Menu
I am trying to show scroll bar in my edit text only when height of my edit text reach at the end of my layout height. That's working fine if i am entering/adding blank space but its causing problem when I my text reaches to end of my edit text width. Once my text reaches to end of my edit text width it start showing me scroll bar whereas it should show up when i reach to (height)end of screen.
Please advice how can i resolve this issue. Please find attached image and code for reference.

A ConstraintLayout is a ViewGroup which allows you to Position and size Views in a flexible way. It is basically RelativeLayout on Steriods. The Views will be positioned and sized w.r.t other Views with the Use of Constraints.
You can make your activity scrollable using ScrollView. Its very simple and effective to use. Just copy code of ScrollView from below and paste it in your layout xml file. You can use this ScrollView with Linear as well as Relative Layout also.
This might help I have edited a few things in the code. I have removed the barrier and changed it with a horizontal guideline and set that guideline to 80% of the screen height and the footer object aligned to that horizontal guideline. Kindly look the code below I hope it solves your problem. If you have any doubt about how I set the constraints I'll be happy to help.
