CoordinatorLayout, AppBarLayout and ToolBar - Toolbar doesn't scroll off the screen
Solution 1
If you just want the toolbar to enter/exit AppBarLayout
is sufficient. You do not need a CollapsingToolbarLayout
. Try changing your FrameLayout
into a android.support.v4.widget.NestedScrollView
Solution 2
You should have something like this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="@dimen/detail_backdrop_height"
android:fitsSystemWindows="true"
android:theme="@style/AppTheme">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="@color/primary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="@+id/backdrop"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="@drawable/header"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="@+id/app_bar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<include layout="@layout/your_scrollable_view" />
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="@dimen/fab_margin"
android:clickable="true"
android:onClick="registrarNuevoUsuario"
android:src="@drawable/ic_action_check"
app:layout_anchor="@id/appbar"
app:layout_anchorGravity="bottom|right|end" />
</android.support.design.widget.CoordinatorLayout>
dimens.xml
<resources>
<dimen name="fab_margin">16dp</dimen>
<dimen name="detail_backdrop_height">256dp</dimen>
</resources>
Solution 3
Similar issue was reported on google https://code.google.com/p/android/issues/detail?id=201822
But after release of Android Support Library, revision 23.2.1 (March 2016) This bug is solved.
Fixed : AppBarLayout not scrolling out completely when used with fitsSystemWindow
update Support Library to Android Support Library to 23.2.1
OR to further.

I am trying to make my ToolBar scroll off the screen, when I scroll up my ViewPager(ViewPager is inside a fragment that is placed in FrameLayout) and show the ToolBar when I scroll down. I am trying to achieve this using the Support Design Library.
Here is my XML:
<?xml version="1.0" encoding="utf-8"?> <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" 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.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" app:layout_scrollFlags="scroll|enterAlways" android:background="?attr/colorPrimaryDark" android:elevation="4dp" app:popupTheme="@style/ThemeOverlay.AppCompat.Light" app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" > <TextView android:id="@+id/toolbar_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="" android:textColor="@android:color/white" android:textSize="20sp" /> <ProgressBar android:id="@+id/progressBar" android:layout_width="32dp" android:layout_height="32dp" android:layout_gravity="right" android:indeterminate="true" android:visibility="gone" /> </android.support.v7.widget.Toolbar> </android.support.design.widget.AppBarLayout> <FrameLayout android:id="@+id/detail_fragment_container" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.xx.xxx.DetailActivity" tools:ignore="MergeRootFrame" app:layout_behavior="@string/appbar_scrolling_view_behavior" > </FrameLayout> </android.support.design.widget.CoordinatorLayout>
But, the toolbar doesn't respond to scroll. What am I doing wrong?
