Can't change indicator colour for FragmentTabHost tabs

Question

I would like to implement a custom FragmentTabHost in my app. Documentation is limited on this subject, and I am unable to get it to work with my custom indicator drawables (green), they won't show up under the tab buttons.

I get only the default blue indicator. What can be wrong? Thanks.

Answer 1

i had a problem like this and i solved it with this code statement :

mTabHost.getTabWidget().getChildAt(mTabHost.getCurrentTab()).setBackgroundResource(R.drawable.tab_selected);

Good luck!
