android - How to get string from selected item of SimpleCursorAdapter?

Question

I'm using an AutoCompleteTextView to suggest user some words from my sqlite db as they type the input string to search.

I try to make the suggestion look friendly by using simple_list_item_2, here's my code:

package com.suit.kamus;

import android.app.Activity;
import android.database.Cursor;
import android.database.MatrixCursor;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.Button;
import android.widget.SimpleCursorAdapter;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.AdapterView.OnItemClickListener;

public class SuitAuto extends Activity implements TextWatcher{
AutoCompleteTextView auto; TextView result;
Button search; Button add; Spinner chooser;
String input; static String selection; String main;
String[] options = {"en to ina", "ina to en"};
SimpleCursorAdapter simple;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    auto = (AutoCompleteTextView)findViewById(R.id.auto);
    auto.addTextChangedListener(this);

    result = (TextView)findViewById(R.id.result);

    chooser = (Spinner)findViewById(R.id.chooser);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, options);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    chooser.setAdapter(adapter);

    KamusDbAdapter dbHelper = new KamusDbAdapter(getApplicationContext());
    dbHelper.open();
    String status = dbHelper.getstatedb();
    selection = status;
    dbHelper.close();

    if (selection.equalsIgnoreCase("en")){
        chooser.setSelection(0);
    } else {chooser.setSelection(1);}

    Log.d("statelang", selection);

    add = (Button)findViewById(R.id.add);
    add.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            startAdding(main);
        }

    });

    chooser.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub
            if (chooser.getSelectedItemId() == 0){
                selection = "en";
                select();
                updateDb();
            }else{
                selection = "ina";
                select();
                updateDb();
            }
        }

        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

    auto.setOnItemClickListener(new OnItemClickListener(){
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            // TODO Auto-generated method stub

            main = auto.getText().toString();
            //Log.v("CURSOR",finish);
            result.setText("");
            auto.setText("");
        }
    });


}

public void startAdding(String dWord) {
    // TODO Auto-generated method stub
    KamusDbAdapter adding = new KamusDbAdapter(getApplicationContext());
    adding.open();
    adding.Favorite(dWord);
    adding.close();
}

protected void updateDb() {
    // TODO Auto-generated method stub
    KamusDbAdapter save = new KamusDbAdapter(getApplicationContext());
    save.open();
    save.updatestatedb(selection);
    save.close();
}


public static String select() {
    // TODO Auto-generated method stub
    Log.v("STRING",selection);
    return selection;
}

@Override
public void afterTextChanged(Editable arg0) {
    // TODO Auto-generated method stub

}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
        int arg3) {
    // TODO Auto-generated method stub

}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
    // TODO Auto-generated method stub
    input = auto.getText().toString();

    KamusDbAdapter x = new KamusDbAdapter(getApplicationContext());
    x.open();
    Cursor cur = x.getCall(input, selection);
    //getCall is in KamusDbAdapter class, it used to return result cursor from sqlite db
    //i use rawQuery "SELECT * FROM en_to_ina WHERE word LIKE 'input%'"
    x.close();

    String[] displayFields = new String[] {"word", "meaning"};

    int[] displayViews = new int[] { android.R.id.text1,android.R.id.text2 };

    simple = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_2, cur,displayFields, displayViews);

    auto.setAdapter(simple); 

}
}

I got a problem with retrieving the string from clicked item. It is in:

auto.setOnItemClickListener(new OnItemClickListener(){
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            // TODO Auto-generated method stub

            main = auto.getText().toString();
            //Log.v("CURSOR",finish);
            result.setText("");
            auto.setText("");
        }
    });

I need both strings from word and meaning fields. Any response would be great...

You need to use http://developer.android.com/reference/android/widget/CursorAdapter.html#getItem(int).

Cursor cursor = (Cursor) simple.getItem(position);
// retrieve the data from the cursor
