Issue
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!

Solution
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"
