问题 I use - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{ } method for dragging and dropping rows within and across sections. Can I perform drags with sections as well? 回答1: It's probably conceptually (as well as technically) simpler to step back a level to a table view where each row corresponds to the sections of the table you want to re-order. Maybe you could invoke this with a "re-order sections"

问题 I have a ListFragment that has a custom adapter so that I could have a text view and an image view on each row. When dragging this row to my canvas (a separate fragment), it shows the whole row as the drag shadow (default behavior). I want to drag only the icon/image to the canvas.

问题 I have a listview where I made it possible to rearrange the elements via drag-and-drop and it works fine, however I want to replace the two default icons with my own custom ones. I have tried with i.e. setCursor(Cursor.HAND) setCursor(new ImageCursor(image)) on both the ListCell itself or its parents but nothing gets reflected during the drag, only after, which is not what I want.
