		this.activity = activity;
		textToSpeech = new TextToSpeech(activity,
				new TextToSpeech.OnInitListener() {

					@Override
					public void onInit(int status) {
						if (status == TextToSpeech.SUCCESS) {
							int result = textToSpeech.setLanguage(Locale.US);
							if (result == TextToSpeech.LANG_MISSING_DATA
									|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
								Log.e("MESSAGE", "不支持的语言");
							}
