在Android中使用TextToSpeech需要以下步骤:
private TextToSpeech textToSpeech;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = textToSpeech.setLanguage(Locale.US); // 设置语言为英语
if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Language not supported");
}
} else {
Log.e("TTS", "Initialization failed");
}
}
});
}
textToSpeech.speak("Hello, World!", TextToSpeech.QUEUE_FLUSH, null);
注意,在使用完TextToSpeech后要记得在Activity或Fragment的onDestroy方法中释放TextToSpeech资源:
@Override
protected void onDestroy() {
if (textToSpeech != null) {
textToSpeech.stop();
textToSpeech.shutdown();
}
super.onDestroy();
}
这样就可以在Android中使用TextToSpeech进行文本转语音了。
