Android Studio Missing Constraints???

Hiya Everyone!

I am doing my Login xml file and I was given loads of errors to which I solved by clicking on the light bulb’s suggestions. The line added to my text views, edit texts and my buttons represents the following:




When I run the application, ALL my features are situated on the top left of the screen tough I wanted them in the center. Could you tell me if this has somthing to do with it? Thank you very much! 


All that is doing is suppressing the warning. I would recommend using a relative layout.
