Bottom item cut in reyclerview in android

Hey I am working in constraint layout with recylerview. My bottom item is cut in the screen. I read this stack overflow post. I don't want to use relative layout or linear layout. Can someone guide me how to fix this in constraint layout.

My view cut from
UPDATE
#Zain after your suggestion i tried in my xml any my HorizontalScrollView is going behind my RV. I am adding my blueprint and you can see clearly that, HorizontalScrollView is going behind. After removing app:layout_constraintBottom_toTopOf="#+id/exploreList" from the HorizontalScrollView.
2nd suggestion try

Disclaimer Using a wrap_content height with vertical RecyclerView
can have impact on performance in terms of recycling views; specially
if the height is going to change frequently. Check this article
for more illustration.
So, the first step is to designate the RecyclerView height or to constraint it; from the constraints you want it to expand to the bottom; so use 0dp for that. But in order to make the minimum height to wrap content of the RecyclerView (in case that the items don't exceed the screen height); you can set the default height constraint to wrap with app:layout_constraintHeight_default="wrap" constraint.
Then remove app:layout_constraintBottom_toTopOf="#+id/exploreList" from the HorizontalScrollView, this actually made the bottom item of the RV hide (your main issue); because it is an over-constraint; the HorizontalScrollView tends to push the RV to the bottom while the RV tends to push the HorizontalScrollView to the top.
This will solve the main issue; but when the items are fully accommodated by the screen (no scrolling in the RV), then it will be biased in the middle; to fix this use the bias with app:layout_constraintVertical_bias="0.0" to be biased to the top.
Adding this in place into the layout:

Constraintlayout Vertical Bias not working in two views Android

I am using constraint layout with a vertical bias to fill view in recycler view. I successfully did that.
<?xml version="1.0" encoding="utf-8"?>

My recyclerview items showing me in reverse order because I want to make chat application. So I added reverseLayout and stackFromEnd true. So it look like this.
If my item is single my ui convert into like this by above xml code
Now I want to add edittext and button in bottom. Its not working vertical bias. Does any one know how to fix. Any suggestion to what can i use

UPDATE
After adding #MartinMarconcini answer it fixed my Scenario 2. I want to fix as Scenario 1 as well.

The idea is that your RV will handle its own item size and space by itself. You don't need to worry about this.
The Remainder of the space, will be used by ConstraintLayout.
So you need to pin the RV and the "Bottom Container" together. This would by default cause the CL to try to pull and balance layouts, so you have to tell the bottom container to be biased at the bottom.
In pseudo-XML:
<ConstraintLayout>
<RecyclerView
width=0dp
height=0dp
start/end = parent
TopToTop=parent
BottomToTopOf=BottomContainer
>
<BottomContainer>
width=0dp
height=wrap_content
TopToBottomOf=RecyclerView
BottomToBottomOf=parent
start/end = parent>
</ConstraintLayout>
Now this needs one more thing, because the RV would take all the space, you want to ensure the BottomContainer has more information about where it wants to be placed.
So you add:
app:layout_constraintVertical_bias="1.0"
to the Bottom Container.
This means, vertically, as "bottom" as you can. (0.0 would be the opposite).
The end result is:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingBottom="10dp"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"

app:layout_constraintStart_toStartOf="parent"

android:layout_width="0dp"
app:layout_constraintVertical_bias="1.0"
android:layout_height="wrap_content"
android:id="#+id/bottomContainer"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/recylerview"
app:layout_constraintBottom_toBottomOf="parent">
<EditText
android:id="#+id/editTextContainer"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="#+id/button"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="#+id/editTextContainer"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
Which looks like this:
UPDATE
If you add both
app:stackFromEnd="true"
app:reverseLayout="true"
It works the same way, except the item "0" is at the bottom, and the "last" item is at the top. Adding another item would add it at the top but the BottomContainer has no participation (or influence) over this:

Android WebView overlaps with other views

I have a simple web view in between image and button. For some reason, if I put a long text, the web view is overlapping with the logo and the button. It works for a short text. I used constraint layout. It seems that the web view is expanding beyond the parent view.
Please see the pictures.
Below is my layout code:

The problem lies in here:
<androidx.cardview.widget.CardView
android:id="#+id/cv_splash_screen"

android:layout_width="match_parent"
<-- change layout:height from wrap_content to some specific height let it be 300-400dp -->
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/card_normal_outer_margin"
android:layout_marginTop="#dimen/card_normal_outer_margin"
android:layout_marginRight="#dimen/card_normal_outer_margin"
android:layout_marginBottom="#dimen/card_normal_outer_margin"
app:layout_constraintBottom_toTopOf="#id/btn_cta"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#id/iv_logo">
or the second option is you can use minHeight and maxHeight in your cardview or it's child layout which is Constraint layout to prevent it from expanding on full screen
and if you have long texts to read use ScrollView inside cardview.

As you have set the height of your CardView to wrapContent it will expand to the content that is put in it, what you can do is set app:layout_constrainedHeight="true" that will prevent it from expanding beyond its bounds.
Note that you do have to set up the view bound chaining properly for this to work, ie set app:layout_constraintTop_toX and app:layout_constraintBottom_toX on all the views in the 'chain' from the top of the view through to the bottom.
so in your code:
<androidx.cardview.widget.CardView
android:id="#+id/cv_splash_screen"
style="#style/CardTheme"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/card_normal_outer_margin"
android:layout_marginTop="#dimen/card_normal_outer_margin"
android:layout_marginRight="#dimen/card_normal_outer_margin"
android:layout_marginBottom="#dimen/card_normal_outer_margin"
<!-- add this line --> app:layout_constrainedHeight="true"
app:layout_constraintBottom_toTopOf="#id/btn_cta"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#id/iv_logo">

Included ConstraintLayout deosn't fix position when TextView has two lines

I've got ConstraintLayout which contains TextView and includes other ConstraintLayout. The reason why I include other constraint is that in this project I'm using an old version of support library(26.1.0) which doesn't contain groups and currently I'm not able to upgrade it.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/topTitleTextView"
style="#style/TextBigMinus"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/margin_normal"
android:layout_marginRight="#dimen/margin_normal"
android:layout_marginBottom="#dimen/margin_normal"
android:gravity="center_horizontal"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0" />
<include
android:id="#+id/included_part"
layout="#layout/included_part"
android:layout_height="0dp"
android:layout_width="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/topTitleTextView"
app:layout_constraintBottom_toBottomOf="parent"/>
</android.support.constraint.ConstraintLayout>
I'm setting my text straight from the code and on different devices, it can have one or two lines. When it has two lines, the included part will be moved by the height of the line but should be resized as it has an app:layout_constraintBottom_toBottomOf="parent".
What causes that and how it could be fixed?

try to remove app:layout_constraintBottom_toBottomOf="parent"
and set android:layout_height="wrap_content"

This should work fine as per your requirement
<android.support.constraint.ConstraintLayout xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/topTitleTextView"
android:layout_width="0dp"
android:layout_height="0dp"
android:gravity="center_horizontal"
app:layout_constraintBottom_toTopOf="#+id/included_part"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0" />
<include
android:id="#+id/included_part"
layout="#layout/included_part"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/topTitleTextView"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

Since you want the included part to move as the height of the text line changes also get resized to fit in the available screen, having the app:layout_constraintBottom_toBottomOf="parent" won't work on layouts that include views (TextView, ImageView etc), nested included layouts with fixed height values in dp or sp unit. Make sure the included view has every height attribute set to 0dp inside ConstraintLayout and then use this code where I've fixed the constraint fields:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/margin_normal"
android:layout_marginRight="#dimen/margin_normal"
android:layout_marginBottom="#dimen/margin_normal"
android:gravity="center_horizontal"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.0" />
<include
android:id="#+id/included_part"
layout="#layout/included_part"
android:layout_height="0dp"
android:layout_width="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/topTitleTextView"
app:layout_constraintBottom_toBottomOf="parent"/>
</android.support.constraint.ConstraintLayout>

The text view bottom is constraint to parent, while the included part bottom also constraint to parent. This will resulted of some part of the view overlap each other. Try to remove app:layout_constraintBottom_toBottomOf="parent" on the text view property.

Hope it helps :)

In your first CircularImageView there's a problem with your right constraint:
app:layout_constraintRight_toRightOf="#+id/iv_prof"
This should be constrained to the left of iv_prof:
app:layout_constraintRight_toLeftOf="#id/iv_prof"
If you want the to be closer together in the center then change the style of the chain to packed by adding this attribute to the first CircularImageView:
app:layout_constraintHorizontal_chainStyle="packed"
To center the Views vertically in the parent you need to constraint the top and bottom of each View to the top and bottom of the parent respectively.
Also you're using left/right constraints for some Views and start/end for others. Try using just one set of them across the whole layout.

It worked for me using bias:
<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:layout_gravity="center">
<ImageView
android:id="#+id/img_splash_logo"
android:layout_width="200dp"
android:layout_height="200dp"
android:src="#drawable/weather_logo"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
