feedback

public int feedback

A bitwise OR'ing of the drag under effect feedback to be displayed to the user (e.g. DND.FEEDBACK_SELECT | DND.FEEDBACK_SCROLL | DND.FEEDBACK_EXPAND).

A value of DND.FEEDBACK_NONE indicates that no drag under effect will be displayed.

Feedback effects will only be applied if they are applicable.

The default value is DND.FEEDBACK_SELECT.
