You can achieve it by having this layout:
<android.support.design.widget.CoordinatorLayout
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="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<!-- HEADER -->
<RelativeLayout
...
app:layout_collapseMode="parallax">
.....
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
<!-- IF YOU WANT TO KEEP "Choose Item" always on top of the RecyclerView, put this TextView here
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:text="choose item" />
-->
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
You pin your toolbar by having the app:layout_collapseMode="pin"
property set. You make RecyclerView
properly scrollable by setting app:layout_behavior="@string/appbar_scrolling_view_behavior"
and that's pretty much it.
NB! Position of "Choose item" TextView
depends on the particular behaviour you want to achieve:
- you can include it as a first element of your
RecyclerView
's Adapter
to scroll it away, once user start scrolling through the RecyclerView
;
- you can add it into
AppBarLayout
so it will always stick on top of the RecyclerView
, whenever you scroll it or not;
