如何处理的Andr​​oid SimpleExpandableListAdapter项选择 [英] How to handle Android SimpleExpandableListAdapter entry selection

问题描述

我在使用SimpleExpandableListAdapter类型的Andr​​oid应用程序创建可扩展列表。
但我完全茫然，我怎么检测活动时，已经选择了子项之一/点击。

I have created an expandable list in my Android application using the SimpleExpandableListAdapter type. But I'm at a complete loss as to how I detect events when one of the child entries has been selected/clicked.

我已经尝试了所有常用的OnClickListener / OnChildClickListener等，但似乎无法找到（通过实验，或一个小时的谷歌搜索一半）正确的处理程序应该是什么。

I've tried all the usual OnClickListener/OnChildClickListener etc, but can't seem to find (by experimentation, or half an hour googling) what the correct handler routines should be.

任何帮助greatfully AP preciated。

Any help greatfully appreciated.

推荐答案

它应该是：

list.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
    public void onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
        Object o = (Object)adapter.getChild(groupPosition, childPosition);
        // perform work on child object here
    }
}  

虽然，这听起来像你尝试过这... <一个href=\"http://developer.android.com/reference/android/widget/ExpandableListView.OnChildClickListener.html\"相对=nofollow> ExpandableListView.OnChildClickListener 说，这是，其实办法做到这一点。

Though, it sounds like you tried this... ExpandableListView.OnChildClickListener says that it is, in fact, the way to do it.

另外，你定义的方法allItemsAreEnabled（）和/或isEnabled（）为您ListAdapter？你不应该有，但也许他们目前定义并返回错误的值？

Also, have you defined the methods allItemsAreEnabled() and/or isEnabled() for your ListAdapter? You shouldn't have to, but maybe they are currently defined and returning the wrong values?
