ios如何快速转型安卓开发-专题3
1.Fragment
可以嵌入活动当中的UI片段。
1.碎片的通信
FragmentManager提供一个finViewById，专门从布局文件中获取碎片的实例
2.碎片的生命周期
1.状态
（1）运行状态：可见
（2）暂停状态：被覆盖但部分可见
（3）停止状态：完全不可见
（4）销毁状态：被移除
2.回调
（1）onAttach（）。碎片和活动建立关联。
（2）onCreateView（）。碎片创建视图时调用。
（3）onActivityCreated（）。确保与碎片相关联的活动一定已经创建完毕的时候调用。
（4）onDestory（）。当与碎片关联的视图被移除的时候调用。
（5）onDetach（）。当碎片与活动解除关联的时候调用。
3.动态加载布局
使用限定符匹配对应的平板和手机情况。
4.系统通知

2.Service
1.服务的生命周期
生命周期回调方法：
(1)onCreate()
(2)onStartCommand()
(3)onBind()
(4)onDestory
调用startService（）方法后，对应服务就会启动，并回调onStartCommand（）方法，服务没有创建，onCreate（）就会先于onStartCommand（）方法执行，调用stopService，unBindService方法，执行onDestory方法。
2.前后台服务

3.多线程
1.异步消息处理机制
异步消息处理：由四个部分组成，Message、Hanlder、MessageQueue、Looper。
（1）Message：线程之间传递消息，用于在不同线程之间交换数据。
（2）Handler：用于发送和处理消息，sendMessgae（），经过一系列的处理之后，传递到HandleMessgae中。
（3）MessageQueue：用于存放所有通过Handler发送的消息，每个线程只会有一个MessageQueue对象。
（4）Looper：每个线程中的MessageQueue的关机，调用Looper中的loop（）方法后，会进入到一个无限循环当中，发现MessageQueue中存在一条消息，就会将其取出，传递到HanleMessage方法中。每个线程中也只会有一个looper对象。
2.AsyncTask使用
重新其中方法可完成对应的任务调度
（1）onProExecute（）：在后台任务开始执行前调用，用于进行界面上的初始化操作。
（2）doInBackground(Params...):方法中所有代码都会在子线程中执行，不可以进行UI的操作
（3）onProgressUpdate(Progress...):后台调用了publishProgress(Progress...)方法后，此方法就会调用，返回的数据作为参数传递，可以进行Ui操作。
（4）onPostExecute(Result)：后台任务执行完毕之后，并执行return 返回时，调用此方法，返回数据作为参数传递到此方法中，可以利用返回数据做UI操作。
4.接入三方SDK实现and ServiceTest
