I want to overlap a AppBarLayout which contains a toolbar with a persistent bottomsheet(when it is in expanded state only).Please tell me at least a hint if it is possible.
This is my layout file where my AppBarLayout is defined
<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"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<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_height="wrap_content"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:minHeight="?attr/actionBarSize"
app:title="Home"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:background="?attr/colorPrimaryDark">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
</android.support.design.widget.CoordinatorLayout>
The included layout content_main is where my bottomsheet lives.
I got it.The bottomSheet will overlap the toolbar if there is no
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
The appbarlayout makes itself compulsary to be shown throughout the navigationdrawer (if the navigations are fragments).

I am experiencing a weird toolbar scrolling issue. After I scroll the toolbar up and while it's moving upward with inertia (fling), I try to stop the child view by touching on the NestedScrollView and the toolbar is automatically expanded. (both views jump back as you can see toward the end of the attached gif.)
My layout is pretty straightforward. It's based on Android Studio project template.
Any thought of how to make the behavior looks more natural?

</android.support.design.widget.CoordinatorLayout>
you need to add a CollapsingToolbarLayout widget inside AppBarLayout. so when you scroll down/up the Toolbar/Appbar will collapse/expand smoothly.
The whole appbarlayout should be changed to:
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:theme="#style/ThemeOverlay.AppCompat.Dark"
app:expandedTitleTextAppearance="#style/CollapsingToolbarTitleText"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="#dimen/article_keylines"
app:expandedTitleMarginStart="#dimen/md_keylines"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
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>
I want to hide the ActionBar on ListView scroll.
The official documentation suggests we use this pattern to do so:
<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">
<! -- Your Scrollable View -->
<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.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
...
app:layout_scrollFlags="scroll|enterAlways">
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
I can't, however, use this pattern since my "Scrollable view" is a ListView inside a Fragment that is rendered inside the ViewPager. I use the following code in my app:
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.x.y.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="#dimen/appbar_padding_top"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
style="#style/AppTabLayout"
android:id="#+id/tabs"
app:tabTextAppearance="#style/AppTabTextAppearance"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
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.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:src="#mipmap/ic_add_white_24dp" />
</android.support.design.widget.CoordinatorLayout>
I've tried putting the ViewPager inside the AppBarLayout, and the Toolbar and TabLayout in a CollapsibleToolbarLayout. However, if I do that, the ViewPager layout isn't even shown and the ActionBar is permanently hidden.
What do I do?
CoordinatorLayout doesn't work with listview. So either replace the listview with a recyclerview (which i would highly recommend) or put your listview inside a NestedScrollView. The xml code you posted is ok. If any of these is not working then post your fragment's xml code and hit me up again
I'm trying to create an activity with an CoordinatorLayout, Viewpager and in there a normal view with a FAB. The layout I'm trying to create is:
- CoordinatorLayout
- ViewPager
- View with FAB
- View
- etc
So in my case I need to include the FAB in the view inside the ViewPager.
My problem is right now (in a simplified application):
https://gfycat.com/VacantAdmiredBedlingtonterrier
The problem in the GIF is that the FAB moves out of the screen. It moves exactly the height of the toolbar.
What I want is that the FAB would stay put at its position but inside the viewpager and in the view.
The XML of this view is:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="?attr/actionBarSize"

</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal"/>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/text_margin"
android:text="#string/large_text" />
</android.support.v4.widget.NestedScrollView>
</FrameLayout>
As shown in the XML is that the FAB is not in the scrollview but is inside the FrameLayout, which would represent a ViewPager.
Is there any way to make this FAB stay put at it's position but keeping the view inside a viewpager?
I'm working on creating a layout that works as follows:
Toolbar at the top
Toolbar below top toolbar
RecyclerView
And when I scroll, I want to hide the toolbar in between top toolbar and recyclerView. My Layout is as follows:
<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:fitsSystemWindows="true"
tools:context="SomeActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="4dp"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:layout_scrollFlags="scroll|enterAlways"/>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="50dp"
android:minHeight="0dp"
android:id="#+id/info_bar"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/content_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
With these changes, both the toolbars become hidden when scrolling.
I just need to hide the second toolbar.
EDIT : If I can't get this to work, I'll be attaching a scroll listener to my recyclerView and resolving this that way. But I was wondering if there is a cleaner solution with scroll behaviors
Moved the top toolbar out of the coordinatorlayout and thus resolved this issue.
(Thanks to a colleague)

If I understood properly, then you might want to collapse hole collapseableToolbar when it is scrolled up, instead it is showing some (20dp) space between ToolBar and listItem. for me it took half of the day, and problem is just a boolean value in coordinatorLayout. Just change "fitsSystemWindows" value from true to false.
with this you can hide image of the collapseToolBar upon scrolling.
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

I have set up a DrawerLayout and a CoordinatorLayout in order to use a modern layout with a NavigationView and collapsing toolbar.
It works just fine until the device is rotated. Then the main_content is moved to a new permanent location. If I remove the appbar_scrolling_view_behavior from the main_content FrameLayout rotation works, but the content is no longer aware of the Toolbar.
Any advice?

A few points that should collectively resolve your problem:
The height of the AppBarLayout determins the expanded size of the collapsing toolbar, whilst the Toolbar determins the collapsed size. As such, you should set the AppBarLayout height to something more than the Toolbar (i.e. 280dp) to see the collapsing behaviour.
Immediately inside the AppBarLayout should be a CollapsingToolbarLayout, which contains the Toolbar and, optionally, other views too (normally an ImageView with a parallax collapse mode)
For the toolbar to collapse and expand correctly, it relies on a ViewGroup that supports nested scrolling (RecyclerView or NestedScrollView. As such, in your example you should try either changing main_content from a FrameLayout to a NestedScrollView, or conversely change the FrameLayout that forms the root layout of Fragment into a NestedScrollView.
Here is an example:
