效果如下:
具体实现如下:
文件名为:guide_go_button.xml
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="false" android:state_pressed="false" android:drawable="@drawable/guide_btn_red" />
<item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/guide_btn_red_pressed" />
<item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/guide_btn_red_pressed" />
<item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/guide_btn_red_pressed" />
</selector>
把这个selector作为图片设置为Button的背景即可。
