Unfold cell programmatically

[basmasrour]

How to unfold or fold cell in specific index of list view programmatically without click on it?
when I called cell.unfold(true) returns NullPointerException:
Attempt to write to field 'int android.view.ViewGroup$LayoutParams.height' on a null object reference

when use cell.toggle(false);
registerToggle(position);
returns FATAL EXCEPTION: main
Process: PID: 30807
java.lang.IllegalArgumentException: width and height must be > 0
