java code for speech to text

[Glen Hynes]

hello all. the code below is used to convert speech to text on an android app. This code works when the speech button is pressed and whatever you say is transferred into text.
When the speech function closes, the the text is showing.
If you hit the speech button again, the previous text is cleared and the new text shows on the page.
Can anyone help me edit the code so that the previous texts remain on the page?

package net.viralpatel.android.speechtotextdemo;

import java.util.ArrayList;

import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.Menu;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

	protected static final int RESULT_SPEECH = 1;

	private ImageButton btnSpeak;
	private TextView txtText;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

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

		btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);

		btnSpeak.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View v) {

				Intent intent = new Intent(
						RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

				intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");

				try {
					startActivityForResult(intent, RESULT_SPEECH);
					txtText.setText("");
				} catch (ActivityNotFoundException a) {
					Toast t = Toast.makeText(getApplicationContext(),
							"Ops! Your device doesn't support Speech to Text",
							Toast.LENGTH_SHORT);
					t.show();
				}
			}
		});

	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
	}

	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		super.onActivityResult(requestCode, resultCode, data);

		switch (requestCode) {
		case RESULT_SPEECH: {
			if (resultCode == RESULT_OK && null != data) {

				ArrayList<String> text = data
						.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

				txtText.setText(text.get(0));
			}
			break;
		}

		}
	}
}

The general strategy would be to get the previous text, append the new String to the old text, then add the text back to the TextView. It may be a little more complicated because you probably want to add a line break, and maybe other conditions (like a fixed number of lines to display, scrolling, or something.

An alternative to the TextView which may better match your goals might be to use a ListView. The ListView can be bound to an ArrayAdapter. Whenever you get a String you would add it to the ArrayAdapter, which would cause the ListView to expand to accommodate the new text. It makes it easier to control the values which get displayed (the number of lines, formatting, etc...)
