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,给用户一个操作反溃
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:
?<selector xmlns:android="http://schemas.android.com/apk/res/android"|~
android:exitFadeDuration="@android:integer/config_mediumAnimTime">|~

<!-- Even though these two point to the same resource, have two states so the drawable will invalidate itself when coming out of|~
pressed state. -->|~
