bt_vote这个Button，第一次点没反应，大概是没获取到焦点，请问怎么解决

#4

帮忙顶顶

#5

改成onClick来试试。

#6

在父布局上加这个属性试试        android:descendantFocusability=""   

有三个属性：

#7

正常来说是不可能的。
看看你的点击事件怎么写的，代码贴出来。

#8

我估计是其他控件持有了焦点

点击事件是对的。你有给button设置吗？
设置了之后，建议吧你的事件中的代码换成简单的吐司，看看有没有。如果有的话，就是你点击事件的逻辑的问题了、。

这个是父控件在子控件之前拿到焦点，应该用afterDescendants
