My views get messed up on screen rotation. The data I enter in edit-text does not get erased. How could I handle my views on screen rotation? without rotation

I don't want to fix the orientation of my app. i.e.:-
setRequestedOrientation ( ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ) ; or android:configChanges= " keyboard|keyboardHidden|orientation"
Only use two layouts for each screen orientation in case you really need a different layout for both cases. I suppose that in your case is much better to have one layout that adjust to both cases.
When working with layout, consider using ConstraintLayout because it adjusts for all screen sizes and cases. Trust me, when I was using RelativeLayout and I was laze to learn about ConstraintLayout, I was being dumb because with ConstraintLayout you will gain a lot of time. Imagine coding one layout that will adjust to more than 20 screens.
For your case, you can use this code:
