}

try adding super constructor:

public void ondrawerclosed(view view) {     super.ondrawerclosed(view);     getsupportactionbar().settitle(mtitle);     invalidateoptionsmenu();      if (fragment != null) {         _setfragmentcontainer(fragment, listsidemenuitems.get(position).title);     } }  public void ondraweropened(view drawerview) {     super.ondraweropened(drawerview);     getsupportactionbar().settitle(mdrawertitle);     // calling onprepareoptionsmenu() hide action bar icons     invalidateoptionsmenu(); }
