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" />

Android how to make recyclerview overscroll bounce affect when pulled past limits?

I am searching for a way to make my recycleView elastic at the top when pulled. Let me show you a image of what i want:
https://raw.githubusercontent.com/baoyongzhang/android-PullRefreshLayout/master/demo.gif
So you can see from that gif, that when the user pulls down on the very top of the list it kind of has an elastic bounce affect. How do i achieve that ? i want this affect so my swipeRefreshLayout doesn't get triggered so easily just by reaching the top. i want them to actually PULL to refresh not just reach the top. my appbar layout looks like this right now:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

/>
</LinearLayout>
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
and inside of a tab i have the following recyclerView:
<?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="match_parent"

android:id="#+id/recyclerView"
android:layout_marginTop="0dp"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>
in my activity i tried calling this but it does not work:
mRecyclerView.setOverScrollMode(View.OVER_SCROLL_ALWAYS);

Hiding tablayout inside coordinator layout, which is outside activity

I have some problem with coordinator layout. I have activity toolbar inside appBarLayout with parent CoordinatorLayout (I want to make toolbar hideable) and fragment with tablayout inside appBarLayout and viewPager. Here is activity's 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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/gradient"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/toolbar_container"
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="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways|snap"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.design.widget.CoordinatorLayout>
And it's fragment's 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"

android:layout_height="match_parent"
android:background="#drawable/gradient"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
style="#style/MyCustomTabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"/>
</android.support.design.widget.AppBarLayout>
<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.support.design.widget.CoordinatorLayout>
For now, I have this situation where the toolbar is somewhere.
If I change coordinator layout inside activity to linear layout I get toolbar visible, but as you can imagine with no hiding option.
Actually, I have play with coordinator layout a lot:hiding and showing toolbar in a few cases such parallax and others - https://github.com/Iamtodor/toolbars, so you can be sure, I have a little understand how it works :)
Also, I had wantch this sources:
- https://github.com/codepath/android_guides/wiki/Handling-Scrolls-with-CoordinatorLayout
- https://github.com/codepath/android_guides/wiki/Using-the-App-ToolBar#using-toolbar-as-actionbar
- https://github.com/chrisbanes/cheesesquare
But there is all examples when tablayout exists inside same appbarlayout with toolbar.
How can I fix it?

Here is what worked for me:

fragment from viewPager hidding behind on tab of action bar

Actually i am trying to build a listView/recyclerView . On scrolling of list the actionbar get hide where action bar is toolbar but the some part of listview is hiding behind the tab. Here i have used AppBarLayout and toolbar having app:layout_scrollFlags="scroll|enterAlways" and in my recylerview have app:layout_behavior="#string/appbar_scrolling_view_behavior" behaviour. I can use linear Layout but problem is for sliding of toolbar the AppBarLayout must be the child of CoordinatorLayout.
My activity having xml
<?xml version="1.0" encoding="utf-8"?>

and my fragment having

android:layout_height="match_parent"
android:scrollbars="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
</android.support.design.widget.CoordinatorLayout>
Am I doing something wrong in making the toolbar to slide on sliding the listview or there is another way of doing this without using any third library.

try this:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:popupTheme="#style/Theme.AppCompat.Light.DarkActionBar"
app:theme="#style/Toolbar">
<android.support.v7.widget.Toolbar
android:id="#+id/action_bars"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
/>
<ameyo.genie.SlidingTabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="#color/colorPrimary"
/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="50dp">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</android.support.design.widget.AppBarLayout>
When you put your component, order them by the position, every component will be over the precedent, if there's no space !

Thanks to Daniel Nugent that I forgot to write android:layout_below="#+id/sliding_tabs" inside viewpager and also remove framelayout and height must be wrapcontent now my final code is this which is working

AppBarLayout Scroll Behavior

I am using the design support library to build a material viewpager. The code for the xml file is as follows:
<?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/coordinatorLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
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:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabLayout"
style="#style/TabLayoutStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<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.support.design.widget.CoordinatorLayout>
One of the fragments on the viewpager has a recycler view inside a relative layout. The code is:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/layout"
android:layout_width="match_parent"
android:padding="2.5dip"
android:layout_height="match_parent"
android:orientation="vertical">
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="50dip"
android:layout_height="50dip"
android:layout_centerInParent="true"
android:layout_margin="20dip"
android:indeterminate="false" />
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="none"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:visibility="gone" />
</RelativeLayout>
The result i want is when the recyclerview scrolls, the toolbar should scroll away from view leaving the tablayout only, but what i have is on scroll, the tablayout scrolls out of view leaving the toolbar.
How can i achieve this?
