Listmap scroll to specified item

Question

How do I do it so that if textviewM is clicked, the listview1 will scroll to the position of the item starting with the letter M of listmap.

textviewM on click

My code

textviewM.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View _view) {
        
    }
});

Thank you to everyone who wants to help
