Android 自动朗读textView中的内容

最近自己写了一个抽签的小程序，想着抽签之后会语音播报出来，于是就想到了简单的TextToSpeech。

首先实例化TextToSpeech

TextToSpeech  texttospeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
            
            @Override
            public void onInit(int status) {
                // TODO Auto-generated method stub
                if (status == texttospeech.SUCCESS) {
                    int result = texttospeech.setLanguage(Locale.CHINA);
                    if (result != TextToSpeech.LANG_COUNT
