There are several clickable views (buttons, checkboxes, etc) in my app. I want to familiarize the users with the purpose of some views, meaning why and when to use them. So that, I want to create one-time-only intro for some views.
I think the best way to do this is to highlight the view and at the same time show toast-like info-box.
Here's is the example of what I want to achieve (see below screenshot of Fabulous app).
In the above example the whole screen is covered by transperent gray background while checkbox and toast-like info-box is highlighted with white color.
How can I create similar transperent background highlighting some views?
