android - TabLayout scroll without a recyclerView -

i using new material design libraries:

 compile 'com.android.support:design:22.2.0'  compile 'com.android.support:appcompat-v7:22.2.0'  compile 'com.android.support:recyclerview-v7:22.2.0' 

and have typical simple layout (3 tabs) in cheesquareapp

here each tab fragment simple recyclerview

layout - fragment_cheese_list.xml

<android.support.v7.widget.recyclerview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/recyclerview"     android:layout_width="match_parent"     android:layout_height="match_parent" /> 

and works great. change layout fragment_cheese_list.xml have other items. such example.

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:gravity="center"     android:orientation="vertical">      <progressbar         android:id="@+id/progress"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:indeterminate="true"         android:visibility="gone"/>      <linearlayout         android:id="@+id/empty_list_layout"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:orientation="vertical"         >          <textview             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="no results, tap button search again"/>          <button             android:id="@+id/btn_search"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="search"/>      </linearlayout>      <android.support.v7.widget.recyclerview xmlns:android="http://schemas.android.com/apk/res/android"         android:id="@+id/recyclerview"         android:layout_width="match_parent"         android:layout_height="match_parent"      android:visibility="gone"/>  </linearlayout> 

as can see here, show recyclerview when there items, , if there no items, hide show button , text. switching visibilities (view.gone - view.visible).

i have of done already, problem when recyclerview not visible, cannot "scroll" layout hide/show toolbar last image in picture

so brings lot of problems, if switch 1 tab one, while having toolbar hidden, cannot show toolbar again, unless switch tabs , scroll show it.

thanks

edit: maybe there way programatically code when viewpager changes, hide/show animation toolbar. although not best solution workaround, if knows please post how code (tried code did not work)

you need wrap button & label nestedscrollview.

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:orientation="vertical" >  <progressbar     android:id="@+id/progress"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:indeterminate="true"     android:visibility="gone"     />  <android.support.v4.widget.nestedscrollview     android:id="@+id/nested_scroll_view"     app:layout_behavior="@string/appbar_scrolling_view_behavior"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:fillviewport="true"     >      <linearlayout         android:id="@+id/empty_list_layout"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:orientation="vertical"         >          <textview             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="no results, tap button search again"             />          <button             android:id="@+id/btn_search"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="search"             />      </linearlayout>  </android.support.v4.widget.nestedscrollview>  <android.support.v7.widget.recyclerview     android:id="@+id/recyclerview"     android:layout_width="match_parent"     android:layout_height="match_parent"      android:visibility="gone"     />  </linearlayout>
