java - android toolbar inside a tab -

i want make toolbar inside 1 of tabs nothing works me. can done? have toolbar above tabs need appear inside first tab.

here's code (with toolbar above tabs):

import ...  public class mainactivity extends actionbaractivity {  toolbar toolbar; viewpager pager; viewpageradapter adapter; slidingtablayout tabs; charsequence titles[] = {"projects", "people", "files"}; int numboftabs = 3;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      toolbar = (toolbar) findviewbyid(r.id.tool_bar);     setsupportactionbar(toolbar);      adapter = new viewpageradapter(getsupportfragmentmanager(), titles, numboftabs);     pager = (viewpager) findviewbyid(r.id.pager);     pager.setadapter(adapter);     tabs = (slidingtablayout) findviewbyid(r.id.tabs);     tabs.setdistributeevenly(true);      tabs.setviewpager(pager); }   @override public boolean oncreateoptionsmenu(menu menu) {     getmenuinflater().inflate(r.menu.menu_primary, menu);     return true; }  final arraylist<string> listitems = new arraylist<string>();  @override public boolean onoptionsitemselected(menuitem item) {     int id = item.getitemid();      if (id == r.id.addbutton) {         final textview noproject = (textview) findviewbyid(r.id.noproject);         final listadapter addadapter = new arrayadapter<string>(this,                 r.layout.list_item, r.id.listframe, listitems);         final listview lv = (listview) findviewbyid(r.id.lv);         lv.setadapter(addadapter);          noproject.setvisibility(view.gone);         lv.setvisibility(view.visible);         listitems.add("new project");          lv.setonitemclicklistener(new adapterview.onitemclicklistener() {             @override             public void onitemclick(adapterview<?> parent, view view, int position, long id) {                 intent switchtoedit = new intent(mainactivity.this,                         teamcreate.class);                 startactivity(switchtoedit);             }         });     }     return super.onoptionsitemselected(item); } } 

first tab:

import ...  public class tab1 extends fragment {  @override public view oncreateview(layoutinflater inflater, @nullable viewgroup container, @nullable bundle savedinstancestate) {     view v =inflater.inflate(r.layout.tab_1,container,false);     return v; } } 

i faced similar challenge non-standard toolbar , tabs , got past it, though frankly results odd looking. can toolbar work under tab using similar technique, may leave users scratching heads. technique have 2 toolbars, 1 holding tablayout widget , 1 inside fragment(s) in viewpager.

i using material design tabs detail view in app. looked fine until did 2-pane master-detail view tablets. had issue tabs wanting directly under toolbar, no obvious way have master & detail share toolbar tabs showing under detail portion of screen.

i got working by:

1. create "noactionbar" style in styles.xml, refer in main layout using "android:theme="@style/apptheme".

   <!-- turn off normal application bar can put our toolbars please.  replacing "theme.appcompat.light.darkactionbar" noactionbar  per http://www.truiton.com/2015/04/android-action-bar-dialog-using-toolbar/ --> <style name="apptheme" parent="materialtheme.base"/> <style name="materialtheme.base" parent="theme.appcompat.light.noactionbar"> <item name="windownotitle">true</item> <!--we using toolbar no need show actionbar--> <item name="windowactionbar">false</item> 

2. toss android.support.design.widget.coordinatorlayout , use linearlayout.

3. here snippet has toolbar containing tabs taking part of screen real estate rather entire width. note toolbar has "app:layout_scrollflags="scroll|enteralways":

     <framelayout android:id="@+id/detail_container"          android:layout_width="0dp"          android:layout_height="match_parent"          android:layout_gravity="end"          android:layout_weight="2"          tools:name="com.android.bazemom.popularmovies.tabcontainerfragment" > <!-- second toolbar used tabs --> <android.support.v7.widget.toolbar     android:id="@+id/toolbar"     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:background="?attr/colorprimary"     android:minheight="?attr/actionbarsize"     app:layout_scrollflags="scroll|enteralways"     />  <android.support.design.widget.tablayout     android:id="@+id/tabanim_tabs"     android:layout_width="match_parent"     android:layout_height="wrap_content"     />  <!-- helps handing fragments load each tab --> <android.support.v4.view.viewpager     android:id="@+id/tabanim_viewpager"     android:layout_width="match_parent"     android:layout_height="match_parent"     app:layout_behavior="@string/appbar_scrolling_view_behavior"/> 

here master-detail view looked on wide tablet. tabs circled in green. toolbar action above tabs.
