Making ImageView take up size of container

I'm trying to create the following layout:
Where after a certain device width, the container will only be a certain width and will not increase in size anymore, here it is set at 400dp. If the device is less than 400dp, then it will get the width of the device instead. The imageviews inside, should be half the width of the container. The container should also be centered after 400dp.
My current code doesn't center the container and it chops off the second image and the text on the right. How can I fix this?

Use a Guideline in the project which runs through the middle of the layout
Code Snippet
<androidx.constraintlayout.widget.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5"/>

android:layoutMargin ="16dp"
app:layout_constraintStart_toStartOf="#id/guideline"

android:src="#drawable/landscape"/>
<ImageView
android:id="#+id/postImgB"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="#id/guideline"
android:layoutMargin ="16dp"
android:adjustViewBounds="true"
android:scaleType="centerInside"
android:src="#drawable/landscape"/>
then attach the images to the guideline and then to the parent give a margin to each. Use "0dp" or match constraints for it to mimic the image.

How to design a recyclerview with each item containing 2 buttons beside an imageview in andorid

I am trying to make a recyclerView where each of the items in the list will show an imageView with 2 buttons on the right of the imageview. I have tried but not really getting there. Some help would be really great.
Here is what i want:
What i tried:
<?xml version="1.0" encoding="utf-8"?>
<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="wrap_content">
<ImageView
android:id="#+id/imgVw_contact"
android:layout_width="0dp"
android:layout_height="#dimen/album_cover_height_details"
android:layout_margin="5dp"
android:layout_marginStart="4dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="4dp"
android:layout_marginBottom="8dp"
android:clickable="true"
android:scaleType="fitXY"
android:src="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="1.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/txtVw_contactName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/imgVw_contact"
android:layout_marginStart="8dp"
android:layout_marginEnd="8dp"
android:gravity="center"
android:text="myColors"
android:textColor="#color/album_title"
android:textSize="#dimen/album_title"
android:textStyle="bold"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/imgVw_contact" />
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:background="#drawable/ic_newok"
app:layout_constraintBottom_toBottomOf="#+id/imgVw_contact"
app:layout_constraintEnd_toEndOf="#+id/imgVw_contact"
app:layout_constraintHorizontal_bias="0.931"
app:layout_constraintStart_toStartOf="#+id/imgVw_contact"
app:layout_constraintTop_toTopOf="#+id/imgVw_contact"
app:layout_constraintVertical_bias="0.409" />
</android.support.constraint.ConstraintLayout>
and the result is:
I cant find a reason for why the images are getting round.
Also I have tried to use a drawable for button background but no matter what i create either new image asset or vector asset it becomes huge when i use it as background(as you can see in the screenshot).

Here is the design you need using ConstrainLayout -
<?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="wrap_content"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginTop="5dp"

android:textStyle="bold"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#id/imgVw_contact" />
<Button
android:layout_marginTop="8dp"
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_clear_black_24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/btn"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_check_circle_black_24dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
The corresponding layout image is -

Ok I got it. I found out the reasons behind my issues.
issue 1: There is a ic_launcher.xml(anydpi) inside mipmap which is a round cornered one. So when I was setting ic_launcher as background it takes this one .
issue 2: the images used inside the buttons get the full height width of button and becomes huge.

I have see your layout . and try to make it . Here is the code
Try this
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="200dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
android:src="#drawable/house1" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_alignParentRight="true"
android:paddingRight="5dp"
android:layout_centerVertical="true">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_highlight_off_black_24dp"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_vpn_key_black_24dp"/>
</LinearLayout>
</RelativeLayout>
</LinearLayout>

Change object width and height without hard-coding xml values

I am creating a home page for my android application in Android Studios. In the layouts folder I have my home page activity XML file. The home page will contain 3 clickable "boxes" which are CardViews. They are functioning correctly but I am working to change the CardViews sizes without hard-coding XML width and height (or other objects in the future). So that the sizes change properly according to different screen sizes.
In this specific case I want to increase the height of the CardViews.
Capture Receipt and Create Invoice CardViews I want to modify size of.
I am using a Linear Layout inside a Constraint Layout. The CardViews layout_width and layout_height are selected to match parent. I have modified the layout_weight, but this does not get the result I am looking for. I want to increase the heights without increasing the width.
Is this something to be done in XML or the Java part of the code?
Here is my home page activity XML code (without the Bottom Nav bar and Add Item part):

How is it possible to modify the heights and widths (just like you would when hard coding the XML) without hard-coding?

Gap between imageviews in Linear Layout that is inside the Constraint layout

I have 2 imageviews in a linear layout inside a constraint layout. There should be no gap between them, but when I run it, on some large devices it shows the gap even though I didnt give any margin or padding between them. The imageviews are with ids onboarding_image and image_line. I linear layout must be between the two guidelines showing images one upon the other without any space should take up whatever the space is left between the guideline in all devices.

You say: I didn't give any margin or padding between them.
However, I can see android:layout_marginBottom="-8dip". I know you are setting also android:layout_marginTop="-8dip" to the other image. It's a little weird.
If you want to make your Images fill all the contents, use:
android:scaleType="fitxy"
or
android:scaleType="centerCrop"
in both images

Why does my layout ignore Constraint Layout Guideline?

I am having a Guideline in a Constraint Layout that I use to anchor a LinearLayout to keep to its left as follows:
So, you can see the Guideline a bit right to middle and between LinearLayout on the left and the ImageView to the right.
Now, when I run the App and set the text of Skill Set or Tutor Types or Location considerably large, it crosses the GuideLine to being behind the ImageView as follows:
(Note: This is NOT a real person's data but mock data)
If you see the XML, you will find that the LinearLayout is indeed meant to be anchored to_left_of the Guideline but that doesn't happen.
So, what is the problem here? Is there a bug in Constraint Layout or am I missing something?

Change the android:layout_width="wrap_content" property of the LinearLayout to android:layout_width="0dp".
This will work because setting the layout_width to 0dp means that the width for the LinearLayout will be computed based on the constraints placed on it. Whereas if the width is set to wrap_content the width will be computed based on the size of it's child views.
