  Android: How to fire onListItemClick in Listactivity with buttons in list?

我已经开发了一个应用程序,其中我已经制作 ListActivity ,其中客户列表视图将显示自定义项目列表。所有事情都很顺利但在这里我对itemOnClickListner感到困惑。如何在listActivity中添加onclick listner?因为没有任何listview初始化,我可以通过listview控件设置列表器...我从here找到了但它也不适合我

:这是Code ::

在list活动中使用getListview()获取List ..........

在Oncreate中

 ListView lv = getListView();

http://www.mkyong.com/android/android-listview-example/

此链接有两种方式

1- overriding  onListItemClick(
2- Setting you listener.. 

答案 1 :(得分:0)

试试这种方式..

ListView lv = getListView();
lv. storelist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {
}
}

这对你有帮助。

为此重写onlistitemclick()函数。这里整数位置表示您按下的项目的位置

@Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        super.onListItemClick(l, v, position, id);
        .......
    }

答案 3 :(得分:0)

试试这个

getListView().setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position,
                    long arg3) {
                // TODO Auto-generated method stub

            }
        });
