I am creating a View and was looking for Android Material Design Guidelines for the type of component shown in the image below - but I have no idea what it is called. In UX what is the name for the component I have marked with a red square?
(The component being where you have lists of items on the left and right with buttons or drag/drop functionality to move items between them)
I had a search on Android-Arsenal, but I didn't find anything that gave me a clue
Note: the picture is for illustration (I know what it does but not what it is called)
In java I've seen it called a Dual List Box, in GXT it's called a Dual List Field. I looked around and can't find any reference to it in Android.
