我在做什么错TextToSpeech

Question

我有文字到语音全部在这里设置（或者我认为），但当我按下我的应用程序上的按钮它只是关闭，并没有说我输入什么，（现在我想知道是不是因为我没有设置OnClickListener事件，原因是我真的知道如何使用TextToSpeach设置OnClickListener事件，所以如果这是我的应用程序不说话的原因，那么可以有人指点我在这个领域，这将有助于教程。如果它不是原因，那么有人可以解释我做错了吗？

Answer 1

您在doSpeak（）方法中编写TTS说法。而且你甚至不称这种方法为doSpeak（）。那你如何期待说出来？

在发言按钮中设置一个监听器，并在监听器中调用doSpeak（）。如果它仍然不说话，让我知道。
