Add Divider to AlertDialog with CustomView

I'd like to add a divider to an alert dialog at the bottom, similar to the one it shows when there are long list views (see image).
However, I've added a customized view, because I want to be able to use a generic layout for all my AlertDialogs in the whole app. Now there is a very huge space between view and buttons. Additionally the listview, which used to have the divider (from the original AlertDialog view), is not available anymore and my layout has it's own recyclerview. (Because they are recommended nowadays.)
I tried adding a divider in my custom view, but this divider is bound to the padding of it's parent and therefore doesn't fill the whole dialog (and is still heavily spaced from the buttons).
So I'd basically like to access the area of the buttons in the alertdialog to add a divider at the top of this view. (Which then would be full width and below the padding of the custom view.) It would be great, if this was possible with the Builder, because I sometimes use positive and negative buttons and sometimes only negative or only positive and customizing all that in a generic layout as well would be a huge effort.
Here's my custom layout (with divider). I'm using the MaterialAlertDialogBuilder. Note: I could remove the padding at the bottom to remove the space, but then it looks smashed and the problem with the width of the divider still isn't fixed.

Goal:
Edit 1: It should also work with the recyclerview being filled, so it has to scroll, where the current solutions let the recyclerview disappear in the padding. There's 1 1/2 items left, but I can't scroll any further. (Image is without marginTop on Divider, with margin it actually disappears as well)
Solution:
If you don't have a scrolling recyclerview with many items, #shraddha patel s approach works just fine. However, if you have one, to avoid cutting off the last items, you need to use a LinearLayout instead of a ConstraintLayout for the contentview, as shown in this somewhat related bug report: https://github.com/material-components/material-components-android/issues/1336
However, if you have items below the recyclerview, the parent layout still needs to stay a constraint layout or the divider will disappear in scrolling lists.
So the working solution for me now is:

Vertically, the layout does what I want: it puts the last layout and fills the screen.
However, when the device is flipped horizontally, the bottom portion (the nested constraintlayout) disappears due to the constraint on itself of app:layout_constraintBottom_toBottomOf="parent"
"How do I fill the screen with a second layout while still having it scroll horizontally ?"
I have attached pics and a demo repository to isolate the problem.

I've found a solution. Instead of minHeight, you can use
app:layout_constraintHeight_min="100dp"

I want the TextView on top, followed by the CardView, followed by a ConstraintLayout, followed by the bottomNavigationView. Somehow the elements are stacked on top of each other like this:
I made sure that every element are constrained to the top or bottom of the next element respectively. Still they end up on top of each other. Is there a better way or a fix to this problem?

In card view you added two constraint on top: remove app:layout_constraintTop_toTopOf="parent" and will work.

You don't need to constraint TextView to Carview, only CardView to TextView.
If TextView width is match_parent, you don't need to set right constraint. Only top and left.
remove CarView to parent top constraint
you don't need to constraint CardView to Container, only container to CardView

View with minHeight in ConstraintLayout

I have a ConstraintLayout inside a NestedScrollView. The ConstraintLayout contains a bunch of views but the last View can have a dynamic height to fill up the bottom space if there is any but it also needs to be a minimum height if there is not enough space.
For arguments sake, here is an example.
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:layout_height="match_parent">
<View
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintHeight_min="1500dp"
android:background="#color/red"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
</android.support.constraint.ConstraintLayout>
</android.support.v4.widget.NestedScrollView>
As you can see I have put the ConstraintLayout version in but it doesn't work. Obviously the values are ridiculously large but this is just for testing.
If I don't set fillViewport="true" on the NestedScrollView then ConstraintLayout has a height of 0. When I do set the fillViewport, the ConstraintLayout does not scroll but just fills the screen.
How can I set the View so that it expands to the bottom of the ConstraintLayout which should be as big as the Viewport but if my View is not of the minHeight then we allow scrolling?
I am using version 1.0.2 of the ConstraintLayout library.
What I expect to see is the being all the way to the bottom of the parent but if that size is less than 1500dp then the view scrolls.
I have entered 1500dp like so android:layout_height="1500dp" and the view scrolls accordingly.
UPDATE 1
Seems to be once I put the layout within a FragmentViewPager. The app:layout_constraintHeight_min property isn't respected and it only matches the height of the viewport.
I also tried taking the NestedScrollView out of the fragment and putting the ViewPager inside it but again didn't work.

Add this attribute to the view you'd like to have stretch:
app:layout_constraintHeight_default="spread"
I made a tiny app to demonstrate. No java logic to speak of, but here's the layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView

android:background="#fff"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toTopOf="#+id/two"/>
<TextView
android:id="#+id/two"
android:layout_width="0dp"
android:layout_height="48dp"
android:gravity="center"
android:text="hello world"
android:background="#eee"
app:layout_constraintTop_toBottomOf="#+id/one"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toTopOf="#+id/three"/>
<TextView
android:id="#+id/three"
android:layout_width="0dp"
android:layout_height="0dp"
android:gravity="center"
android:text="hello world"
android:background="#ddd"
app:layout_constraintHeight_default="spread"
app:layout_constraintHeight_min="300dp"
app:layout_constraintTop_toBottomOf="#+id/two"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toBottomOf="parent"/>
</android.support.constraint.ConstraintLayout>
</android.support.v4.widget.NestedScrollView>
The bottom view stretches to fill the viewport when it is smaller than the remaining available space, and scrolling is impossible:
The bottom view maintains a fixed height when it is larger than the remaining available space, which makes scrolling possible:

I am using com.android.support.constraint:constraint-layout:1.0.2 and this works for me:
<android.support.v4.widget.NestedScrollView 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:orientation="vertical">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:background="#drawable/gradient"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHeight_min="1500dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
</android.support.v4.widget.NestedScrollView>

As the first thing is we have to specify the fixed height to each text view or used wrap content as another option.Secondary inside constraint layout the property app:layout_constraintHeight_default="spread" helps the last view to get the remaining complete space left and if no space left then automatically synced to scroll view.

Content of View not shown completely when using a ConstraintLayout - Android

I am using this color picker above a guideline and want to align a Text View (and other views) below the guideline and bind them to the width of the color picker by using a ConstraintLayout with these options:
app:layout_constraintRight_toRightOf="#+id/colorPicker"
app:layout_constraintLeft_toLeftOf="#+id/colorPicker"
(The width of the color picker depends on the available height.)
The problem I am facing is that the view seems to be placed exactly below the color picker, however, the content of the view is not adjusted and therefore not shown completely as shown in this picture.
Similar behavior can be reproduced with an ImageView instead of TextView.
A RecyclerView seems to be working, however, the 'list end animation' when reaching the start or end of the list is misplaced.
When using other views instead of this color picker I do not face this issue.
Can anyone explain this behavior and how to fix it?
The complete xml code I am using for this:
<android.support.constraint.ConstraintLayout
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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="xxx.xxx.xxx.MainActivity">
<com.rarepebble.colorpicker.ColorPickerView
android:id="#+id/colorPicker"
android:layout_width="wrap_content"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#+id/guideline"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
/>
<android.support.constraint.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintGuide_percent="0.60"
android:orientation="horizontal"
/>
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Hello World! Some chars in this TextView are cut on the right side."
app:layout_constraintTop_toTopOf="#+id/guideline"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toRightOf="#+id/colorPicker"
app:layout_constraintLeft_toLeftOf="#+id/colorPicker"
/>
</android.support.constraint.ConstraintLayout>

Did you try using LinearLayout? With problems like these, where one view needs to occupy a percentage of the screen, using layout_weight
Solution using LinearLayout
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="vertical">
<com.rarepebble.colorpicker.ColorPickerView
android:id="#+id/colorPicker"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_weight="6"
/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Hello World! Some chars in this TextView are cut on the right side." />
</FrameLayout>
</LinearLayout>
Edit based on comments
Something like this should work. You can change the View's visibility to GONE or VISIBLE depending on whether the FloatingActionButton has been tapped or not.
