DragSortAdapter
DragSortAdapter copied to clipboard
I have a similar issue with #11,"use the DragSortAdapter with List<String>"
I change Integer to String with hashCode()
and it'll crash if I drag the item.It's like #11 .Could you show me a right example how to use it ? Thank you very much!
Hey, I think i have a clean solution for this problem. For storing your objects use a HashMap<Integer, <YourObject> objects; For storing the keys use a ListView<Integer> keys;
Get Object from position:
YourObject yourObject = yourObjects.get(keys.get(position));
Add object:
int key = phases.hashCode();
keys.add(key);
phases.put(key, phase);
notifyDataSetChanged();
Remove object:
int key = keys.get(phase.hashCode());
keys.remove(key);
phases.remove(key);
otifyDataSetChanged();
Override methods:
@Override
public int getItemCount() {
return keys.size();
}
@Override
public long getItemId(int position) {
return keys.get(position);
}
@Override
public int getPositionForId(long id) {
return keys.indexOf((int)id);
}
@Override
public boolean move(int fromPosition, int toPosition) {
keys.add(toPosition, keys.remove(fromPosition));
return false;
}
