There is a ScrollView Activity with this code:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" xmlns:fab="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true"> <android.support.design.widget.AppBarLayout android:id="@+id/app_bar" android:layout_width="match_parent" android:layout_height="@dimen/app_bar_height" android:fitsSystemWindows="true" android:theme="@style/AppTheme.AppBarOverlay"> <android.support.design.widget.CollapsingToolbarLayout android:id="@+id/toolbar_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" app:contentScrim="?attr/colorPrimary" app:layout_scrollFlags="scroll|exitUntilCollapsed" android:background="IMG" android:clickable="true" android:onClick="CLK" android:duplicateParentState="false" app:titleEnabled="false"> </android.support.design.widget.CollapsingToolbarLayout> </android.support.design.widget.AppBarLayout>

When you change the rotation of the screen, the picture is stretched, and it turns out not very nice, can you somehow cancel the stretching of the picture?

    No need to put a background image in CollapsingToolbarLayout . Create an ImageView with a picture and place it inside the CollapsingToolbarLayout .
