简单的文本语音朗读功能实现
实现这个功能主要用一个类，是TextToSpeech，废话不都少，直接上代码。总的来说效果一般，短语的停顿节奏不是很好。
界面很简单，一个Button ,一个EditView,就不贴代码了
public class ActivityResumptionArticle extends BaseActivity{
private TextToSpeech mSpeech = null; private Button btn = null;
private EditTextView ev = null;
protected void onCreate(Bundle arg0) { super.onCreate(arg0);
setContentView(R.layout.activity_resumption_article);
//测试朗读功能 btn = (Button) findViewById(R.id.but);
ev = (EditView)findViewById(R.id.ev); mSpeech = new TextToSpeech(this, new OnInitListener() { @Override public void onInit(int status) { if (status == TextToSpeech.SUCCESS) {
//下面这句代码是主要的，设置语言，如果是英文的话，就用Locale.ENGLISH int result = mSpeech.setLanguage(Locale.CHINA); if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) { Log.e("lanageTag", "not use"); } else { btn.setEnabled(true); mSpeech.speak("i love you", TextToSpeech.QUEUE_FLUSH, null); } }
} });
//进度监听器，有点粗糙，但够用了，记得在done后将mpeech shutdown mSpeech.setOnUtteranceProgressListener(new UtteranceProgressListener() { @Override public void onStart(String utteranceId) { } @Override public void onError(String utteranceId) { } @Override public void onDone(String utteranceId) { mSpeech.shutdown(); } }); btn.setOnClickListener(new OnClickListener() {
@Override public void onClick(View v) { // 开始朗读
mSpeech.speak(ev.getText().toString(), TextToSpeech.QUEUE_FLUSH, null); } });
}
}
