单击Expandable ListView父组件，不打开子列表
[英]Click on Expandable ListView parent component not opening child list
问题描述
I make a Expandable list but when i click on parent but it not open child component and its close its. 
我做了一个可扩展列表，但是当我单击父级但它没有打开子级组件并关闭它时。 What is wrong happening i don't know. 我不知道发生了什么事。 If any one say i also provide snapshot. 如果有人说我也提供快照。 I tried many thing but nothing is happened. 我尝试了很多事情，但没有任何反应。 I thing all these happen bcoz adding scroll view before adding scroll view these work perfectly. 我觉得所有这些事情都发生了，因为在添加滚动视图之前，bcoz添加滚动视图可以完美地工作。 But not Its not working check my xml file if any error found please inform me. 但是，如果发现任何错误，请检查我的xml文件是否不起作用，请通知我。
