android.R.layout.simple_list_item_1);
 list.setAdapter(adapter);       

 list.setOnItemClickListener(new OnItemClickListener() {
 public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
 //your data

     }
}   

Answer 2

您不需要设置OnItemClickListener。您必须覆盖onListItemClick

@Override 
    public void onListItemClick(ListView l, View v, int position, long id) {
        // Do something when a list item is clicked
    }

第三个参数position是适配器中position处的元素。

Answer 3

如果您使用每个列表项都有行布局，而不是在每个ImageView、按钮、复选框或TextView等的行布局中...您必须在xml中添加此行

 android:clikable="false"
 android:focusable="false"
