i'm trying use newest design library make toolbar hide/show on scroll. issue scrolling content have in fragment, i'm injecting framelayout container , doesn't work. here's activity: 

<android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent">  <android.support.design.widget.coordinatorlayout     android:id="@+id/main_content"     android:layout_width="match_parent"     android:layout_height="match_parent">      <android.support.design.widget.appbarlayout         android:layout_width="match_parent"         android:layout_height="wrap_content">          <include layout="@layout/layout_toolbar" />      </android.support.design.widget.appbarlayout>      <framelayout         android:id="@+id/container"         android:layout_width="match_parent"         android:layout_height="match_parent"         app:layout_behavior="@string/appbar_scrolling_view_behavior" />  </android.support.design.widget.coordinatorlayout>  <framelayout     android:id="@+id/navigation_drawer_container"     android:layout_width="@dimen/navigation_drawer_width"     android:layout_height="match_parent"     android:layout_gravity="start"     tools:layout="@layout/fragment_nav_drawer_anon" />

and fragment:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical">  <android.support.v4.widget.swiperefreshlayout     android:id="@+id/pull_to_refresh"     android:layout_width="match_parent"     android:layout_height="match_parent">      <listview         android:id="@android:id/list"         android:layout_width="match_parent"         android:layout_height="match_parent"/> </android.support.v4.widget.swiperefreshlayout>  <textview     android:id="@android:id/empty"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:textsize="18sp"     android:fontfamily="sans-serif"     android:color="@color/dark_grey"     android:padding="60dp"/>

and toolbar:

<android.support.v7.widget.toolbar xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?attr/colorprimary" android:minheight="?attr/actionbarsize" app:layout_scrollflags="scroll|enteralways" style="@style/widget.myapp.actionbar" />

i'm following official doc , demo, , still can't figure out how make work.

replace framelayout android.support.v4.widget.nestedscrollview

nestedscrollview scrollview, supports acting both nested scrolling parent , child on both new , old versions of android. nested scrolling enabled default.
