Custom DataField tap not respond

You won't get the button bar. All you'll see is the tap. It's been quite some time since I looked at input to a data field, but you probably have an input delegate to look for onTap. and the tap is all you'll see. (and the x,y of the tap)

So how Can I exit from the activity if the Data Screen shows only my DataField on the 820 Edge?

Do you mean the button bar vanishes? I thought you were expecting to see it. What happens if you swipe?

If I swipe I will go to the next or prev Data Screen, but if I tap nothing happens. So in this moment I have to add always a 2nd Data Screen to be able to come back to the "Home".

I guess I still don't understand. You have a full screen DF where you want to handle tap for the second screen? Or just that when you tap the button bar goes away?

This is just conjecture, but if you have an input delegate with onTap(), are you returning false (not handled)? I assume if you return true (handled), then the default toolbar won't be displayed.

When I tap the button bar goes away, correct, it doesn't appear.
And I haven't implemented any InputDelegate.

Now it works thanks. I have implemented an InputDelegate and returned false onTap() as you suggested.

It kind of depends on what's happening (I still don't understand). Yes if you have a delegate to catch onTap, return false but if you don't have a delegate, is it just that you lose the button bar until you swipe to a different screen and come back?
