[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。

  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

                        .getDecorView());
            }
        });
    }
}

    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。
