@ Overridepublic boolean onCreateOptionsMenu (Menu menu) {// Inflate the menu; this adds items to the action bar if it is present. getMenuInflater (). inflate (R. menu. main, menu); // you can add some logic (hide it if the count = 0) if (badgeCount> 0) {ActionItemBadge. update (this, menu. findItem (R. id. item_samplebadge), Iconify. iconValue. fa_android, ActionItemBadge. badgeStyle. DARKGREY, badgeCount);} else {ActionItemBadge. hide (menu. findItem (R. id. item_samplebadge);} // If you want to add your ActionItem programmatically you can do this too. you do the following: new ActionItemBadge. add (). act (this ). menu (menu ). title (R. string. sample_2 ). itemDetails (0, SAMPLE2_ID, 1 ). showAsAction (MenuItem.
