customize xml layout in android

I'm trying to make my search bar above my tabs but it appears behind it
This my xml file :

Honestly, this is not the best layout. Very expensive to measure all relative layouts wrapped to each other. Your elements appear behind each other because you made your view in relative which is very similar to frame layout. I think a better way to do it in ConstraintLayout. But if you want to make it in relative do it like that.

place your search layout below tab layout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.cloud.services.drmzr.MainActivity"
android:layout_below="#id/tab_layout">
<include layout="#layout/user_search"/>
</RelativeLayout>
check this line : android:layout_below="#id/tab_layout"

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
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:android.support.v7.cardview="http://schemas.android.com/apk/res-auto"

<TextView

<TextView

android:layout_width="wrap_content"

android:layout_below="#+id/tv_text"
android:layout_toRightOf="#+id/iv_image"
android:layout_toEndOf="#+id/iv_image"/>
</RelativeLayout>
</android.support.v7.widget.CardView>
</RelativeLayout>
Here is my activity_pendaftar.xml

android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/viewpager">
</android.support.v4.view.ViewPager>
</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.
<?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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<include
layout="#layout/toolbar_pendaftar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.design.widget.TabLayout
android:id="#+id/tablayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabMode="fixed"></android.support.design.widget.TabLayout>
</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>

Move your include statement outside the appbarlayout and align it to parent's bottom like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
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"
tools:context="com.martin.app.donorkuyadmin.PendaftarActivity"
android:background="#drawable/background4">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/tablayout"
app:tabMode="fixed"
app:tabGravity="fill">
</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/viewpager">
</android.support.v4.view.ViewPager>
<include
android:layout_height="wrap_content"
android:layout_width="match_parent"
layout="#layout/toolbar_pendaftar"
android:layout_alignParentBottom="true">
</include>
</RelativeLayout>

CoordinatorLayout adds space between AppBarLayout and RecyclerView

CoordinatorLayout adds space between AppBarLayout and RecyclerView. Not sure whether its the Toolbar or AppBarLayout.
Screenshot of the rendered layout on phone:
The design rendering on Studio doesn't how this space.
Any idea on what's going on?
The Code Itself.
