我在TextToSpeech上做错了什么

标签: android

我在这里设置了文字到语音(或者我认为)但是当我按下我的应用程序上的按钮时它就会关闭并且不会说出我输入的内容,(现在我想知道这是否是因为我没有设置OnClickListener事件。原因是因为我真的知道如何使用TextToSpeach设置OnClickListener事件,所以如果这就是为什么我的应用程序不说话,那么有人可以指导我这个教程有帮助的地区。如果不是原因,那么有人可以解释我做错了吗?

您在doSpeak()方法中编写TTS speak方法。而且你甚至没有调用这个方法doSpeak()。那你怎么期望说出来呢。

在侦听按钮中设置侦听器并在侦听器中调用doSpeak()。如果它仍然不说话,请告诉我。
