I am retrieving values from server for autocompletetextview, I am getting the list of user names along with their user ids, now what I want is when i select any username from list I want to get user id of that username.
Please have look at my code:
SearchFriendsAdapter.java
public class SearchFriendsAdapter extends ArrayAdapter<String> {
private ArrayList<SearchFriends> items;
public static SearchFriends searchFriends;
public static ArrayList<String> friends_id;
boolean iNetAvailable;
Context context = getContext();
public SearchFriendsAdapter(Activity context, String nameFilter) {
super(context, R.layout.row_search_friend);
items = new ArrayList<SearchFriends>();
}
@Override
public int getCount() {
return items.size();
}
@Override
public String getItem(int index) {
return items.get(index).getFriend_name();
}
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.row_search_friend, null);
}
searchFriends = items.get(position);
if (searchFriends != null) {
TextView tv_friend_name = (TextView) v.findViewById(R.id.search_friend_txt_friend_name);
TextView tv_friend_email = (TextView) v.findViewById(R.id.search_friend_txt_friend_email);
SimpleDraweeView iv_friend_pic = (SimpleDraweeView)v.findViewById(R.id.search_friend_img_friend_pic);
tv_friend_name.setText(searchFriends.getFriend_name());
tv_friend_email.setText(searchFriends.getFriend_email_id());
iv_friend_pic.setImageURI(Uri.parse(searchFriends.getFriend_profile_pic()));
}
return v;
}
@Override
public Filter getFilter() {
Filter myFilter = new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults filterResults = new FilterResults();
iNetAvailable = Utility.isNetworkAvaliable(context);
SearchFriendsAsyncTask sf = new SearchFriendsAsyncTask();
if (constraint != null) {
List<SearchFriends> new_suggestions = sf.getParseJsonWCF(context, constraint.toString());
items.clear();
items.addAll(new_suggestions);
filterResults.values = items;
filterResults.count = items.size();
}
return filterResults;
}
@Override
protected void publishResults(CharSequence contraint,
FilterResults results) {
if (results != null && results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
};
return myFilter;
}
}
SearchFriendsAsyncTask.java
public class SearchFriendsAsyncTask {

nameValuePairs
.add(new BasicNameValuePair("name", sName));
String response = Utility.postRequest(webUrl, nameValuePairs);
JSONObject jObject = new JSONObject(response);
Log.v("SEARCH FRIENDS RESPONSE : ", jObject.toString());
searchFriendsModel = (SearchFriendsModel) new Gson().fromJson(
jObject.toString(), SearchFriendsModel.class);
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return searchFriendsModel.getFriends();
}
}

Here i am setting the adapter
et_search.setAdapter(new SearchFriendsAdapter(this, et_search.getText().toString()));
et_search.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
SearchFriendsAdapter adapter = ((SearchFriendsAdapter)
et_search.getAdapter());
String friend_id = ((SearchFriends)adapter
.getItem(position)).getFriend_user_id();
}
});
while I am trying to get user_id as above it gives me error "Cannot cast from String to SearchFriends"
Please help me to achieve what I want. Thanks in advance.
