TextToSpeech我在做什么错

Question

I have text to speech all set up here (or so I think) but when I go to press the button on my application it just closes and does not speak what I type in, (Now I was wondering if this is because I have not set up an OnClickListener event. The reason why is because I really do know how to set up the OnClickListener event with teh TextToSpeach, So if that is the reason why My app isnt speaking then can someone direct me to a tutorial in this area that will help. If its not the reason why, then can someone explain what I am doing wrong?

Answer 1

You write TTS speak method in doSpeak() method. And you don't even call this method doSpeak(). Then how do you expect to speak it.

Set a listener in speak button and call doSpeak() in the listener. If still it don't speak, let me know.
