There are a number of ways of doing this.
有多种方法可以做到这一点。
The simplest way of doing this is by playing around with various Viewattributes such as android:focusable, android:focusableInTouchMode, android:clickable, and TextViewattributes such as android:selectAllOnFocus.
这样做的最简单的方法是通过玩弄各种查看属性，例如android:focusable，android:focusableInTouchMode，android:clickable，和TextView的属性，例如android:selectAllOnFocus。
You could also customize the appearance of your views by setting their backgrounds to StateListDrawables (a.k.a. <selector>drawables).
您还可以通过将视图的背景设置为StateListDrawables（又名<selector>可绘制对象）来自定义视图的外观。
