I don't know how to do that in android. Can it be done?

查看按钮:

<Button 
  android:id="@+id/b8"

推荐答案

您需要使用所谓的 selector.

您可以从本网站阅读有关它们的信息并获取教程.

请记住，Android 中确实没有悬停"的概念，因为您无法将手指悬停在显示屏上.但是您可以创建选择器，例如，当按钮具有焦点时.通常一个按钮可以有三种状态:正常、聚焦和按下.

Keep in mind that there really isn't a concept in Android as "hover" since you can't hover your finger over the display. But you can create selectors for, say, when a button has focus. Normally a button can have three states: Normal, Focused and Pressed.
