没有得到ListView的OnItemClick事件

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // 在这里处理点击事件，例如获取被点击的数据项
        String item = (String) parent.getItemAtPosition(position);
        Toast.makeText(getApplicationContext(), "点击了：" + item, Toast.LENGTH_SHORT).show();
    }
});
