How to unfold the selected cell and fold others

[rmoustafa]

Is there a way/method to unfold only the selected cell and fold the others ?

[vikaskumark]

cell.setOnClickListener(new View.OnClickListener() {
@OverRide
public void onClick(View v) {
finalCell.toggle(false);
if (unfoldedIndexes.contains(lastItemPosition)) {
Log.v("LastItem", "LastItem" + lastItemPosition);
unfoldedIndexes.remove(lastItemPosition);
finalCell.fold(true);
notifyDataSetChanged();
}
lastItemPosition = position;
// register in adapter that state for selected cell is toggled
registerToggle(position);
}
});

cell is folding cell,lastItemPosition is previous clicked position

[Testator]

is registerToggle(position); the same as notifyItemChanged(position);

if not what is it?

thnx in advance
