如何在android studio avd中激活文本到语音转换

import android.speech.tts.TextToSpeech;
import android.speech.tts.UtteranceProgressListener;

// 创建TextToSpeech对象
TextToSpeech textToSpeech = new TextToSpeech(context, new TextToSpeech.OnInitListener() {
    @Override
    public void onInit(int status) {
        if (status == TextToSpeech.SUCCESS) {
            // 设置语言
            int result = textToSpeech.setLanguage(Locale.US);
            if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                // 当语言不可用时的处理逻辑
            } else {
                // 设置激活监听器
                textToSpeech.setOnUtteranceProgressListener(new UtteranceProgressListener() {
                    @Override
                    public void onStart(String utteranceId) {
                        // 播放开始时的处理逻辑
                    }

                    @Override
                    public void onDone(String utteranceId) {
                        // 播放完成时的处理逻辑
                    }

                    @Override
                    public void onError(String utteranceId) {
                        // 播放错误时的处理逻辑
                    }
                });
            }
        } else {
            // 初始化失败时的处理逻辑
        }
    }
});

// 将文本转换为语音并播放
String text = "要转换为语音的文本";
textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, "1");
