How to change the title of the Tab Dynamically

Question

I have three tabs in my Application. On an event under one Tab, i want to change the title of an another existing Tab. This is the title that we provide while adding the tab

Answer 1

Unless you can find a cleaner method, you can access the TabWidget itself. Contained in the TabWidget are relative layouts for each of your tabs which each contain an ImageView and a TextView. To directly access the textview in the tab at index 0 you can do this:

mTabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title);

Then just cast as a TextView and you can edit it however you want. The below worked for me:

((TextView)mTabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title)).setText("New");

Answer 2

Rather than setting the indicator as a String, use one where you set the View to be used. Then, you can hold onto that View (e.g., a TextView) and change its contents as needed.

Answer 3

You should not use anymore "TabHost" for ICS, it has been deprecated in version 13. instead you need to you "ActionBar"...

Tab mTab = super.getSupportActionBar().getTabAt(0); 
mTab.setText("new Title");

Android will refresh the tab right away
