ListFragment OnListItemClick不会被调用 [英] ListFragment OnListItemClick not being called
本文介绍了ListFragment OnListItemClick不会被调用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个扩展ListFragment一个类，它覆盖OnListItemClick方法。我也是这样做的另一个ListFragment同样的方法（该方法被调用）。我很奇怪，为什么该方法不会被调用，当我点击列表项？
I have a class that extends ListFragment, and it overrides the OnListItemClick method. I am also doing this in another ListFragment the same way (and the method gets called). I am wondering why the method does not get called when I click on the list item?

任何帮助将是非常美联社preciated。我可以得到想要的效果通过实施一些其他的侦听器，并将其分配给每个项目，但我认为这是做了正确的方式，它应该工作。我只是不知道为什么它没有
Any assistance would be much appreciated. I can get the desired effect by implementing a few other listeners and assigning it to each list item, but I think this is the correct way to do it and it SHOULD work. I just don't know why it doesn't
在此先感谢。
推荐答案
如果你在你的布局一个项目，可以从其他组件，如一个CheckBox偷输入，该组件需要被定义为不可作为焦点。
If you have an item in your layout that can steal input from other components like a CheckBox, that component needs to be defined as not focusable.
