Don't panic, just match both list and take one temp arraylist and when any name match then add in that temp arraylist and then show that list view according to that temp arraylist. :)

Here I give you code and hint:

ArrayList<String> matchname = new ArrayList<String>();
                for(int k =0;k<name1;k++)
                {
                    for(int l =0;l<name2.size();l++)
                    {
                        String keyname = name1[k];

                        if((keyname.trim().equals(name2[l].trim())))
                        {
                            matchname.add(keyname);

                        }
                    }
}
