ScrollView Overlaps content in fragment - android

In this fragment as soon as try to scroll the contents start overlapping on each other.
This fragment opens immediately after a Splash Screen Activity. when I try to input something in first edit text and then scroll at that time all the things overlap on each other. The overlapping takes place only when I try to scroll. Please Help

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"
More details here.

Why is my view stretching over list view boundaries?

The problem consists of, in this case, two views going out of planed boundaries of a list view. First of all the whole list view should be under the text view:
app:layout_constraintTop_toBottomOf="#+id/tptp"
Second, right side of the view stretches out of screen even though its width is set to match_parent.

app:layout_constraintTop_toBottomOf="#+id/total" />
</androidx.constraintlayout.widget.ConstraintLayout>
The problem is that when i try it on a smaller screen phone, it cuts off some of the objects from the bottom of the activity. How can i make it resizable so it can fit any screen size? Every object is constrained Top-To-Bottom of the object above it.

You can use ScrollView, so the user can scroll down and see the whole activity. Just wrapping your ConstraintLayout in ScrollView should be enough, like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

Anyways, you should use wrap_content and match_parent instead of hard-coded sizes. Your layout needs to be flexible and adapt to different screen sizes, and that's not possible if you're using determined sizes in your layout. Please take a look into Android Developer: Support different screen sizes

Solver for ConstraintLayout doesn't measure include correctly

I'm currently practicing UI designing in Android and needed to make a layout be included in multiple layouts as a header. So I made this quite complex layout below.

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

Android Studio: Difference in the layout between Preview and Simulator mode

I am just new diving into Android app development world and created recently my first calculator app. When I run the app on the simulator, I saw a problem that there is a difference between the layout in the Preview mode and the one in the Simulator mode, as you can see below:

ok , you need to use linear layout with weight to do this ,, try this code ..
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:weightSum="7"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<TextView
android:id="#+id/textView3"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" android:text="of"
android:textSize="24sp"
tools:layout_editor_absoluteX="181dp"
tools:layout_editor_absoluteY="255dp" />
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" android:text="%"
android:textSize="24sp"

<EditText
