How to destroy an unselect tab? or replace the current tab with a new one? TABLAYOUT android -


i´m trying delete/remake/replace or destroy tabs aren´t selected. can reload/create tab , content refreshed. since onresume doesn´t work on tablayout.

i´m using tablayout here mainactivity code:

public class mainactivity extends appcompatactivity{     // declaring view , variables     toolbar toolbar;     viewpager viewpager;     viewpageradapter adapter;     tablayout tablayout;     charsequence titles[]={"participantes","torneio","classificação"};     int numboftabs =3;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         toolbar = (toolbar) findviewbyid(r.id.tool_bar);         viewpager = (viewpager) findviewbyid(r.id.viewpager);         tablayout = (tablayout)findviewbyid(r.id.tablayout);           // creating toolbar , setting toolbar activity         setsupportactionbar(toolbar);         // creating viewpageradapter , passing fragment manager, titles fot tabs , number of tabs.         adapter =  new viewpageradapter(getsupportfragmentmanager(),titles,numboftabs);         // assigning viewpager view , setting adapter         viewpager.setadapter(adapter);           tablayout.setupwithviewpager(viewpager);         tablayout.setselectedtabindicatorcolor(getresources().getcolor(r.color.colortexticons));         tablayout.setontabselectedlistener(new tablayout.ontabselectedlistener() {             @override             public void ontabselected(tablayout.tab tab) {                viewpager.setcurrentitem(tab.getposition());             }              @override             public void ontabunselected(tablayout.tab tab) {              }              @override             public void ontabreselected(tablayout.tab tab) {              }         });     }      @override     protected void ondestroy() {         super.ondestroy();         viewpager = null;     }      @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.menu, menu);         return true;     }      @override     public boolean onoptionsitemselected(menuitem item) {         // handle action bar item clicks here. action bar         // automatically handle clicks on home/up button, long         // specify parent activity in androidmanifest.xml.         int id = item.getitemid();          //noinspection simplifiableifstatement         if (id == r.id.action_settings) {             return true;         }         if (id == r.id.action_info) {             toast.maketext(getapplicationcontext(), "contacto: juniortalisson16@gmail.com", toast.length_long).show();             return true;         }         return super.onoptionsitemselected(item);     }   } 

my adapter code:

   /**      * created talisson on 03-04-2016.      */  public class viewpageradapter extends fragmentstatepageradapter {      charsequence titles[]; // store titles of tabs going passed when viewpageradapter created     int numboftabs; // store number of tabs, passed when viewpageradapter created       // build constructor , assign passed values appropriate values in class     public viewpageradapter(fragmentmanager fm,charsequence mtitles[], int mnumboftabsumb) {         super(fm);          this.titles = mtitles;         this.numboftabs = mnumboftabsumb;      }      @override     public void destroyitem(viewgroup container, int position, object object) {         super.destroyitem(container, position, object);         fragmentmanager manager = ((fragment) object).getfragmentmanager();         fragmenttransaction trans = manager.begintransaction();         trans.remove((fragment) object);         trans.commit();     }        //this method return fragment every position in view pager     @override     public fragment getitem(int position) {          switch(position) {// if position 0 returning first tab             case 0:             tab1 tab1 = new tab1();             return tab1;             case 1:             tab2 tab2 = new tab2();             return tab2;             case 2:             tab3 tab3 = new tab3();             return tab3;             default:                 return null;         }       }      // method return titles tabs in tab strip      @override     public charsequence getpagetitle(int position) {         return titles[position];     }      // method return number of tabs tabs strip      @override     public int getcount() {         return numboftabs;     } }
