Create layout using only constraint layout and text view

I am new to android and constraint layout, can you please help me create this layout using only Constraint Layout and Text Views? Don't bother with text/color, just the layout itself.
This is what I have so far, layout seems ok but not quite like in the picture. I don't know if just the different resolution or aspect ratio.

Did some modifications in the margins of these two. Now, the layout is looking similar to the one in the image you showed:
<TextView
android:id="#+id/textView49"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginStart="10dp"
android:layout_marginEnd="10dp"
android:background="#android:color/holo_green_dark"
android:text="TextView"
app:layout_constraintBottom_toTopOf="#+id/textView50"
app:layout_constraintEnd_toStartOf="#+id/textView48"
app:layout_constraintStart_toEndOf="#+id/textView47"
app:layout_constraintTop_toBottomOf="#+id/textView45" />
<TextView
android:id="#+id/textView50"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginStart="10dp"
android:layout_marginTop="10dp"
android:layout_marginEnd="10dp"
android:background="#android:color/holo_green_light"
android:text="TextView"
app:layout_constraintBottom_toTopOf="#+id/textView46"
app:layout_constraintEnd_toStartOf="#+id/textView48"
app:layout_constraintStart_toEndOf="#+id/textView47"
app:layout_constraintTop_toBottomOf="#+id/textView49" />
You can further increase the margins but that's upto you.
Edit: I would suggest you playing with layout_constraintHeight_percent attribute to solve those height irregularities.

Problem placing TextView on ImageView using ConstraintLayout

I am using Constraintlayout and I want to place my Textview on my Imageview, it is supposed to look like this after I'm done: https://i.stack.imgur.com/mYAws.png but each time I add constraints to the texts(Vertically and horizontally), the texts disorganizes and goes totally from how I want it to be,
Sometimes even shifting my images. I have tried severally to adjust it well to no avail

</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.core.widget.NestedScrollView>

The answer is pretty straightforward. First you should delete this lines from both text views.
tools:layout_editor_absoluteX="254dp"
tools:layout_editor_absoluteY="415dp"
Then all you need to do is add constraints like this. Below are constraints for your image
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
And the constraints for your text view would be like this.
app:layout_constraintEnd_toEndOf="#+id/image_view"
app:layout_constraintStart_toStartOf="#+id/image_view"
app:layout_constraintTop_toTopOf="#+id/image_view"
Of course you can add different constraints for the image because i do not know how do you want to position the image view in the app. But if you want a text view to be inside the image like in the link you sent then the constraints for the text view will be always like this.

It's all about tools:layout_editor_absoluteX and tools:layout_editor_absoluteY for yours textView3 and textView4. Also i think you do not know for what namespace tools exist.

Check the example below; it shows you what constraints can be used to get in the direction of your layout goals.

How to use constraint layout so the card views are always in one place?

I am using a constraint layout and card views in it, but on different screen sizes the card views are not in the same place. I thought the idea of constraint is that you only have to arrange the card view for one time and it automatically aligns to the different device sizes. The first picture shows the screen I want to have on every device size and the other picture shows you the result of a different size where the CardViews are obviously not in the right place.
I already tried using guidelines but it doesn't help. Or is it better to use another Layout like RelativeLayout? But what's then the point of a ConstraintLayout?
Design as it should be
Result with different size
Thank you for your help!

You don't see your layout the same way on different phones because your cardviews dimensions are a fixed size , why is it bad?
Different phones got different screen size, in your layout you are using fixed size on your view (fixed size is 50dp for example) and the result is that what may look good on one screen (your android studio preview screen) will not look good on another screen (your actual phone).
How to fix it:
You can just use app:layout_constraintWidth_percent and app:layout_constraintHeight_percent on your cardviews to give the size in precents according to the screen.
Something like this:
<?xml version="1.0" encoding="utf-8"?>

In this example, I have 4 buttons that represent your cardViews.
They are all equal in size and will be responsive to all screen sizes.
This layout will look like this (the arrow points to the guideline, to make it more understandable):

For Future Visitors, Chains are the magical word when trying to simulate Linear layout form. using horizontal chains with vertical ones along with using dynamic View sizes as Tamir Abutbul mentioned should be the best practice.

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

How to position the image buttons in my android app with respect to the background for different screen sizes?

I am making an android app for which i need the 3 image buttons containing the location pointers to be placed along the road in the background in the positions shown in the screenshot. Unfortunately the image buttons change their positions on different screen sizes. Any help is appreciated.
This following is my XML code. For now for the sake of the screenshot i have manually given values to the margin of the buttons and also because i don't know any other way of doing it.

Give a try to constraint layout.They are great when it comes to resizing and placing components that should look same in all devices.You can find it here
Constraint Layout Code Labs
Alternatively you can design the screen for various devices.For that you don't need the dimen.xml file, since they can be tricky. You can be make different layout files layout-large,layout-land,layout-xxxhdpi,layout-sw700dp. You can find it here Supporting multiple Screens in Android
Mike's solution in the comments for using x and y coordinates can also be applied here, but for that instead of taking the x and y coordinate you can place an transparent view over your location images.Those transparent views will shift a bit as per the device resolution but they will be largely on place to take your click event

The above is the best i could do given the scenarios, let me know if this works.
Alternatively you could divide the image into 3 parts to have a anchor for the ll3,ll2 and ll1.That way no mater how much the image stretches the layouts will always be pinned at a particular position.
