    Filter myFilter = new Filter() {

        @Override
        protected FilterResults performFiltering(CharSequence constraint) {
            FilterResults filterResults = new FilterResults();
            JsonParse jp=new JsonParse();
            if (constraint != null) {
                // A class that queries a web API, parses the data and
                // returns an ArrayList<GoEuroGetSet>
                new_suggestions =jp.getParseJsonWCF(constraint.toString());
                suggestions.clear();
                for (int i=0;i<new_suggestions.size();i++) {
                    suggestions.add(new_suggestions.get(i).getName());

                }

                // Now assign the values and count to the FilterResults
                // object
                filterResults.values = suggestions;
                filterResults.count = suggestions.size();
            }
            return filterResults;
        }

        @Override
        protected void publishResults(CharSequence contraint,
                FilterResults results) {
            if (results != null && results.count > 0) {
                notifyDataSetChanged();
            } else {

} response

{"results":[{"id":"1","name":"ab"},{"id":"2","name":"abc"},{"id":"3","name":"bc"},{"id":"4","name":"bcd"},{"id":"5","name":"cd"},{"id":"6","name":"cde"},{"id":"7","name":"ef"},{"id":"8","name":"efg"},{"id":"9","name":"hi"},{"id":"10","name":"hig"},{"id":"11","name":"jk"},{"id":"12","name":"jkl"},{"id":"13","name":"mn"},{"id":"14","name":"mno"},{"id":"15","name":"pq"},{"id":"16","name":"pqr"},{"id":"17","name":"st"},{"id":"18","name":"stu"},{"id":"19","name":"vw"},{"id":"20","name":"vwx"},{"id":"21","name":"yz"},{"id":"22","name":"yza"}]}

in that example they get name and id from server see here http://webheavens.com/suggestion.php?name= — Aditya Vyas-Lakhan, Sep 11 '15 at 09:14
see carefully the method signature: `onItemClick(AdapterView> parent, View view, int position, long id)` is there an `id`? — pskink, Sep 11 '15 at 09:20
@pskink id which i have in response..that i want when user click on item..see my edited answer..suppose if i click on "ab" i want to get id "1" — Aditya Vyas-Lakhan, Sep 11 '15 at 09:27
as i said use the last param `id`, why do you think it is passed to `onItemClick` method? BTW you dont need to write that long custom adapter, see: http://stackoverflow.com/a/19860624/2252830 — pskink, Sep 11 '15 at 09:30
@pskink then in my toast i am getting name..can you tell why? — Aditya Vyas-Lakhan, Sep 11 '15 at 09:32
@ρяσѕρєяK see edited question...i am getting null on click — Aditya Vyas-Lakhan, Sep 11 '15 at 12:06
@Lakhan: lots of changes required see my answer for help. let me know still facing any issue in posted issue — ρяσѕρєя K, Sep 11 '15 at 12:21

Put one method in adapter

public Int getItemId(int index) {
    return suggestions.get(index).getId();
}

Then access it in onItemClick. You will getId from there by adapter.getItemId(position);

How to get id of autocompletetextview item?

new_suggestions contains all items which want to get on ListView item click. so declare it outside getFilter method for access from other class:

private List<String> suggestions;
private List<SuggestGetSet> new_suggestions ;
....

new_suggestions initilize it inside getFilter method:

...
new_suggestions =jp.getParseJsonWCF(constraint.toString());
suggestions.clear();
...

Now create a method inside SuggestionAdapter :

public List<SuggestGetSet>  getAllUpdatedSuggestion(){
  return this.new_suggestions;
}

and finally inside onItemClick call getAllUpdatedSuggestion method:

final SuggestionAdapter adapter=new SuggestionAdapter(this,
                                acTextView.getText().toString())
acTextView.setAdapter(adapter);

and in onItemClick method:

   @Override
    public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
        SuggestGetSet  selectedSuggestGetSet = 
                     adapter.getAllUpdatedSuggestion().get(position);
    }

selectedSuggestGetSet will contains selected item name and id

@pskink your code work well..but my issue was to get id on click of item..but i dint get it from your code too..so again i work on this complex code – Aditya Vyas-Lakhan Sep 11 '15 at 12:49
@Lakhan i give up, i already said three times: use the last parameter of onItemClick: long id – pskink Sep 11 '15 at 12:50
@ρяσѕρєяK yes i tried but in my toast it is not showing id and name – Aditya Vyas-Lakhan Sep 11 '15 at 13:01
@ρяσѕρєяK see question – Aditya Vyas-Lakhan Sep 11 '15 at 13:10
@Lakhan: use `Toast.makeText(getApplicationContext(), selectedSuggestGetSet.getName()+" ID "+selectedSuggestGetSet. getId(), Toast.LENGTH_SHORT).show();` – ρяσѕρєя K Sep 11 '15 at 13:24

Change your suggestions list to public :

public List<String> suggestions;

And then get the desired id in your itemClick method :

 @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

            your id = YourAdapter.suggestions[position].id;

        }

check this

List<SuggestGetSet> new_suggestions = jp.getParseJsonWCF(constraint.toString());

and make one with private List<SuggestGetSet> new_suggestions; in your adapter
