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:
 |  |  |  |
- Create a new project, name TabGroupChildDemo.
- Create an TabHostActivity and extend it to TabActivity.
- Create 3 other activity name-HomeActivity, AboutActivity, ContactActivity.
- Create 3 group activity name-HomeGroupActivity, AboutGroupActivity, ContactGroupActivity.
- Create an other Activity ChildActivity.java.
- Create 4 layout for Home, About, Contact, Child Activity, name activity_home, activity_about, activity_contact, activity_child.
- Create 3 other layout for display tabs- home_tab,about_tab,contact_tab.
- Add activity and group activity in manifest.xml
- Add images – home.png, about.png, contact.png, ic_tab_background in drawable folder, download below images
