Retrieving an element from array list in Android?

Question

I am trying to implement voice recognition code in Android. How do I get an element at a particular position from array list in Android? I tried converting arraylist to array and retriving. Still the code is not working.

package com.espeaker;


    public class EspeakerActivity extends Activity {

                    private static final int REQUEST_CODE = 1234;
            private ListView wordsList;


            /** Called when the activity is first created. */
            @Override
            public void onCreate(Bundle savedInstanceState) {
                  super.onCreate(savedInstanceState);
                  setContentView(R.layout.main);


                  Button speakButton = (Button) findViewById(R.id.speakButton);

                  wordsList = (ListView) findViewById(R.id.list);

                  // Disable button if no recognition service is present
                  PackageManager pm = getPackageManager();
                  List<ResolveInfo> activities = pm.queryIntentActivities(
                          new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
                  if (activities.size() == 0)
                  {
                      speakButton.setEnabled(false);
                      speakButton.setText("Recognizer not present");
                  }
            }

    /**
     * Handle the action of the button being clicked
     */
    public void speakButtonClicked(View v)
    {
        startVoiceRecognitionActivity();
    }

    /**
     * Fire an intent to start the voice recognition activity.
     */
    private void startVoiceRecognitionActivity()
    {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Voice recognition Demo...");
        startActivityForResult(intent, REQUEST_CODE);
    }

    /**
     * Handle the results from the voice recognition activity.
     */
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        if (requestCode == REQUEST_CODE && resultCode == RESULT_OK)
        {
            // Populate the wordsList with the String values the recognition engine thought it heard
            ArrayList<String> matches = data.getStringArrayListExtra(
                    RecognizerIntent.EXTRA_RESULTS);
            wordsList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
                    matches));
            String[] array=matches.toArray(new String[matches.size()]);
           // ArrayList<String> places = new ArrayList<String>(
                //    Arrays.asList("black", "blue", "red"));
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item,matches);
              final AutoCompleteTextView input_text = (AutoCompleteTextView) findViewById(R.id.auto);
              Button button1 = (Button) findViewById(R.id.button1);
                     input_text.setAdapter(adapter);
            button1.setText(" "+array[0]);

           // button1.setText(""+matches);
             }
        super.onActivityResult(requestCode, resultCode, data);
    }
    }
