Can't add dispatchTouchEvent in Adapter.

[Achisyg]

Hello, I am trying to add in my Adapter the following code:

@Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        return ZoomHelper.Companion.getInstance().dispatchTouchEvent(ev,this) || super.dispatchTouchEvent(ev);
    }

But the problem is that it shows up this problem:

How can I solve the problem and also add @NonNull ViewHolder holder as it is in the onBindViewHolder of my adapter?
