Answer 1

Ok I think it's bug on android design support library v22.

Because You are talking about the changes in content but I can't change the color of Text. Once the tab are created and if you change the layout it will not reflecting.

And As i have seen your code you are giving the custom layout using setCustomView. and for changing a text you are calling again the method setTabView(). Instead of that there should be method getCustomView() so that you can change the layout. There is a method in a TabLayout.Tab.getCustomView but it doesn't have identifier and I have report this bug.

Finally bug is accepted by android bug source traking and marked as Future Release . So we can say that bug will no more exist on future library. and we can have method getCustomView() so that we can easily get our custom view.

Finally the bug is resolved Released in the v23 support libs . Just update support library using SDK manager and you have getCustomView() as a public.

just change this line in gradle

compile 'com.android.support:design:23.0.0'

and make sure compile and target sdk set to 23.

please check my code working fine for me

TabLayout.Tab tab=tabLayout.getTabAt(position);         
View view=tab.getCustomView();         
TextView txtCount= (TextView) 
view.findViewById(R.id.txtCount);         
txtCount.setText(count+"");
