drag and drop between two fragments?

问题:

I have a particular requirement where i need to drag a element in one screen then another fragment becomes visible where i can drop the dragged view .

what is the best way to achieve this ? I am not sure how to achieve this behavior between two fragments .Thanks in advance!

回答1:

THE basics we need to understand is these constants for drag and drop both applicable for activity and fragments

DragEvent.ACTION_DRAG_STARTED

DragEvent.ACTION_DRAG_ENTERED

DragEvent.ACTION_DRAG_EXITED

DragEvent.ACTION_DROP

DragEvent.ACTION_DRAG_ENDED

now you need to make fragment VISIBLE ON DragEvent.ACTION_DRAG_ENTERED OR STARTED above calls are properly explained following links
