TabMenu本身就是一个PopupWindow,PopupWindow上面放了两个GridView,第一个GridView就是分页标签,位于PopupWindow的顶部,第二个GridView是菜单,位于PopupWindow的主体。为了实现PopupWindow的弹出/退出的动画效果,本文使用了以下代码:
在工程的res文件夹里添加anim子目录,再新建文件popup_enter.xml:
01.
02.
03.
04.
05.
新建文件popup_exit.xml:
01.
02.
03.
04.
05.
在工程的values文件夹里新建文件popup_animation.xml:
main.xml的源码如下:
01.
02.
04. xmlns:android="http://schemas.android.com/apk/res/android">
05.

TabMenu的封装类TabMenu.java的源码如下:
