mainactivity.java - setuptabicons()

private void setuptabicons() {     private int[] tabicons = {         r.drawable.ic_art_track_black_24dp,         r.drawable.ic_notifications_black_24dp,         r.drawable.ic_chat_bubble_black_24dp,         r.drawable.ic_person_add_black_24dp     };     (int = 0; < 4; i++) {         tablayout.gettabat(i).setcustomview(r.layout.custom_tab);         tablayout.gettabat(i).seticon(tabicons[i]);         tablayout.gettabat(i).settext("random");     } }

am doing wrong? alternative method appreciated. 

private void setuptabs() {     string[] titles = getresources().getstringarray(r.array.titles);     int[] icons = ----     (int = 0; < titles.length; i++) {         if (mtablayout != null) {             tablayout.tab tab = mtablayout.gettabat(i);             if (tab != null)                 tab.setcustomview(preparetabview(titles[i], icons[i]));         }     } }  private view preparetabview(string title, int icon) {     view view = view.inflate(getcontext(), r.layout.list_item_tab, null);     textview tabtitle = (textview) view.findviewbyid(r.id.tab_title);     imageview tabicon = (imageview ) view.findviewbyid(r.id.tab_icon);     tabtitle.settext(title);     tabicon.setimageresouce(icon);     return view; }
