Using Margin or Padding with LinearLayout

I'm having trouble lining up a LinearLayout in a XML file. I'm trying to use a LinearLayout because I have TextViews that have to be hidden/shown upon certain options being selected, which I have that down. My problem is that I'm trying to use margin to line everything up centered, but if I run it on my Pixel 5 emulator, it's shift to the right when I have everything centered in my XML. Should I be using padding instead in my LinearLayout, or what should I be doing? Thank you!

You shouldn't center anything using just padding or margin. In your case it's enough to use the layout_gravity in each TextView:
android:layout_gravity="center_horizontal"

I am having trouble positioning views in a full screen android app

Hey thank you very much for that help and the code looks great but now I am just running into all sorts of problems... First I can not make a circle with the 2nd stacked ImageView, also I can not position the first 3 ImageViews to the top of the screen with 8dp of padding, it will literally not let me do anything without the whole thing becoming one big cluster. I have an image of what I am trying to achieve and will attach it. If you have any ideas all are welcome. Thank you very much by the way! enter image description here

Design-Output
Use https://github.com/hdodenhof/CircleImageView for Circle ImageView.
Add dependency in your app Level gradle file.
implementation 'de.hdodenhof:circleimageview:3.1.0'
Add or replace ImageView to your XML file.
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/profile_image"
android:layout_width="120dp"
android:layout_height="120dp"
android:src="#drawable/cybersecurity_1134x638"

app:civ_border_width="2dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.526"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
For Top Images I think you should check the height of the imageview Instead of wrap_content you can change with static value.

As you can see I have to set manually the images' layout_height, but I would like to get the best proportion for the pictures (adjust the images 15dp on top of the bottom toolbar). I have tried to use app:layout_constraintBottom_toBottomOf in the LinearLayout that contains these pictures, but when I click on the collpasible and the description is shown I need to scroll through the screen to see the pictures, but using app:layout_constraintBottom_toBottomOf the images simply disappear.
I know that app:layout_constraintBottom_toBottomOf should not be used in this case, but is there any other way to change the layout_height of my pictures to wrap_content and get the best size for them when I have to scroll down?
Basically, I want another option (besides app:layout_constraintBottom_toBottomOf) that will adjust the images 15dp on top of the bottom toolbar when I am scrolling down.
I would really appreciate if someone could help me with this.
Thanks!

I have inside this holder a ConstraitLayout that is disabled from view in a certain stage in my app.
As you can see, once I disable the ConstraintLayout from sight the inner RecyclerView gets cut in half.
here is the layout of the inner RV -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/very_light_grey"
android:orientation="horizontal">
<TextView
android:id="#+id/marketplace_cart_attribute_holder_attribute_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="#dimen/marketplace_14dp"
android:textSize="16sp"
tools:text="Attribute Name:" />
<TextView
android:id="#+id/marketplace_cart_attribute_holder_attribute_value"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="#dimen/marketplace_14dp"
android:textSize="16sp"
tools:text="Value" />
</LinearLayout>
What am I missing the causes the RV to get cut in half that does not happen when I have the bottom layout visible?

Add margin bottom -
android:layout_marginBottom="15dp"
to your LinearLayout to avoid the issue for a number of different screen sizes:
<LinearLayout
android:id="#+id/shopping_cart_holder_infobox_viewgroup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginStart="7dp"
android:layout_marginTop="15dp"
android:layout_marginBottom="15dp"
android:layout_marginEnd="0dp"
android:orientation="vertical">

Solved - I have a redundant marginTop in my LinearLayout.

In the layout editor, it looks fine. But when I compile my code, the ScrollView is clipping through the include without that much marginTop. I might file an issue if this is a bug.
From the suggestions below, I tried to change ScrollView to a NestedScrollView. As I have guessed, it still didn't work.
I also want to emphasized that my question is not about the RecyclerViews not being able to scroll, because I know that would happen, but about the clipping of the ScrollView through the include layout.

Change your include layout constraint like below
Remove bottom constarint and used NestedScrollView in main layout instead of ScrollView
