Answer 1

Your Ctx is null. You should give a valid Context object, either from an Activity or a View.

You can try this:

@Override
public void onBindViewHolder(Adater_pemilik.ViewHolder holder, final int position) {

   ......
   Glide.with(holder.fot.getContext())   // Change this line
           .load(hah)
           .into(holder.fot);

   .....

}
