how to get id of selected item in autocompletetextview in android

Change this in adapter

@Override
public SearchFriends getItem(int index) {

    return items.get(index);

}


et_search.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View arg1, int position,
                long arg3) {
            // TODO Auto-generated method stub
            SearchFriends freindPOJO= adapter
                    .getItem(position);
String friends_id = freindPOJO.getFriend_user_id()

        }
    });

Adapter you are using for et_search using ArrayList<SearchFriends>

and you are trying to get friend_id which is string or int and you are casting it to SearchFriends which is not possible.

if you want SearchFriends object then use like this

SearchFriends object = (SearchFriends)adapter.getItem(position);

Sorry i have not check you adapter

here is the mistake you are returning string here so you cannot get SearchFriends

@Override
public String getItem(int index) {

    return items.get(index).getFriend_name();

}

So i will say do this and you are good to go.

@Override
public SearchFriends getItem(int index) {
        return items.get(index);    
}
