文本到语音转换在Android Studio中无法正常工作

我最近在android studio中创建了一个简单的项目，使用语音识别和文本到语音，但问题是文本到语音在第一次启动应用程序时不能说出给定的行，但在此事件后它工作得非常正常。比如当我在下面的代码中启动应用程序时，我添加了欢迎用户的行，但tts没有。t speak，然后当我按下识别按钮，应用程序识别句子，也正确地说。为什么会这样呢？这似乎很奇怪。我提供了下面的代码，请检查它，并告诉我，如果我犯了一些错误，尽快。
这是我的Java代码：

它以前不起作用的原因和DB377说的一样，那是因为tts的初始化是异步的，只有当进程完成时才调用onInit，执行不一定是逐行进行的。
您可以按如下方式更改代码：

// THIS RUNS FIRST
textToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {

        // THIS RUNS THIRD!
        @Override
        public void onInit(int i) {
            if (i == TextToSpeech.SUCCESS) {

                textToSpeech.setLanguage(Locale.ENGLISH);

                // NEW LOCATION
                textToSpeech.speak("Hi you succesfully ran me.", TextToSpeech.QUEUE_FLUSH, null, null);

            }

        }
    });

    // OLD LOCATION (THIS RUNS SECOND)

您可以尝试创建一个应用程序类，并在其中初始化您的textToSpeech引擎，以便它在应用程序启动时开始初始化。

public class MyApp extends Application {
    private static MyApp instance = null;
    private TextToSpeech t1;

    public static MyApp getInstance() {
        return instance;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;

        t1 = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int i) {
                if (i == TextToSpeech.SUCCESS) {
                    
                }
            }
        });
    }

    public TextToSpeech getT1() {
        return t1;
    }
}

然后在你的活动中使用它。

//这对我很有效：
//在此处将文本转换为语音

// Create a Handler object to run some code after a delay
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        // Your code to run after a delay. in my case in another handler
