回答1:

dont panic dude 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 u code and hint i think it will help u to achieve whatever u want...:)

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);

                        }
                    }
}
