How to hide a tab in Android tab layout?

Question

I have a tab layout containing 3 tabs. I want to add 4th tab at run time and hide this tab after some time. Please let me know how to hide a tab in Android.

Answer 1

Get TabHost from resource as

TabHost  tabHost = (TabHost)findViewById(android.R.id.tabhost);

Then runtime use this

tabHost.getTabWidget().getChildAt(3).setVisibility(View.GONE);

Supposing that you are trying to hide 4th Tab.(So 3 is used)

Answer 2

Well, I'm building an app that use a FragmentPagerAdapter as SectionsPagerAdapter in an activity. This activity was generated by AS and its layout has a TabLayout with some TabItems.

I wanted to hide one of them if var hide is false. Then I used:

Toolbar toolbar = findViewById(R.id.sectionBar);
if(!hide) {
    TabLayout.Tab tab = tabLayout.getTabAt(2);
    if(tab!=null) {
        tabLayout.removeTab(tab);
    }
}

I know that remove is not hide but it was my solution.
