Do I need to change my xml code for supporting all screen size android devices?

Question

I have created layout for different screen size and this is my xml code for default layout but so any one please tell me what I should do to support my layout for any screen si

Answer 1

I edited you XML so it may be a good start for learning how to use ConstraintLayout. Check a tutorial for ConstraintLayout (constraintlayout.com)

1. Don't use match_parent with ConstraintLayout we only have 0dp (match_constraint) and wrap_conent
2. Don't mess up the XML with unneccessary nested ViewGroups (LinearLayout)
3. When using margin or padding best to use numbers based on 8 (8 - 16 - 24 - 32 - ...)
4. Using a CardView for button is wrong, check MaterialButton documents at material.io
