I would like to have the same as on the enclosed image with the scanning information widgets (progressbar, textview and button) to stay at the bottom of the screen. However when I run my app they go at the top of the screen when the ListView is empty.
I tried a lot of methods described in other topics, but I still could not make it work.
Do you have some suggestions about which layout I should use in this case?

This is the way I did it an app I worked on previously. Using a RelativeLayout as the main shell we are able to position elements in any way inside it.

android:background="#color/white"
android:orientation="vertical">

I would first simplify the layout by flattening it slightly. Removed the FrameLayout that holds the bottom Constraint.. Then made the listViewDevices constrain bottom to top of the bottom contraint layout (which i have called scanner)..
Looks correct in my layout editor.

I would rather prefer to add LinearLayout as root layout.
So when you scroll down or up then it will not scroll with your layout when its empty.
So when your listview is empty then also it will be in the bottom of the screen only.

Thank you for your answers but none of them works. Sometimes it looks fine in Android Studio but when I test my application on a real phone the widgets are displayed on top of the screen.
If I will find a working solution I will post it here.

What my layout file currently does:
My layout file after building an app looks like on the picture and before building
What I want it to do:
I want this info icon and "Basic calisthenics progression" to be on top on all devices without overlapping.
What I've tried:
I've tried to add CardView, moving from constraint layout to frame layout, etc, but nothing seems to work and recyclerView still overlaps the header.

I have added ConstraintLayout in RelativeLayout and I want that at the bottom of my RelativeLayout.So, it's proper when the app opens in full-screen mode but in default mode constraint layout cuts from the bottom.
I have checked this thing in the different scenario like if I put it on top it comes proper even in the default mode but when I align it to bottom it gets cut.
<RelativeLayout 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"
tools:context="org.cocos2dx.cpp.AppActivity"
android:id="#+id/cameraView">
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/control"
android:layout_width="match_parent"
android:layout_height="112dp"
android:paddingBottom="0dp"
android:layout_alignParentBottom="true"
android:background="#color/control_background">
<ImageButton
android:id="#+id/cancelBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginStart="30dp"
android:layout_marginLeft="30dp"
android:background="#android:color/transparent"
android:src="#drawable/close"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageButton
android:id="#+id/imageCaptureBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#android:color/transparent"
android:scaleX="1.20"
android:scaleY="1.20"
android:src="#drawable/capture"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.5" />
<ImageButton
android:id="#+id/reverseCameraBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|right"
android:layout_marginEnd="30dp"
android:layout_marginRight="30dp"
android:background="#android:color/transparent"
android:src="#drawable/reverse_cam"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.508" />
</androidx.constraintlayout.widget.ConstraintLayout>
</RelativeLayout>
So, here in ConstraintLayout when I keep
android:layout_alignParentTop="true"
It doesn't get cut from top like in the image
but when I give it to android:layout_alignParentBottom="true" it gets cut only in default mode of the app and I want this constraintLayout at bottom of the RelativeLayout
You can also use Constraint layout as Rootview like below.

Below is a screenshot of my gridView currently:
Even though I have centered the TextField inside the card, they are still pinned to the left. How do I fix this so that the Text is centered in the middle? It seems like once I add an item to a gridView, the gridView attributes overrule their children.
Here is my layout code:

Add android:gravity="center" in your textview like following.
<TextView
android:id="#+id/tvCategoryTitle"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:layout_marginBottom="8dp"
android:text="TextView"
android:gravity="center"
android:textAlignment="center"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/ivCategoryIcon"/>
use relative layout insists of ConstraintLayout.
use center_horizontal to the text view=true
Can you please try this and change your constraint layout ?

I have a layout that exceeds the view boundaries after applying all the margins I'm looking for. I read that applying a chain will make it keep the same ratios while packing all the elements inside the view boundaries.
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/Texto2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="dsadsadsadsadasd"
app:layout_constraintTop_toBottomOf="#+id/texto1" />
<TextView
android:id="#+id/texto1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="gggggg" />
<ImageView
android:id="#+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/tut_first_img"
app:layout_constraintTop_toBottomOf="#+id/Texto2" />
<Button
android:id="#+id/botao"

android:layout_height="wrap_content"
android:text="ggggggggggggggggggggg"
app:layout_constraintTop_toBottomOf="#+id/img" />
</android.support.constraint.ConstraintLayout>
This is what's happening without margins after all margins applied it will exceed the view screen. How can I compact it while keeping the ratios? Also, how can I center all views in a vertical line?

I hope it helps you, looking forward if any further help is required from my end.

Just copy paste it and let me know if it works.
I hope that the below mentioned code helps you in achieving your desired layout.

Screenshot (of the UI achieved by the above code):
The chain symbol (right most symbol; below the first view in the layout) can be used to toggle and thus apply different chain styles (as per your need), if you aren't familiar with ConstraintLayout.
I'm facing a strange situation, I have designed a fragment to include a ScrollView but when i go to another fragment and back from backstack
View is Converted to another view not ScrollView and screen items overlaps
fragment XML:

Note that ConstraintLayout Tag is closed but not appearing on the above
also you could check this GIF to see what happens it may help in investigating what is the wrong

I want to know the cause and how to solve it
