Android How Do I get TTS to read From a Pre-Populated TextView

Question

Hi I really need some help with getting Android TTS to read from a pre-populated textview when the user clicks a button

my layout file currently consists of 1x button 1x textview and 1x imageView

any references or Ideas will be of great help.

here's my code

public class Bulbasaur extends Activity{
ListView l;
ImageView img;
TextView tv1;
Button btn1;
MediaPlayer mp;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.bulbasaur);
    img = (ImageView)findViewById(R.id.imageView2);
    img.setImageResource(R.drawable.national001);
    tv1 = (TextView)findViewById(R.id.textView2);
    TextToSpeech tts = new TextToSpeech(this, this);
    tts.setLanguage(Locale.US);

    tv1.setText("Dex Entry 001:\n" +
                "Bulbasaur can be seen napping in bright sunlight.\n" +
                "There is a seed on its back.\n" +
                "By soaking up the sun's rays, \n" +
                "the seed grows progressively larger.");
    btn1 = (Button)findViewById(R.id.cryBtn);
    mp = MediaPlayer.create(this, R.raw.bulbasaur);
    btn1.setOnClickListener(new View.OnClickListener(){

        public void onClick(View v) {
            mp.start();
        }
    });

    getActionBar().setDisplayHomeAsUpEnabled(true);


}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            // API 5+ solution
            onBackPressed();
            return true;

        default:
            return super.onOptionsItemSelected(item);
    }
}
}

ok thanks for the help :) but now it is crashing with these errors

    btn1.setOnClickListener(new View.OnClickListener(){

    public void onClick(View v) {
         String speak_text = tv1.getText();
         tts.speak(speak_text , TextToSpeech.QUEUE_ADD, null);
    }
   });

thanks, but now TextToSpeech(this,this) is showing an error – Vynllazuril Aug 20 '15 at 05:42
you need to add a listener for texttospeech – arun Aug 20 '15 at 05:47
@Vynllazuril implement this android.speech.tts.TextToSpeech.OnInitListener – Sunil Sunny Aug 20 '15 at 05:48
the implementation removes the error but it still crashes – Vynllazuril Aug 20 '15 at 06:09
