在FrameLayout中使用Fragment

• 存在两种情况，一个是getFragmentManager().beginTransaction().replace()替换，一个是add(),show(),hide()隐藏显示。两个调用的方法不同。

生命周期

• 第一次添加fragment

• 调用hide()方法

fragment内部回调该方法onHiddenChanged(boolean hidden)

• 调用replace()方法

• 在fragment中启动另一个activity

03-31 16:48:52.604: I/meme(9551): onPause:

• 返回原activity

03-31 16:48:48.349: I/meme(9551): onResume:

• activity销毁
