App Android ScrollView with form

by maluss   Last Updated December 07, 2017 10:16 AM

I'm a developer creating an android application and I got a question about UX. I got a scrollable activity that will show some informations. The user can just validate or refuse the activity.

Something like that

For validate or refuse the user have to enter a comment about why he chooses to validate or refuse.

Ok so what is the best option to do this ? For now when the user press the button validate he have a dialog pop up that ask him the reason. But maybe i have to do something else like set the validate and refuse button to grey until the user enter a comment, the field will be in the scrollable view ? Or maybe when the user will presse the button he will stay on the activity that will scroll until the comment field that will appear in red ?

Thank you and sorry for my bad english
