[semi-solved] Android Studio - XML looks nothing like the layout when emulated?

[TheTurtleKing]

So, uh, title explains it. 

 

Whenever I try to emulate my xml layout on a Pixel emulator, everything gets all bunched up.

what did I do wrong?

halp

update: added

android:gravity="center"
android:layout_gravity="center"

to lines 8 and 9.

 

still no luck so I deleted those lines.

Interesting observation....

 

I changed the theme to material dark but the emulator didn't change?

[TheTurtleKing]

I somewhat solved it. 

I had to "infer constraints" on all of the stuff. more here : 

 

Still though, theme isn't really working.

The XML Source you posted had just the constraints for the correct rendering in the design view in Studio. It was missing the correct layout attributes like app:layout_constraint.... The constraint attributes prefixed with tools: just contain absolute positions for the layout editor. 

For your theme issue, try to change the theme inside your AndroidManifest.xml  and rebuild your project. This should solve your issue
