Sort – Drag & drop
It works like this:
The user presses the hard key for the options menu.
The Options menu slides into the screen. When the ‘rearrange’ function in the main menu is tapped…
… the drag & drop mode is accessed, that can be identified by a visual target, added to every list item and…
… a button bar with buttons for confirming and canceling the actions at the bottom of the screen.
The user can tap & hold the target, and drag it to a different position on the screen.
When released, the item is dropped at that particular position. The user can tap OK or Cancel to complete the action.
Use whenYour app can use drag & drop for sorting when the order of a list is important and should be customizable. Provide a clear visual target for this gesture. The target is usually located on the right of a list item. Show the actual movement of the item to make clear to the user what is happening. If you want your items to be sorted automatically according to a certain sort-key (such as name or size), consider using a sort-key dialog to sort.
