我使用的可扩展列表视图按南,北,东,centeral.States列表显示一样,显示印度的状态,但是当申请onChildclickListener到expandableListView没有response.I希望在印度的点击状态,一个新的活动开放。

解决方案
这个问题出现那么你的孩子的看法有自己的聚焦元素。您可以通过删除机器人将其删除:点击儿童布局,或设置为false:
< XML版本=1.0编码=UTF-8&GT?;
< LinearLayout中的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =FILL_PARENT
机器人:layout_height =WRAP_CONTENT
机器人:背景=@可绘制/ group_item_normal
机器人:ID =@ + ID / groupItem
<! - 从这里删除点击 - >
< - 或者Android!点击=假 - >
>
如果您的孩子元素不具有任何可以点击的,可聚焦的元素,然后工作非标准的ListView可获得焦点。

解决方案
This issue appear then your children's View has own focusable element. You can remove it by removing android:clickable from children layout or set to false:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/group_item_normal"
android:id="@+id/groupItem"
<!-- remove clickable from here -->
<!-- or android:clickable="false" -->
>
If you children element doesn't has any clickable and focusable elements, then work standart ListView focusable.
sorry for my bad english
