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:

1)TabHostActivity.java

  1. I've bookmarked this for my future reference. I think I like the way that you have set up your tabs, over the way I have been doing (I've been using AndroidHive's tutorials for the tabactivity). But I guess your way makes a lot more sense to me as a person.

  2. TabActivity has been deprecated for a long time. Also, bottom tabs are inappropriate on Android.

    1. Yes you are right we can use action bar, pager, menu etc. But some time really we need these things on client demand. And I always write my problems and experience so when I will work on Action bar then sure I will publish.

    1. Hi Dileep, what you want to do exactly?
      1) suppose you are on child activity and you press android hardware home button, that mean activity running in background, so if you open again it it should open child activity.
      2)If you go out using android hardware back button then ofcourse it will destroy your app and will start from home tab.
      3)if you want open another tab every time you can set it. but this is not possible i.e.- you leave from which tab its start from there. for that case you should get current tab when you leave your application and on launch override your tab preference.

  16. It is a really useful tutorial. Thanks. Even I have to use Tabhost and bottom tabs because of client's demand. I have one question though. I want to display back button on the action bar for child activity inside the ActivityGroup. How is that possible?

    1. when you download any code from git-hub don't import just got through file menu in eclipse and then choose new option and after that from android option choose android project from existing code.
