Android Studio: 10秒后如何启动TexttoSpeech？

Handler handler = new Handler();

handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        // 在这里编写启动TexttoSpeech的代码
    }
}, 10000); // 10秒后启动

handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        TextToSpeech tts = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    // TexttoSpeech初始化成功
                    int result = tts.setLanguage(Locale.US);
                    if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                        // 不支持或缺少语言数据
                        Log.e("TTS", "Language not supported");
                    } else {
                        // 启动TexttoSpeech成功，可以开始使用
                        tts.speak("Hello, World!", TextToSpeech.QUEUE_FLUSH, null);
                    }
                } else {
                    // TexttoSpeech初始化失败
                    Log.e("TTS", "Initialization failed");
                }
            }
        });
    }
}, 10000); // 10秒后启动
