Evenly spread views inside a cardview Horizontaly

I need help, I have ConstraintLayout and a few child views, I also have a card view which is a child view of the ConstraintLayout, I need to spread it evenly 3 views on the card view using only one ConstraintLayout to keep the flat hierarchy

I have tried chain styles but no winning. Is it possible to achieve what I want to achieve using only one ConstraintLayout?

The main problem here is with your xml structure of the 3 views which are direct children of the CardView instead of a ConstraintLayout so any constraints attributes you apply there cannot work because the direct parent is the CardView.
Therefore your structure should look like this:
<androidx.cardview.widget.CardView>
<androidx.constraintlayout.widget.ConstraintLayout>
<TextView android:id="#+id/years_title"/>
<TextView android:id="#+id/coffees_title" />
<TextView android:id="#+id/bugs_title"/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>
Now to evenly spread the above 3 views in the ConstraintLayout horizontally you have to apply for each TextView the attribute app:layout_constraintHorizontal_weight="1", the android:layout_width="0dp" and link every TextView child with its neighbours eg. for the second TextView will be: app:layout_constraintStart_toEndOf="#+id/years_title" , app:layout_constraintEnd_toStartOf="#+id/bugs_title".
So your new structure of the CardView should look like the below:
<androidx.cardview.widget.CardView
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/job_title"
app:layout_constraintStart_toEndOf="#id/profile_image"
app:layout_constraintEnd_toEndOf="parent">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white">
<TextView
android:id="#+id/years_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#android:color/holo_blue_dark"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toStartOf="#+id/coffees_title"
app:layout_constraintHorizontal_weight="1"
tools:text="Years" />
<TextView
android:id="#+id/coffees_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#android:color/holo_orange_dark"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toEndOf="#+id/years_title"
app:layout_constraintEnd_toStartOf="#+id/bugs_title"
app:layout_constraintHorizontal_weight="1"
tools:text="Coffees" />
<TextView
android:id="#+id/bugs_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#android:color/holo_green_dark"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toEndOf="#+id/coffees_title"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_weight="1"
tools:text="Bugs" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>
Result:
Or in case you want the CardView to wrap to its content it should look like this:
<androidx.cardview.widget.CardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/job_title"
app:layout_constraintStart_toEndOf="#id/profile_image">

How to align TextView in two lines between images in ConstraintLayout

I'm doing some design in constraintlayout that is give me a pain. I have an image at the left, two text in a vertical orientation that is align at the end of this image and I have other constraints at right with an image and text.
If I type a long text in the two text that i have in a vertical orientation the text cover the constraint that I have at right of my view. That I want to do is if this text is long can't cover this constraint, have to expand to other line.
This is my code:

I recommend you use only one parent view and read about Guideline view, Constraints Chains and Barriers. So a possible solution could be the next:
And the code:
<?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="wrap_content"
android:padding="16dp">
<!-- In the parent constraint group add your custom background -->

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />

app:layout_constraintStart_toStartOf="#id/image_undo"
app:layout_constraintTop_toBottomOf="#id/image_undo"
tools:text="Ree" />
</androidx.constraintlayout.widget.ConstraintLayout>

First, you don't need two nested constraint layouts, one is enough.
Then just set the text with endToStartoOf image_undo and set the width to 0dp instead of wrap_content

Just do this:
<TextView
android:id="#+id/txt_subtitle_animation_native_cart"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_marginEnd="4dp"
android:maxLines="2"
android:textColor="#color/app_grey_medium"
android:textSize="12sp"
app:layout_constraintStart_toStartOf="#+id/txt_title_animation_native_cart"
app:layout_constraintTop_toBottomOf="#+id/txt_title_animation_native_cart"
app:layout_constraintEnd_toStartOf="#+id/constraint_undo_button"
tools:text="Subtitle asfda sdfowei oiwue rpoweiru oiwue twoeiu t oiweu t" />

Autosize a multiline textview in a ConstraintLayout

I'm trying to get a TextView which could be multiple lines tall and with the minimal width needed large.
I tried a wrap_content width, but the TextView stays on a single line and overlaps parent if the text is too long.
Then, I put the width to 0dp, and layout_constraintWidth_default to wrap.
That's almost perfect, but if the text is too long for a single line, the TextView takes all the remaining space.
Here's what I have and what I'd like to have :

How to layout 2 textviews in a custom compound constraint layout

I'm trying to give two Textviews the correct position in the Constraintlayout in my layout file. The problem is the textviews needs to be scalable using app: autoSizeTextType="uniform". To make them scale I also have to match_parent on the layout_width and layout_height. This makes the two textviews overlap. How can I accomplish the desired result?
Current XML file:
<?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="match_parent"
android:background="#color/colorPrimary"
android:gravity="center"
android:orientation="vertical">
<TextView
android:id="#+id/title"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="1"
android:textColor="#4689C8"
android:textStyle="bold"
app:autoSizeTextType="uniform"
app:layout_constrainedHeight="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.362" />
<TextView
android:id="#+id/message"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="ABC"
android:textColor="#4689C8"
android:textStyle="bold"
app:autoSizeTextType="uniform"
app:layout_constrainedHeight="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />
</android.support.constraint.ConstraintLayout>
Actual result:
Both textviews scales, but overlaps, and are placed in the center of the constraintlayout.
The current state:
The expected result:
One textview centered in the middle. One textview aligned at the bottom. Both textviews scales with the constraintlayout.
Expected result: (3 different custom compounds in an activity)

you have to give top and bottom proper constraint
<androidx.constraintlayout.widget.ConstraintLayout

Textview size we have to add

Modify the TextView to have height and width of 0dp, this will match parent constraint view, add in a constraint for the views in relation to each other and that should give you as you asked for
<TextView
android:id="#+id/title"
android:layout_width="0dp"

Horizontal buttons with max width and weight

I want to have two horizontal buttons with the first one taking 60 % of the layout width and the second one taking 40%. Both buttons have a max width for very large screens and in that case it has to be left aligned.
I tried with LinearLayout as shown below. But I am not sure if max width would work with weight. What is the correct way of implementing this?
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="40dp"
android:orientation="horizontal"
android:weightSum="1"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#id/eventTitle">
<Button
android:id="#+id/one"
android:layout_width="0dp"
android:layout_height="80dp"
android:layout_weight=".6"
android:maxWidth="547dp"
android:text="One" />
<Button
android:id="#+id/two"
android:layout_width="0dp"
android:layout_height="80dp"
android:layout_marginLeft="32dp"
android:layout_weight=".4"
android:maxWidth="349dp"
android:text="Two" />

The attribute maxWidth should be set in your LinearLayout:
<LinearLayout

Remove it from your child views and the corresponding weight will be used.

I think the requirement is like below image :
Here is code to achieve the same :
<android.support.constraint.ConstraintLayout
android:id="#+id/main_content"
android:layout_height="match_parent"
android:layout_width="match_parent">
<android.support.constraint.Guideline
android:id="#+id/guideline"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.6" />
<Button
android:id="#+id/button1"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginLeft="16dp"
android:layout_marginRight="8dp"
android:layout_marginStart="16dp"
android:layout_marginTop="16dp"
android:layout_width="0dp"
android:text="Button"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="#+id/guideline"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/button2"
android:layout_height="wrap_content"
android:layout_marginEnd="16dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="16dp"
android:layout_marginStart="8dp"
android:layout_marginTop="16dp"
android:layout_width="0dp"
android:text="Button"
app:layout_constraintLeft_toLeftOf="#+id/guideline"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
