I am trying to split screen in android and trying to overlay a button on top of divider
Below is the current and expected
Below is my XML layout file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF0000"
android:weightSum="2">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#ff0000" />
<RelativeLayout
android:background="#00ff00"
android:layout_height="0dp"
android:layout_width="match_parent"
android:layout_weight="1">
<ImageButton
android:id="#+id/imageButton"
android:layout_width="90sp"
android:layout_height="90sp"
app:srcCompat="#drawable/exchange"
android:layout_centerHorizontal="true"
android:layout_marginTop="-45dp"/>
</RelativeLayout>
</LinearLayout>
You can achieve this by aligning the layout in an ordered way or also by using the Constraint Layout.

Probably the simplest way to take what you have and make it work would be to use a FrameLayout to wrap your existing layout:
<FrameLayout
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">
<!-- your current LinearLayout goes here, except for the ImageButton -->
<ImageButton
android:id="#+id/imageButton"
android:layout_width="90sp"
android:layout_height="90sp"
android:layout_gravity="center"
app:srcCompat="#drawable/exchange"/>
</FrameLayout>
The android:layout_gravity attribute is the key here; that will float your button in the center of the screen.
While the above will work, I'd recommend using ConstraintLayout instead:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
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="#FF0000"
android:orientation="vertical">
<RelativeLayout
android:id="#+id/top"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#ff0000"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#+id/bottom"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"/>
<RelativeLayout
android:id="#+id/bottom"
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#00ff00"
app:layout_constraintTop_toBottomOf="#+id/top"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"/>
<ImageButton
android:id="#+id/imageButton"
android:layout_width="90sp"
android:layout_height="90sp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:srcCompat="#drawable/exchange"/>
</androidx.constraintlayout.widget.ConstraintLayout>
By doing it this way, you flatten everything into a single view group.
<RelativeLayout 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">
<LinearLayout
android:id="#+id/topView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
</LinearLayout>
<ImageButton
android:id="#+id/imageButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
app:srcCompat="#android:drawable/btn_dialog" />
<LinearLayout
android:id="#+id/bottomView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
</LinearLayout>
</RelativeLayout>
I'm using recyclerview that loops the images but it starts behind the actionbar as shown below. I wanted the image to appear starting below of the action bar. I tried using the android layout below but still doesn't. Any solution guys? Thanks !!!!

How you can see, there is NestedScrollView with app:layout_behavior="#string/appbar_scrolling_view_behavior"
And regardless of the fact, has NestedScrollView this tag or not, Coordinator doesn't hide Toolbar.
Where is error in this code?
You are not using "CollapsingToolbarLayout"
Doc says:
CollapsingToolbarLayout is a wrapper for Toolbar which implements a
collapsing app bar. It is designed to be used as a direct child of a
AppBarLayout.
For your understanding refer below example
