Change application title when switching tabs

Question

There is no problem with the programmatic change of the application header (I will do this via getActionBar().setTitle() ); What is the shortest way to implement getting the current tab? I know there is an onTabSelected method, but I did not find normal (= concise) examples. Ideally, I see a switch-case block surrounded by a similar onTabSelected method:

 ... tabSpec = tabHost.newTabSpec("tab1"); ... switch (tag) { case "tab1": getActionBar().setTitle("Вкладка1"); case "tab2": getActionBar().setTitle("Вкладка2"); case "tab3": getActionBar().setTitle("Вкладка3"); case "tab4": getActionBar().setTitle("Вкладка4"); default: break; }

I created tabs via TabHost (there are other ways, as it turned out).

Look toward TabLayout. TabHost is an ancient version. tabLayout works with the viewpager. TabLayout has addOnTabSelectedListener. There put TabLayout. OnTabSelectedListener and redefine ontabSelected

 tabs.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { @Override public void onTabSelected(TabLayout.Tab tab) { switch (tab.getPosition()) { case 0: getActionBar().setTitle("Вкладка1"); break; case 1: getActionBar().setTitle("Вкладка2"); break; default: break; } } @Override public void onTabUnselected(TabLayout.Tab tab) { } @Override public void onTabReselected(TabLayout.Tab tab) { } });

I have been looking for a solution for a very long time how to make an icon in the tab without a title;
in TabLayout it possible to easily remove the title and leave only the icon?
