Android Child Group Activity | Android TabActivity | Tab Host Activity Example in Android | Activity inside Activity in Android | Animated Activity in Android

Hello Friends,
 Today I am going to share very Important post for Child Group Activity, means activity open inside Tab Group. For this I use Animated Activity. This logic I picked from stackoverflow.com. Hope it will help some one.

Print Screen:

1)Create a new project, name TabGroupChildDemo.

2)Create an  TabHostActivity and extend it to TabActivity.

3)Create 3 other activity name-HomeActivity, AboutActivity, ContactActivity.

4)Create 3 group activity name-HomeGroupActivity, AboutGroupActivity, ContactGroupActivity.

5)Create an other Activity ChildActivity.java.

6)Create 4 layout for Home, About, Contact, Child Activity, name activity_home, activity_about, activity_contact, activity_child.

7)Create 3 other layout for display tabs- home_tab,about_tab,contact_tab.

8)Add activity and group activity in manifest.xml

9)7)Add images - home.png, about.png, contact.png,ic_tab_background in drawable folder, download below images-

 My Code:
