java - Android toolbar inside a tab menu retrieval -


how menu toolbar inside fragment (tab)? i'm relatively new android , java.

here's code:

import android.os.bundle; import android.support.annotation.nullable; import android.support.v4.app.fragment; import android.support.v7.app.actionbaractivity; import android.support.v7.widget.toolbar; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup;  public class tab1 extends fragment {  @override public view oncreateview(layoutinflater inflater, @nullable viewgroup container, @nullable bundle savedinstancestate) {     view view =inflater.inflate(r.layout.tab_1,container,false);      toolbar toolbar = (toolbar) view.findviewbyid(r.id.tool_bar);     actionbaractivity activity = (actionbaractivity) getactivity();     activity.setsupportactionbar(toolbar);      return view; } }

move toolbar activity , use oncreateoptionsmenu() in fragment inflate menu need , add sethaoptionsmenu(true) in oncreate() of fragment.
