TabLayout tab selection

If you know the index of the tab you want to select, you can do it like so:

TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
TabLayout.Tab tab = tabLayout.getTabAt(someIndex);
tab.select();

This technique works even if you’re using the TabLayout by itself without a ViewPager (which is atypical, and probably bad practice, but I’ve seen it done).
