Text to speech android code

Question

I would like to ask about the correction of my problem. I saw an article that teaches how to use text to speech android code but I followed the code and my AVD does not seems to respond. So I went for another code and type it in, the avd does not seems to respond too. Can someone help me to check the error?

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    inputText=(EditText)findViewById(R.id.editText1);
    tts=new TextToSpeech(getApplicationContext(),
    new TextToSpeech.OnInitListener(){
        @Override
        public void onInit(int status){
            if(status!=TextToSpeech.ERROR){
                tts.setLanguage(Locale.UK);}
            }
        });
    }

@Override
public void onPause(){
    if(tts!=null){
        tts.stop();
        tts.shutdown();
    }
    super.onPause();
}

@Override

    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void speakText(View view){
    String toSpeak=inputText.getText().toString();
    Toast.makeText(getApplicationContext(), toSpeak,Toast.LENGTH_SHORT).show();
    tts.speak(toSpeak,TextToSpeech.QUEUE_FLUSH,null);
}


@Override

    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.

    }
    return super.onOptionsItemSelected(item);

Answer 1

There are few mistakes that I found :-

1. you do not need to implement onInitListener and override method onInit() because you are using it once and already overriding in OnCreate() method.

2. after onInit() in OnCreate() u need to call speakText() method.

speakText(inputText)

Answer 2

First mistake is that you haven't initialised your button in the onCreate,nor have you given an OnClickListener to it. Another problem here is with your onInit. When you're overriding it,try working around like this:

@Override
    public void onInit(int status) {

        if (status == TextToSpeech.SUCCESS) {

            int result = tts.setLanguage(Locale.UK);

            if (result == TextToSpeech.LANG_MISSING_DATA
                    || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                Log.e("TTS", "This Language is not supported");
            } else {
                button1.setEnabled(true);
                speakText();
            }

        } else {
            Log.e("TTS", "Initilization Failed!");
        }
    }

and the entire code would look something like this:

public class MainActivity extends Activity implements
        TextToSpeech.OnInitListener {

    private TextToSpeech tts;
    private Button speakButton;
    private EditText inputText;

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

        inputText = (EditText) findViewById(R.id.editText1);
        tts = new TextToSpeech(this, this);

        speakButton = (Button) findViewById(R.id.button1);
        // button on click event
        speakButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                speakOut();
            }

        });
    }

    @Override
    public void onDestroy() {
        // Don't forget to shutdown tts!
        if (tts != null) {
            tts.stop();
            tts.shutdown();
        }
        super.onDestroy();
    }

    @Override
    public void onInit(int status) {

        if (status == TextToSpeech.SUCCESS) {

            int result = tts.setLanguage(Locale.US);

            if (result == TextToSpeech.LANG_MISSING_DATA
                    || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                Log.e("TTS", "This Language is not supported");
            } else {
                speakButton.setEnabled(true);
                speakText();
            }

        } else {
            Log.e("TTS", "Initilization Failed!");
        }

    }

    private void speakText() {

        String toSpeak = inputText.getText().toString();

        tts.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
    }
}
