本文介绍了setOnItemClickListener不工作在列表视图的android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
我想通过点击其上的列表视图加载列表项移动到其他活动，但我不为什么它没有移动到任何其他活动时，我点击任何一个列表项什么也没有发生任何碰撞，没有移动到其他活动无关。可在任何一帮我请。
我搜索很多，有这么多的解决方案，但任何解决方案的不工作在我的情况。请在下面帮我活动code。

解决方案
问题是，Android不允许您选择有是可聚焦在他们身上的元素列表中的项目。我修改的列表项的复选框有像这样的属性：
机器人：可调焦=假
机器人：focusableInTouchMode =假
现在我的包含复选框（作品按钮太）是传统意义上的选择列表项（它们亮起来，你可以任意位置单击列表中的项目和onListItemClick处理程序会火，等等）。
I am trying to move to other activity by clicking on list item which is loaded in list-view, but i don't why it is not moving to any other activity when i click on any list item nothing happens no crash, not moving to other activity nothing. Can any-one help me please.

解决方案
The issue is that Android doesn't allow you to select list items that have elements on them that are focusable. I modified the checkbox on the list item to have an attribute like so:
android:focusable="false"
android:focusableInTouchMode="false"
Now my list items that contain checkboxes (works for buttons too) are "selectable" in the traditional sense (they light up, you can click anywhere in the list item and the "onListItemClick" handler will fire, etc).
这篇关于setOnItemClickListener不工作在列表视图的android的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
