android - Tab navigation in new HoloEverywhere not displays fragment after screen rotation -

yesterday downloaded new holoeverywhere library. currently, have problem tab navigation after screen rotation.

my home activity:

public class mainactivity extends activity implements tablistener {     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setuptabs();     }  private void setuptabs() {     string[] titles = {             "first", "second",     };      actionbar supportactionbar = getsupportactionbar();      (int = 0; < titles.length; i++) {         actionbar.tab tab = supportactionbar.newtab();          tab.settext(titles[i]);         tab.settag(myfragment.tag);          tab.settablistener(this);         supportactionbar.addtab(tab, false);      }      supportactionbar.setnavigationmode(actionbar.navigation_mode_tabs);      supportactionbar.setselectednavigationitem(0);  }  @override public void ontabselected(tab tab, fragmenttransaction fragmenttransaction) {     final string fragmenttag = tab.gettag().tostring();     fragment fragment = getsupportfragmentmanager().findfragmentbytag(fragmenttag);     if (fragment == null) {         fragment = new myfragment();         fragmenttransaction.add(android.r.id.content, fragment, fragmenttag);     } else {         fragmenttransaction.attach(fragment);     } }  @override public void ontabunselected(tab tab, fragmenttransaction fragmenttransaction) {      fragment fragment = getsupportfragmentmanager().findfragmentbytag((string)     tab.gettag());      if (fragment != null) {         fragmenttransaction.detach(fragment);     } }  @override public void ontabreselected(tab tab, fragmenttransaction fragmenttransaction) { } }  

and fragment class.

public class myfragment extends fragment { public static final string tag = myfragment.class.getcanonicalname();  @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view view = new view(getactivity());     view.setbackgroundcolor(color.black);     return view; } } 

when rotate screen fragment not displaying. displays when select tab (which not selected) manually.

i solve problem. post code here , see if can :d

if (savedinstancestate == null){     tabhomefragment homefragment = new tabhomefragment();     fragmenttransaction transaction = getsupportfragmentmanager().begintransaction();     transaction.replace(r.id.container, homefragment, "home_fragment").commit(); }else{     tabhomefragment homefragment = (tabhomefragment) getsupportfragmentmanager().findfragmentbytag("home_fragment"); } 

those code located in oncreate method. when device rotate , ortiention change, fragment recreate again. add if clase check if there 1 here.

but using normal fragment in android. hope can little.
