android - 将文本转换为语音

Question

我正在使用以下代码。它工作正常，除了我有要转换为语音的文本列表的问题。但它只是将最后一行转换为演讲。这是我将数据放入 ListView 并尝试将其转换为语音的代码:

  public class TextSpeech extends ListActivity implements
  TextToSpeech.OnInitListener {
  /** Called when the activity is first created. */

 private TextToSpeech tts;

 private TextView txtText;
 private List<Message> mess;
 List<String> titless;

@SuppressLint("NewApi")
@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.speach);

 tts = new TextToSpeech(this, this);


 BaseFeedParser parser = new BaseFeedParser();
 mess = parser.parse();
 titless = new ArrayList<String>(mess.size());
    speakOut();
}

@SuppressLint("NewApi")
 @Override
 public void onDestroy() {
 // Don't forget to shutdown tts!
 if (tts != null) {
tts.stop();
tts.shutdown();
  }
super.onDestroy();
  }


@SuppressLint("NewApi")
@Override
public void onInit(int status) {

if (status == TextToSpeech.SUCCESS) {

int result = tts.setLanguage(Locale.US);

if (result == TextToSpeech.LANG_MISSING_DATA
        || result == TextToSpeech.LANG_NOT_SUPPORTED) {
    Log.e("TTS", "This Language is not supported");
} else {

    speakOut();
}

    } else {
Log.e("TTS", "Initilization Failed!");
    }

   }

   public void speakOut() {
     for (Message msg : mess){
 titless.add(msg.getTitle());
 tts.speak(msg.getTitle(), TextToSpeech.QUEUE_FLUSH, null);
         }
     ArrayAdapter<String> adapter = 
     new ArrayAdapter<String>(this, R.layout.row,titless);
     this.setListAdapter(adapter);
      }
     }

Answer 1

您使用过 TextToSpeech.QUEUE_FLUSH 只是将其更改为 TextToSpeech.QUEUE_ADD 。根据您的要求，您希望 TTS 逐条阅读。
