我在 Listview 中使用 gridview，但我有一个可聚焦的问题。
我已经设置了gridview的宽度，但是我填充了gridview的一些项目，在gridview的左边空间(空白)意味着项目没有填充listview中的gridview。如果我点击它，它不会执行列表项点击
如图所示，如果在列表项的任何位置单击它，我想执行 ListView 项单击。我想获得列表项点击。
但是当我点击 ListView 项时，即 GridView 然后 ListItem 点击不起作用...

最佳答案
您可能已经解决了它，但我有另一个可能对某人有帮助的解决方案。
在 list_cell 的根布局中使用 android:descendantFocusability="beforeDescendants" XML .
关于android - Gridview 单击在自定义 ListView 中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17964795/
