[Android]使用ActivityGroup来切换Activity和Layout
前言
在一个主界面中做Activity切换一般都会用TabActivity,使用方便,Activity互相之间相对独立,但是可定制性不强,而且修改起来很麻烦。当然也可以把layout分开,把逻辑代码全写在主界面的逻辑代码中,但是很明显可维护性相当差,这里通过ActivityGroup来解决这个问题。

1. Android: TabActivity Nested Activities
2. Android ActivityGroup的使用代码将子activty 的layout加入到主activity中
正文
一、效果图
要求点击底部不同图片按钮切换不同的Activity,并在中间显示Activity对应的ContentView。
二、 实现代码
2.1 layout.xml

代码说明:
a). ModuleView1、ModuleView2、 ModuleView3分别继承自Activity。
b). 想动态改变标题可以通过cust_title获取TextView进行设置。
