RecyclerView does not enter under tabLayout and toolbar

I made the Toolbar and TabLayout transparent. In TabLayout, I have two fragments with RecyclerView.
When I scroll, the contents of the recyclerView do not go under the tolbar. Please tell me how to fix.
I use the behaviour but it seems not working

You should use this behavior in root of that view that want to place below of AppBarLayout, not in child of views (Fragments)
just add this behavior to ViewPager
just change :
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="112dp"
android:background="#color/transparent" />
to :
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="112dp"
android:background="#color/transparent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

How do I change the cardview position to the bottom of the tablayout?

I tried to create a cardview consisting of five items in a fragment. However, the cardview position is always at the top of the layout. I tried using margin and align, but it didn't work.
How do I change the position of the cardview?
Here is my card_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

This is my screenshot:

Give an id to your AppBarLayout (say, id=action_bar) and then simply add layout_below="#id/action_bar" to your ViewPager:
<android.support.v4.view.ViewPager
android:layout_below="#id/action_bar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/viewpager">
</android.support.v4.view.ViewPager>

Use Coordinator layout instead of Relative layout and set layout_behavior property into view pager to appbar_scrolling_view_behavior.

Move your include statement outside the appbarlayout and align it to parent's bottom like this:
<?xml version="1.0" encoding="utf-8"?>

When the appbar layout in fragment scrolls, the appbar layout of the activity also should scroll.
Currently when the touch is on the view pager in the fragment, both appbar scroll together, but when the touch is on the appbar of the fragment, only the appbar of fragment scrolls

CardView doesn't comes as Overlapping content

Followed this link Overlap scrolling view with AppBarLayout but overlapping doesn't seems to work well.Here i'm attaching my layout files with the output that i got.

Please have a look and give me your suggestion where i'm wrong.

By removing android:background="#android:color/white" from my custom layout and changing the CollapsingToolBar as app:layout_scrollFlags="scroll|enterAlwaysCollapsed",I resolved the issue.

Place Layout under the AppBar (like in Messenger)

Good afternoon,
I am trying to place a (Relative?Linear?Frame?)Layout under the AppBar and the above the ViewPager, like in the Facebook Messenger App.
Like "TOUS, MESSENGER, SMS" in the picture below :
Here is the code I tried, but it does not work, the Layout is not shown under the AppBar.
<?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.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways|snap" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
app:tabIndicatorColor="#color/fullWhite"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<!-- This is the part I need to put between the AppBar and the content (ViewPager), but it is not shown -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_frame">
<include layout="#layout/tous_messenger_sms"/>
</FrameLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:background="#color/separator_color"/>
</android.support.design.widget.CoordinatorLayout>
And here is my "tous_messenger_sms" layout file (the problem is probably not that) :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_marginLeft="16sp"
android:layout_marginRight="16sp">
<Button
style="?android:textAppearanceSmall"
android:layout_width="wrap_content"
android:layout_height="28sp"
android:id="#+id/tous_btn"
android:text="TOUS"
android:textColor="#color/colorPrimary"
android:layout_weight="1"
android:background="#drawable/button_shape_tous"
android:stateListAnimator="#null" />
<Button
style="?android:textAppearanceSmall"
android:layout_width="wrap_content"
android:layout_height="28sp"
android:id="#+id/messenger_btn"
android:text="MESSENGER"
android:textColor="#color/colorPrimary"
android:layout_weight="1"
android:background="#drawable/button_shape_messenger"
android:stateListAnimator="#null" />
<Button
style="?android:textAppearanceSmall"
android:layout_width="wrap_content"
android:layout_height="28sp"
android:id="#+id/sms_btn"
android:text="SMS"
android:textColor="#color/colorPrimary"
android:layout_weight="1"
android:background="#drawable/button_shape_sms"
android:stateListAnimator="#null" />
</LinearLayout>
