Cannot start TTS (Text to Speech)

Ok basically I have everything set up and I have set up my onClick method many times, but this time it is set up in my main.xml file

    <Button 
    android:layout_alignParentRight="true"
    android:layout_height="40dip" 
    android:layout_width="80dip" 
    android:id="@+id/speak" 
    android:enabled="true"
    android:visible="true"
    android:text="Speak" > 

</Button>

obviously it has other things to define its layout but that is one of the xml layouts inside my button, and for some reason every time I click on the button, it just closes the entire application, Why is that? also If I set it up to add a onClickListener then the button just does nothing.

I would set up my onClick listener like this

    speak.setOnClickListener(this);
     public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.speak:
        doSpeak();
        break;
    }
}

and it still doesnt work.... So i just dont know what I am doing wrong

     package com.write.it;

    import android.app.Activity;
    import android.content.Intent;
    import android.media.MediaPlayer;
    import android.os.Bundle;
    import android.speech.tts.TextToSpeech;
    import android.speech.tts.TextToSpeech.OnInitListener;
    import android.util.Log;
    import android.view.View;
    import android.widget.Button;
    import android.widget.EditText;

    public class Speech extends Activity implements OnInitListener {
private EditText words = null;
private Button speakBtn = null;
private static final int REQ_TTS_STATUS_CHECK = 0;
private static final String TAG = "TTS Demo";
    private TextToSpeech mTts = null;
    private MediaPlayer player = null;

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

    words = (EditText)findViewById(R.id.wordsToSpeak);
    speakBtn = (Button)findViewById(R.id.speak);



    // Check to be sure that TTS exists and is okay to use
    Intent checkIntent = new Intent();
    checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
    startActivityForResult(checkIntent, REQ_TTS_STATUS_CHECK);
}

public void doButton(View view) {
    switch(view.getId()) {
    case R.id.speak:
        mTts.speak(words.getText().toString(), TextToSpeech.QUEUE_ADD, null);
        break;

        }
            }

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQ_TTS_STATUS_CHECK) {
        switch (resultCode) {
        case TextToSpeech.Engine.CHECK_VOICE_DATA_PASS:
            // TTS is up and running
            mTts = new TextToSpeech(this, this);
            Log.v(TAG, "Pico is installed okay");
            break;
        case TextToSpeech.Engine.CHECK_VOICE_DATA_BAD_DATA:
        case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_DATA:
        case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_VOLUME:
            // missing data, install it
            Log.v(TAG, "Need language stuff: " + resultCode);
            Intent installIntent = new Intent();
            installIntent.setAction(
                TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            startActivity(installIntent);
            break;
        case TextToSpeech.Engine.CHECK_VOICE_DATA_FAIL:
        default:
            Log.e(TAG, "Got a failure. TTS apparently not available");
        }
    }
    else {
        // Got something else
    }
}

public void onInit(int status) {
    // Now that the TTS engine is ready, we enable buttons
    if( status == TextToSpeech.SUCCESS) {
        speakBtn.setEnabled(true);
        }
}

@Override
public void onPause()
{
    super.onPause();
    // if we're losing focus, stop playing
    if(player != null) {
        player.stop();
    }
    // if we're losing focus, stop talking
    if( mTts != null)
        mTts.stop();
}

@Override
public void onDestroy()
{
    super.onDestroy();
    if(player != null) {
        player.release();
    }
    if( mTts != null) {
        mTts.shutdown();
    }
        }
    }

I mean am i not setting the volume or setting or telling it to speak?!?!?, am I not telling it to do something it is supposed to do?..... the volume on my phone is on and the media volume is up, I have an HTC evo 4g so it should work..... here Ill add another one with utterance and the onClick Method

There are many things mixed up in your code, especially the part where you check the engine with a StartActivityforResult().

Please see this example of a working TTS: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/TextToSpeechActivity.html

Also you did not assign any ID to the button (apparently?) Could it be, that another button is using the ID?

/edit: First of all, merge both Activities. If you call onCreate()again, it will override the previous one. Then add implements OnClickListener and replace 

speakBtn.setOnClickListener((OnClickListener) this);

with 

speakBtn.setOnClickListener(this);

Eclipse will tell you that you need to add an unimplemented method.

If the XML code you copied at the top of your question is all you have to declare that button, then it is missing the id you expect (R.id.speak) in the handler...

I would suggest you add some debug prints in the doButton function see if that gets called correctly before going any further in the text-to-speech and so on.
