想了解activitygroup 切换动画效果怎样实现的相关内容吗，在本文为您仔细讲解activitygroup 切换动画效果的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：activitygroup,切换动画，下面大家一起来学习吧。
**一下提供伪代码，仅说明自己的理解，思路**/
/*************************************************/
/*假设*/
AActivity,BActivity,CActivity,DActivity 都extends ActivityGroup.
A1Activity,B1Activity,C1Activity,D1Activity 都extends Activity.
A2Activity,B2Activity,C2Activity,D2Activity 都extends Activity
/*一，AActivity继承了Activity，调用startActivity()的时候会在tab内部contentView显示A1Activity*/
AActivity.this.startActivity(A1Activity.class)
BActivity.this.startActivity(B1Activity.class)
CActivity.this.startActivity(C1Activity.class)
DActivity.this.startActivity(D1Activity.class)
/*二，A1Activity没有继承ActivityGroup，所以调用startActivity()的时候和普通的调用没有区别，A2会填满窗口*/
A1Activity.this.startActivity(A2Activity.class)
B1Activity.this.startActivity(B2Activity.class)
C1Activity.this.startActivity(C2Activity.class)
D1Activity.this.startActivity(D2Activity.class)
/*三，A1Activity.this.getParent()获得的是AActivity, 其实就是ActivityGroup； 虽然A1Activity没有继承ActivityGroup，但是A2Activity实际是由A1Activity的父类AActivity启动的,所以A2Activity的启动效果和一差不多*/
A1Activity.this.getParent().startActivity(A2Activity.class)
B1Activity.this.getParent().startActivity(B2Activity.class)
C1Activity.this.getParent().startActivity(C2Activity.class)
D1Activity.this.getParent().startActivity(D2Activity.class)
