    import java.util.ArrayList;
    
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.speech.RecognizerIntent;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.ArrayAdapter;
    import android.widget.Button;
    import android.widget.ListView;
    
    public class MainActivity extends Activity {
    
        Button speak;
        ListView options;
        ArrayList<String> results;
    
        @Override
        protected void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            //doctory endsl...
            speak = (Button) findViewById(R.id.bSpeak);
            options = (ListView) findViewById(R.id.lvOptions);
    
            speak.setOnClickListener(new OnClickListener() 
            {
    
                @Override
                public void onClick(View v) 
                {
                    // This are the intents needed to start the Voice recognizer
                    Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
                   // i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                         //   RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
                    i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
                    i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 15); // number of maximum results..
                    i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say something");
    
                    startActivityForResult(i, 1010);
                }
            });
    
            // retrieves data from the previous state. This is incase the phones
            // orientation changes
            if (savedInstanceState != null) {
                results = savedInstanceState.getStringArrayList("results");
    
    
                if (results != null) {
                    options.setAdapter(new ArrayAdapter<String>(this,
                            android.R.layout.simple_list_item_1, results));
                }
            }
        }
    
        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            // TODO Auto-generated method stub
            // retrieves data from the VoiceRecognizer
            if (requestCode == 1010 && resultCode == RESULT_OK) {
                results = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
    
                if (results.contains("close"))
                {
                    finish();
                }//extra testing...
                options.setAdapter(new ArrayAdapter<String>(this,
                        android.R.layout.simple_list_item_1, (results));
            }
    
            super.onActivityResult(requestCode, resultCode, data);
        }
    
        @Override
        protected void onSaveInstanceState(Bundle outState) {
            // This should save all the data so that when the phone changes
            // orientation the data is saved
            super.onSaveInstanceState(outState);
    
            outState.putStringArrayList("results", results);
        } 
    
    }
    

    and xml is...

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
    
    <ListView
        android:id="@+id/lvOptions"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/button1" >
    </ListView>
    
    <Button
        android:id="@+id/bSpeak"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:text="Speak" />
