How to use Picasso in an Adapter without using context in Fragment

Question

When I try to use context in my fragment I get the error:

constructor Adapter in class Adapter cannot be applied to given types; required:Context,List<ListItem>,OnItemClickListener

I have declared my context in my adapter as follows:

 private Context mContext;

then i initialized the context:

 public MyAdapter(Context context,List<ListItem> listItems, OnItemClickListener callback) {
    this.listItems = listItems;
    this.callback = callback;
    this.mContext = context;

}

And used mContext to get my imageurl in the onBindViewHolder using picasso

 @Override
        public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
            ListItem listItem = listItems.get(position);

     Picasso.with(mContext).load(listItem.getImageurl()).into(holder.imageUrl;

        }

But now I can't seem to get around using this context in my Fragment.

This is what I've tried: In my Fragment:

//an error occurs

 adapter = new MyAdapter(this,listItems);

so I tried this:

//still get an error

  adapter = new MyAdapter(getContext(),this);

I also tried getActivity but still get an error

adapter = new MyAdapter(getActivity());

where am I going wrong? All I am really trying to do is display the image in my listfragment but I don't know how to use Picasso with using context, and MyAdapter does not require context to function properly. I've been using it without declaring context and the data displays properly. Onclick is also working and displaying strings from firebase, but now I need to display images from Firebase using Picasso into my listfragment. Everything else works fine except this line of code in my Fragment:

adapter = new MyAdapter(getActivity());

You try Get context from any View object in Holder. Example:

mContext = holder.imageView.getContext()
