Drag and drop feature on Material Design specs are great UX guide to provide a delightful motion on dragging and dropping gestures.

Java Usage

 MaterialDnd dnd = new MaterialDnd();
 // Set the draggable object
 dnd.setDraggable(widget);

 // Set the ignored widget when dragging the element
 dnd.setIgnoreFrom(toolbar);
