activity管理类 appManager

时间:2023-12-12 20:59:20

程序启动第一个界面类: net.oschina.app.AppStart
功能描述:一张图片
代码细节描述:一个透明度的动画效果,效果动画完成后自动启动新的Activity(Main)

基本BaseActivity类,继承自Activity
功能描述:分别在onCreate方法中添加Activity到栈 ; 在onDestroy方法中移除Activity
代码细节描述: 提供了一个单例类AppManager,把创建的Activity放入到栈中进行管理,提供添加Activity , 移除当前Activity , 移除指定的Activity , 移除所有的Activity ,获得当前的Activity , 退出程序。 这个工具类非常适合与用作开发使用,具体代码如下:

仿Activity管理写的Fragment管理
