FloatingActionButton is not displaying in CollapsingToolbarLayout

Hi I need to display 2 EditText and FloatingActionButton in CollapsingToolbarLayout. I have used this Code to display CollapsingToolbarLayout but my FloatingActionButton is not visible in Real Device(Redmi Note 4).
XML CODE
<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="wrap_content"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:statusBarScrim="?attr/colorAccent">

android:layout_margin="#dimen/fab_margin"
app:layout_anchor="#id/appbar"
app:layout_anchorGravity="bottom|end"
app:srcCompat="#drawable/ic_add_black_24dp" />

The code you pasted is not the full code neither has NavigationView since the picture you provided shows that there is a NavigationView (with at least a DrawerLayout) which contains CoordinatorLayout and etc.
However, this code works:
<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:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_tool_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:statusBarScrim="?attr/colorAccent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="72dp"
android:layout_marginTop="136dp"
android:layout_marginEnd="16dp"
android:layout_marginBottom="32dp"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/floating_action_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="16dp"
app:fabSize="normal"
app:layout_anchor="#+id/appbar"
app:layout_anchorGravity="bottom|end"
app:srcCompat="#drawable/ic_settings_white_24dp" />
</android.support.design.widget.CoordinatorLayout>
Result:
Perhaps you need "+" in app:layout_anchor="#+id/appbar" or, there is another problem with the DrawerLayout if this code didn't help. Also, make sure CoordinatorLayout is the child of DrawerLayout at the end.

Android - Remove shadow between Toolbar and TabLayout

I'm trying to make a layout with CollapsingToolbarLayout. But I do not get one thing. I want to remove the shadow between Toolbar and TabLayout. I've tried several ways and I have not managed to remove the shadow. Can anybody help me? Thank you

Try setting app:elevation="0dp" (not android:elevation) for your AppBarLayout.
In case you don't have the app namespace in your xml, add xmlns:app="http://schemas.android.com/apk/res-auto".
The difference between these two properties can be found here.
After that, check that you're not adding some background/border with any of these properties:
<android.support.design.widget.TabLayout
android:background="?attr/colorPrimary"
android:translationZ="2dp"
app:layout_anchor="#+id/appbar"
app:layout_anchorGravity="bottom"
app:tabGravity="fill"
app:tabIndicatorColor="#android:color/white"/>
Or the theme you're using for the AppBarLayout.

<android.support.design.widget.AppBarLayout
android:id="#+id/appBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
app:titleTextColor="#android:color/white" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_tablayout" />
Use app:elevation="0dp" to remove the shadow. It has always worked for me. Hope it works for you.
And also by programatically,
appBar.setOutlineProvider(null);

You have to put the Toolbar and the TabLayout in the same AppBarLayout
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="200dp"

Take a look at this issue

I know the question is already answered. But I want to share something that I learnt the hard way so that people who are facing the same problems can save time.
You need to wrap AppBarLayout inside CoordinatorLayout or else app:elevation will not work.
Working example:
<CoordinatorLayout>
<AppBarLayout>
<Toolbar>

CollapsingToolbarLayout in combination with SwipeRefreshLayout and Recyclerview not working

I am struggling to get my toolbar to collapse, I have seen some other topics on stackoverflow that -seem- to be related, but modification to my code didn't help the situation.
The swiperefreshlayout still does it's job, and I can still scroll through the recyclerview-items, but my bar isn't collapsing..
Additionally : it seems that the toolbar is overlapping a part of my recyclerview now
Code:
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:elevation="6dp"
android:onClick="showInputDialog"
android:src="#drawable/ic_action_add"
app:layout_anchor="#id/appbar"
app:layout_anchorGravity="bottom|right|end"
/>
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/MyToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swiperefresh"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:layout_collapseMode="parallax">
<android.support.v7.widget.RecyclerView
android:id="#+id/aandelenlijst"

android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>

Android collapsing layout once collapsed, doesn't show up again

I wrote an XML for AppBarLayout with collapsible ImageView. And, I want only the image view being collapsed Whereas, the toolbar should get pinned when I scroll up. I'm able to produce a similar thing, but once the ImageViewis collapsed, it doesn't show up again on scrolling down.
I suspect that the problem is with layout_scrollFlags but I tried every flag. On applying other flags, the toolbar doesn't get pinned. Can anyone point me where i have done the mistake?
here's my XML:
`
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:layout_width="match_parent"
android:layout_height="192dp"
android:scaleType="centerCrop"
android:src="#drawable/rsz_bg_cover"
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:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorAccent"
app:tabIndicatorColor="#color/colorPrimary"
app:tabMode="scrollable"
app:tabSelectedTextColor="#android:color/white"
app:tabTextColor="#EEE"
app:layout_collapseMode="pin"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"

Thanks koraokyo,
Your suggestions did make the hings clear for me. However, the solution you provided were not solving the problem. Hence I played around and things seem to work as I wanted. I moved the TabLayout inside AppBarLayout under another CollapsingToobarLayout and everything is perfect now. here's my AppBarLayout now.
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="192dp"
android:scaleType="centerCrop"
android:src="#drawable/rsz_bg_cover"
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:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#color/colorAccent"
app:layout_collapseMode="pin"
app:tabIndicatorColor="#color/colorPrimary"
app:tabMode="scrollable"
app:tabSelectedTextColor="#android:color/white"
app:tabTextColor="#EEE" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

The CollapsingToolbarLayout is designed to be the sole child of a AppBarLayout. Instead of having the TabLayout as a child of the AppBarLayout, move it outside (so it is a child of the CoordinatorLayout) and anchor it to the app bar.
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#color/colorAccent"
app:tabIndicatorColor="#color/colorPrimary"
app:tabMode="scrollable"
app:tabSelectedTextColor="#android:color/white"
app:tabTextColor="#EEE"
app:layout_anchor="#+id/app_bar_layout"
app:layout_anchorGravity="bottom"/>

I think that's the problem ViewPager. Try use android.support.v7.widget.RecyclerView or NestedScrollView instead ViewPager.

Android AppBarLayout pushes ViewPager down

I have below xml file which has 1)Toolbar 2)TabLayout 3)Custom View and 4) ViewPager. When i put Toolbar, TabLayout, Custom View inside AppBarLayout, it pushes ViewPager down as like this:

When i scroll down, Toolbar gets hidden which is good. But My ViewPager overflows main screen and bottom of ViewPager is not visible. What can i try?
When i scroll up Toolbar gets invisible and ViewPager is pulled up and fully visible in screen. But Toolbar only responds to scroll of 1st page of ViewPager. trick: For now i put paddingBottom to frament inside ViewPager

This is not an actual solution but for time being I added this line of code in view pager and its working:
android:paddingBottom="?attr/actionBarSize"
so my full layout is:
