can you please tell me how to make custom filter in android using bas adapter ? I make a simple demo of auto complete. I take array of string in which there is 2250 entries with Name and code like that example "Alexandra Palace-(AAP)", first name is given and the it code inside the bracket.my issue is I need to filter this using code not by name .In other word if i type anything in input field it filter with starting characters of element mean name I need to filter with code which is inside the bracket.

Code:

package com.firstgroup.global;
public class GlobalList {

    public static String[] stationList={

};

}

when I type "lwy" it will not show "MNCRLWY-(LWY)", can you please tell how I will achieve this ?

here is my code..

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.select_station);

 autocompleteView = (AutoCompleteTextView) findViewById(R.id.item_autoComplete);

 STATION_LIST = new String[GlobalList.stationList.length
                                    + GlobalExtendStationList.stationList.length];
                            System.arraycopy(GlobalList.stationList, 0, STATION_LIST, 0,
                                    GlobalList.stationList.length);
                            System.arraycopy(GlobalExtendStationList.stationList, 0,
                                    STATION_LIST, GlobalList.stationList.length,
                                    GlobalExtendStationList.stationList.length);
                            autosuggestAdapter = new CustomAutocompletAdapter(this,STATION_LIST);
                            autocompleteView.setAdapter(autosuggestAdapter);

customAutosuggestAdapter:

public class CustomAutocompletAdapter extends BaseAdapter implements Filterable{

    String[] autolistArray;

            }

            final TextView stationNameAndCode = (TextView) v
                    .findViewById(R.id.item_selectStationName);



            final String stationNameAndCodeValue = autolistArray[position];


            stationNameAndCode.setText(stationNameAndCodeValue);

                Locale locale = Locale.getDefault();

                        .toString().toLowerCase(locale);
                if (constraint == null || constraint.length() == 0) {

                    // set the Original result to return

                } else {


                }
                return results;
            }

            @Override
            public CharSequence convertResultToString(Object resultValue) {
                // TODO Auto-generated method stub
                //convert object to string
                Log.d("-----------", "convertResultToString");
                return "";
            }
        };
        return myFilter;
    }

}

It is not showing no auto suggest. Could you please tell how I will achieve this? Mean filter functionality? I want to add filter method when I type in input field it filter from code not from name..
