Java OuttenceProgressListener不总是在文本到语音中调用？

我的代码：

import java.math.BigInteger;
import java.security.SecureRandom;
import java.util.HashMap;
import java.util.Locale;

import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Activity;
import android.os.Build;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.speech.tts.UtteranceProgressListener;
import android.widget.Toast;

@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1)
@SuppressLint("NewApi")
public class MainActivity extends Activity {
    public TextToSpeech tts;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        tts = new TextToSpeech(this, new ttsInitListener());
    }
    @SuppressLint("TrulyRandom") class ttsInitListener implements OnInitListener {

        @SuppressWarnings("deprecation")
        @Override
        public void onInit(int status) {

            if (status == TextToSpeech.SUCCESS) {
                tts.setLanguage(Locale.getDefault());
                if (!tts.isSpeaking()) {
                    SecureRandom random = new SecureRandom();
                    String aa= new BigInteger(130, random).toString(32);
                    HashMap<String, String> map = new HashMap<String, String>();
                    map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, aa);
                    tts.speak("Hello Hello HEllo HEllo HEllo",
                            TextToSpeech.QUEUE_FLUSH, map);
                    tts.setOnUtteranceProgressListener(new ttsUtteranceListener());
                }

            } else {
                tts = null;
                Toast.makeText(getApplicationContext(),
                        "Failed to initialize TTS engine.", Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }

    class ttsUtteranceListener extends UtteranceProgressListener {

        @Override
        public void onDone(String utteranceId) {

            Toast.makeText(getApplicationContext(), "onDone", Toast.LENGTH_LONG).show();

        }

        @Override
        public void onError(String utteranceId) {
            Toast.makeText(getApplicationContext(), "onError", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onStart(String utteranceId) {
            Toast.makeText(getApplicationContext(), "onStart", Toast.LENGTH_LONG).show();
        }
    }
}

Finish然后应该调用

onDone（stringouttanceid）

ttsunterancelistener类的方法。但是，

ttsunterancelistener

并不总是可以到达

为什么没有达到这个等级？

您正在使用这个：

String aa= new BigInteger(130, random).toString(32);
HashMap<String, String> map = new HashMap<String, String>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, aa);  //aa can be anything random, not necessary a word contained in your text

HashMap<String, String> map = new HashMap<String, String>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "Hello");
tts.speak("Hello Hello HEllo HEllo HEllo", TextToSpeech.QUEUE_FLUSH, map);
tts.setOnUtteranceProgressListener(new ttsUtteranceListener());

然后，当问候成功完成时，它将被触发

希望有帮助。

您调试了

String aa=new biginger（130，random）中创建的内容了吗？尝试使用静态参数一次。之前，我使用map.put（TextToSpeech.Engine.KEY_param_outrance_ID，“abc”）；尝试放置
map.put（TextToSpeech.Engine.KEY\u PARAM\u outrance\u ID，“hello”）因为您的文本不包含abc，但包含hello。因为话语进程侦听器用于侦听特定文本的话语进程。如果该文本被说出，它将被激发。SecureRandom=new SecureRandom（）；字符串aa=新的BigInteger（5，随机）.toString（32）；字符串abc=“abc”+aa；Toast.makeText（_mContext，“value:+abc，Toast.LENGTH_LONG）.show（）；HashMap=newHashMap（）；map.put（TextToSpeech.Engine.KEY_PARAM_speak_ID，abc）；
HashMap<String, String> map = new HashMap<String, String>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "Hello");
tts.speak("Hello Hello HEllo HEllo HEllo", TextToSpeech.QUEUE_FLUSH, map);
tts.setOnUtteranceProgressListener(new ttsUtteranceListener());
