Android Question How can I drag a view to expand a panel

[tsteward]

Attached is a sample app. It shows a webview with a button below it.
Clicking the button hides the webview, moves the button and displays a panel.
Clicking it again reverses the process.

It works but it's ugly.
How might I go about making it draggable and work in both B4A and B4I

I considered AS_DraggableBottomCard but it seems to have a halfway or fully open setting
I would like it closed or even better closed to the bottom of the view above (in this case its a webview for demonstration purposes)

but it seems to have a halfway or fully open setting

And where is the problem? set both values to the same value and the panel has only one height, set 2 different values and it can be extended 2x. If the user pulls it down, it is closed.

I don't really understand but will have more of a look later
