How about add your code, so we see where we can help. Instead of pasting for you a code in general. — Hasan Bou Taam, Apr 18 '20 at 13:17
It looks like you want us to write some code for you. While many users are willing to produce code for a coder in distress, they usually only help when the asker has already tried to solve the problem on their own. A good way to demonstrate this effort is to include the code you've written so far, example input (if any), the expected output/behavior, and the output you actually get ([logcat logs](//developer.android.com/studio/debug/am-logcat), [stack traces](//stackoverflow.com/a/23353174), etc.). The more detail you provide, the more answers you are likely to get. Check the [FAQ] and [ask]. — Ryan M, Apr 20 '20 at 02:55

Adapter class

    OnLongItemClickListener longClickListener;

    @Override
    public void onBindViewHolder(final DocumentViewHolder viewHolder, int position) {

        ...
        viewHolder.itemView.setLongClickable(true);
        ...
    }

    public void setLongClickListener(OnLongItemClickListener longClickListener) {
       this.longClickListener = longClickListener;
    }

OnLongItemClickListener

interface OnLongItemClickListener{
 void longClick(Item item)
}

After in your activity / fragment implements OnLongClickListener after call adapter.setLongClickListener (this) in the method that appears, call alertDialog, when you click the ok button, remove item from the list and call

adapter.notifydatasetchanged()

You can add below code in onBindViewHolder method..

 holder.itemView.setOnLongClickListener {
val builder = AlertDialog.Builder(this)
        builder.setTitle("Delete")
        builder.setMessage("Are you Sure To Delete?")

        builder.setPositiveButton(android.R.string.yes) { dialog, which ->
            Toast.makeText(applicationContext,
                    android.R.string.yes, Toast.LENGTH_SHORT).show()
        }

        builder.setNegativeButton(android.R.string.no) { dialog, which ->
            Toast.makeText(applicationContext,
                    android.R.string.no, Toast.LENGTH_SHORT).show()
        }

        builder.setNeutralButton("Maybe") { dialog, which ->
            Toast.makeText(applicationContext,
                    "Maybe", Toast.LENGTH_SHORT).show()
        }
        builder.show()
        false
        }
