如何在可扩展列表中为儿童创建点击事件 [英] How to create on click event for children in Expandable list

问题描述

我正在玩这个例子。
http：/ /developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList2.html

我无法想象了解如何将侦听器附加到子元素，以便在用户点击电话号码时触发一些操作。

任何代码或链接都将不胜感激。

解决方案

您需要订阅 setOnChildClickListener

  getExpandableListView（）。setOnChildClickListener（this）; 
  

并实现OnChildClickListener

  @Override 
 public boolean onChildClick（ExpandableListView parent，View v，int groupPosition，
 int childPosition，long id）{
 //使用groupPosition和childPosition找到当前适配器中的项
返回true; 
} 
  

I am playing around with this example. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList2.html

I cannot figure out how to attach a listener to the children elements so that I can trigger some action when the user taps on the phone number.

Any code or links would be greatly appreciated.

解决方案

You need to subscribe to setOnChildClickListener

getExpandableListView().setOnChildClickListener(this);

and implement OnChildClickListener

@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition,
        int childPosition, long id) {
    // use groupPosition and childPosition to locate the current item in the adapter
    return true;
}
