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"

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:

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

How to make a fragment fit in a FrameLayout in all screen sizes?

I am developing an app where I want to show few fragments in a container(Framelayout) one after other. I want my fragments to fit in the framelayout without its parts going out of the screen.
I want this:
But Getting this:

So is there any possible way that I can make the fragment fit on any screen size and all of it is visible inside the framelayout.

Below code will help with your fragment.xml file.
You didn't provided more values files means color code, string file and other. So below are some changes from your file like drawable and value related data.

ScrollView wont scroll Completely

I'm trying to make a layout divided into two parts in which the lower part should be scrollable.But the scrollview wont scroll completely till the end.
I have tried using NestedScrollView.I have also already tried adding margins and padding to scrollview, constraint layout, last view in the scroll view.Button at the end is not reachable. view abruptly ends in the middle of the textview above that button.

Horizontal RecyclerView inside NestedScrollView, can't scroll vertically

I tried every combination of this, some people said it's a bug but I think it's something small I'm missing. With the follwing XML, I can't scroll at all, only the horizontal scroll works.
I have a side-scroll RecyclerView which I can drag left and right, but the page has more I items than can fit, hence the ScrollView.
At first I was aiming for a collapsable toolbar, but when I add CoordinatorLayout, the activity is just blank.
My XML:

Someone pleeeease for the love of god explain this sh*t to me.

Try adding setNestedScrollingEnabled(false) to your inner recyclerview.
https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html
setNestedScrollingEnabled
Enable or disable nested scrolling for this view.
If this property is set to true the view will be permitted to initiate
nested scrolling operations with a compatible parent view in the
current hierarchy. If this view does not implement nested scrolling
this will have no effect. Disabling nested scrolling while a nested
scroll is in progress has the effect of stopping the nested scroll.

1)xml
android.support.v4.widget.NestedScrollView
inner use LinerLayout
2)
recyclerView = (RecyclerView)view.findViewById(R.id.recyclerview_main);
recyclerView.setNestedScrollingEnabled(false);

If someone still facing this issue, please take care of 2 things:
Your NestedScrollView height should be match_parent. If you are using NestedScrollView inside ConstraintLayout you can achive this by following line of code
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
Add below line in your RecyclerView
android:nestedScrollingEnabled="false"
I hope it will save others time.
