关于Android ListView无法触发ItemClick事件的问题

由于在ListView的item中加入了按钮导致了无法触发ListView的ItemClick事件,在网上搜罗了下,找到了原因和解决办法:

如果自定义的ListViewItem中有Button或者Checkable的子类控件的话,那么默认focus是交给了子控件,而ListView的Item能被选中的基础是它能获取Focus,也就是说我们可以通过将ListView中Item中包含的所有控件的focusable属性设置为false,这样的话ListView的Item自动获得了Focus的权限,也就可以被选中了,也就会响应onItemClickListener中的onItemClick()方法,然而将ListView的Item Layout的子控件focusable属性设置为false有点繁琐,其实还可以通过对Item Layout的根控件设置其android:descendantFocusability=”blocksDescendant”即可(子孙的Focus能力).

 

上面解决了如何让ItemClick事件生效,但是问题又来了,我尝试着给Item中的按钮添加事件监听,但是似乎没地方给它加监听呢,看来得在写篇文章探讨下了。
