TabLayout at bottom of screen

How to place the TabLayout at bottom of screen in Android?
Following is my layout file where TabLayout is just below toolbar:
<?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:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="in.brewtv.activities.HomeActivity">
<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="30dp"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"
android:fillViewport="false" />
</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.CoordinatorLayout>
Could have been easy with RelativeLayout, but android:layout_alignParentBottom="true does not seem to work with CoordinatorLayout.

</RelativeLayout>
I just want to make my Toolbar static how can I achieve Thanks in advance!!

Remove app:layout_scrollFlags="scroll|enterAlways" this from Toolbar and check scroll.

Okay there are lot of answers but ,
Is this what are you looking for?
If yes, you can use CollapsingToolbarLayout
For the second view here is my xml all you need to remove ImageView to get the first view.
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="wrap_content"
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"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/profile_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/monkey"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
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.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffe5e5e5"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/activity_second" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
Take a note that I've used app:layout_collapseMode="pin" for Toolbar
Have fun ^_^

Make your layout like this. Your toolbar will be fixed at top while you scroll your layout.
<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:fitsSystemWindows="true"
>
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed|enterAlwaysCollapsed"
app:statusBarScrim="#color/primary"
app:contentScrim="#color/primary"
app:titleEnabled="false"
app:layout_collapseMode="none"
android:fitsSystemWindows="true">
<!--
we must create the value entry for the toolbar height here as different version would have different heights
-->
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:gravity="top"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"

I don't understand why recyclerview in nestedscrollview load all data

I am worried about RecyclerView in NestedScrollView loading all data.
I just want RecyclerView to load a part of data as many as visible on screen, not all data.
The main view of my app consists of CollapsingToolbarLayout a TabLayout, and a ViewPager.
One fragment of ViewPager has a NestedScrollview for collapsing up CollapsingToolbarLayout.
Also, that fragment (of FrameLayout of second xml) has the real RecyclerView.
I don't understand why the RecyclerView in NestedScrollView is loading all the data. Once I remove the NestedScrollView, all works good.
But I think I might use NestedScrollView for collapsing up CollapsingToolbarLayout. How can I resolve it? Thank you in advance

Why my Tab Layout and Toolbar are showing like this?

As you can see in the image. These two are not aligned properly. I am not able to understand why this is happening.
My toolbar is in Coordinator Layout in app_bar_main.xml and my Tab Layout is in fragment_main. I didn't add the tab layout in coordinator layout because I don't want to show it in all my views, just in my fragment main file.
My code in app_bar_main.xml:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:fitsSystemWindows="true">
<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
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"

app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
Code in fragment_main.xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="40dp"

android:backgroundTint="#FFFFFF"
app:tabMode="fixed"
app:tabGravity="fill"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/view_pager_1">
</android.support.v4.view.ViewPager>
</FrameLayout>
Can you tell what I am doing wrong?

For those who were not able to solve this.
I was able to solve it through an approach.
I added the above code in Main Activity and then set the visibility of tablayout and Toolbar in other fragments as GONE and in fragment which I want it to enable as VISIBLE.
To set visibility as gone you do:
TabLayout tabLayout = (TabLayout) getActivity().findViewById(R.id.tabs);
tabLayout.setVisibility(View.GONE);
ViewPager viewPager = (ViewPager) getActivity().findViewById(R.id.view_pager_1);
viewPager.setVisibility(View.GONE);
And to set it as visible just replace GONE with VISIBLE.

android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="50dp"

app:tabTextColor="#color/empty_area"

android:layout_width="match_parent"
android:layout_height="3dp"

</RelativeLayout>
The other way, as you mentioned is to put the tab layout inside the AppBarLayout in app_bar_main.xml

CollapsingToolbarLayout not work with ViewPager and WebView

I want to collapse toolbar in my activity when I scrolling WebView inside fragments (ViewPager). Using support library 22.2.1.
What am I doing wrong?

app:layout_behavior="#string/appbar_scrolling_view_behavior">
<WebView
android:id="#+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
Please, help.

Put your ViewPager outside and below the AppBarLayout.
