我在这里设置了所有的文本到语音转换(或者我想是这样)，但是当我去按我的应用程序上的按钮时，它就关闭了，并且没有说出我键入的内容，(现在我想知道这是不是因为我没有设置OnClickListener事件。原因是因为我真的知道如何用TextToSpeach设置OnClickListener事件，所以如果这是我的应用程序不能说话的原因，那么有人可以把我引到这方面的教程，这方面会有帮助。如果这不是原因，那么有人能解释一下我做错了什么吗？

您可以在doSpeak()方法中编写TTS speak方法。您甚至不需要调用这个方法doSpeak()。那你怎么能说出来呢。

在speak按钮中设置一个监听器，并在该监听器中调用doSpeak()。如果它还是不说话，请告诉我。
