How to Catch Drop Event?

How do I catch the drop event?

[lkorth]

If you take a look at DragDropGrid at line 200, this is where the touch up and reordering is handled if something was dragged.

I modified ExamplePagedDragDropGridAdapter and added a method; isOrdered(), to check the list is ordered or not, for a special purpose.

public boolean isOrdered(){
    List<Item> items = pages.get(0).getItems();
    Long previousIndex = items.get(0).getId();
    for (int i = 1; i < items.size(); i++) {
        Long currentIndex = items.get(i).getId();
        if(currentIndex > previousIndex){
            previousIndex = currentIndex;
            continue;
        }
        else{
            return false;
        }
    }
    return true;
}

I need to catch somehow the drop event so later I can check if the list is ordered or not.

So from my Activity how can I catch the drop event? (Without modifying core source codes for DragDropGrid class)

Any time there is a drop that causes a reorder, swapItems() will be called.

I understood. But what about a listener? Are there any listener exists on DragDropGrid or adapter or items that I can listen it to catch drop events to call my method in adapter?

Thanks

Use swapItems() or modify DragDropGrid

[mrKlar]

You could create your own listener and use it in the adapter when swapItems is called.
