Activity转化成View

1.LocaActivityManager am = new LocalActivityManager(Context,true);

2.Window window = am.startActivity("tag",new Intent());

3.View view = window.getDecorView();

接下来一定要在3个生命周期函数里调用如下方法，否则会抛出异常：java.lang.IllegalStateException: Activities can‘t be added until the containing group has been created.

onCreate()方法里调用am.dispatchCreate(savedInstanceState);

onPause()方法里调用am.dispatchPause(true);

onResume()方法里调用am.dispatchResume();
