android LinearLayout等view如何获取button效果

我们可以给LinearLayout以及一切继承自View的控件，设置View.onClickListener监听，例如LInearLayout。

但是我们发现LinearLayout可以执行监听方法体，但是没有点击效果。

所谓的点击效果就是当我们用鼠标点击控件时，可以高亮或者动一下，给用户一个操作反馈。

如何给LinearLayout实现上述效果那，最简单的就是给LinearLayout配置上以下属性

style="?android:attr/actionButtonStyle" 

style="?android:attr/actionButtonStyle"

那么我们的按钮就具有了Button的样式效果。点击等操作和Button一样。

另外：我们也可以配置一个文件，在文件内配置上点击时图片效果，按下时图片效果等，例如：
