View is behaving fixed sized instead of dynamic sized based on screen using ConstraintLayout

I am trying to create a setting screen, below is the code and preview in Android Studio.
It has a couple of issues. The CardView with the scrollView layout is not working as it should
What I want is, my CardView to be adjusted in the middle of userDetailsLayout and logoutBtn with the spacing of #dimen/_20sdp. But it can be seen that its stretching all the way to logoutBtn,
If I use a small screen mobile, the CardView, also starts overlapping userDetailsLayout
It's like, its making CardView fixed size instead of variable-sized based on space. What should I do?
android:layout_margin="#dimen/_20sdp"
app:layout_constraintTop_toBottomOf="#+id/userDetailsLayout"
app:layout_constraintBottom_toTopOf="#+id/logoutBtn"
app:layout_constraintRight_toRightOf="parent"

Not 100% sure what you mean, but from the code I would suggest you to change:
android:layout_width="0dp"
android:layout_height="0dp"
when you specify height and width constraints on the view. Otherwise the constraints won't work. And btw. dont use so many nested layouts inside your constraintlayout. Every single layout will need a complete new measure and render process which slow down your app a lot. Please also look at Guidelines and ConstraintAspectRatio.

The issue is that the logoutBtn is within the same parent as your CardView. They both have
android:layout_margin="#dimen/_20sdp"
That's why they have the same width, they both align right and left to the parent and have the same about of margin. So if you want it to be 20dp from the CardView you either want to nest the logoutBtn in the cardview or simply make the logoutBtn have 40dp
<TextView
android:id="#+id/logoutBtn"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:layout_marginBottom="20dp"
android:background="#color/error_red"
android:gravity="center"
android:text="string/logout"
android:textColor="#android:color/white"
android:textSize="14sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toRightOf="parent"

How to use sliding up panel with bottom navigation view?

I am using this library for sliding up panel. I'm trying to use it with the bottom navigation view, for my music streaming app. I am trying to do something like soundcloud app. But I'm unable to achieve this and it shows like this I have two player views, one is mini player and another is the big player. My miniplayer of the slidingup panel goes below of the
bottom navigation view. I want it stay on top of the bottom navigation view. When I click on the miniplayer, slide up panel expands, mini player is gone the big player is visible and the bottom navigation is also gone.
Sorry for my bad english.

Thanks in Advance,
Alby

android:layout_below="#+id/login_title"
Here should be "#id/..." (whithout a plus sign), because it is a reference to an existing ID.

The error was fixed after removing the below from Edit Text field: android:layout_above="#+id/post" android:layout_below="#+id/node_scan"

I think what you want is for the TextView text to be center justified horizontally, in which case add
android:gravity="center_horizontal"
to your textViews

You can (and probably you should) use other layouts inside your parent relativeLayout. This way you simplify a lot the design and you avoid that all the design is dependant of one item (on your layout, if you remove one of the textViews most of the layout is repositioned, as they were relative to that textView)
A quick example of this with your code could be something like this:
<?xml version="1.0" encoding="utf-8"?>

(I removed the text, colors and images, but it looks similar to what you want)
Try playing around with different sub-layouts and it will make your life easier :)

Graphical layout

I would make the main layout be a relative layout.
The "My Profile" button would be the first object in the layout
The segment underneath that can be another relative layout in which you would specify the association of all the elements.
And the bottom map portion would be the map view
Within the second portion, use a mix of vertical and horizontal linear layouts to get the look you desire
