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 one rror(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);
             }
         });

  }

}
