Android的TTS onUtteranceCompleted回调是没有得到所谓的 [英] Android TTS onUtteranceCompleted callback isn't getting called

问题描述

我试图获取Android TTS API来读我的话语，然后调用onUtteranceCompleted（）监听器失败。我已经登记自己的TTS对象，并将其返回的成功，让我想不通，我为什么我的回调是没有得到所谓的生活。

我试图寻找帮助，但似乎其他人有困难这一点。我失去了一些东西简单？

感谢您的帮助，您可以提供。

解决方案

调用setOnUtteranceCompletedListener的TTS对象的OnInit函数中。

如果您想进行任何更改的onUtteranceCompleted函数的调用用户界面，添加code进行runOnUIThread方法中。

和千万要记得添加HashMap的参数值，同时调用说话（）函数

例如：

  TextToSpeech TTS =新TextToSpeech（背景下，新OnInitListener（）{

 @覆盖
 公共无效的OnInit（INT状态）{

    mTts.setOnUtteranceCompletedListener（新OnUtteranceCompletedListener（）{

        @覆盖
        公共无效onUtteranceCompleted（字符串utteranceId）{

            runOnUiThread（新的Runnable（）{

                @覆盖
                公共无效的run（）{
                //用户界面的变化
                }
            }）;
        }
    }）;

 }
}）;


HashMap的＆LT;字符串，字符串＆GT; PARAMS =新的HashMap＆LT;字符串，字符串＆GT;（）;

params.put（TextToSpeech.Engine.KEY_PARAM_UTTERANCE_IDstringId）;

tts.speak（文本讲，TextToSpeech.QUEUE_FLUSH，则params）;
 

I am trying to get the Android TTS API to read my "utterance" and then call the onUtteranceCompleted() listener unsuccessfully. I've registered my TTS object and it returns SUCCESS, so I can't figure out for the life of me why my callback isn't getting called.

I've tried searching for help, but it seems others have difficulty with this too. Am I missing something simple?

Thanks for any help you can offer.

解决方案

Call the setOnUtteranceCompletedListener inside the onInit function of the tts object.

If you want to make any changes to the UI on the call of the onUtteranceCompleted function, add the code inside a runOnUIThread method.

And do remember to add the Hashmap param value while calling the speak() function

Example :

TextToSpeech tts= new TextToSpeech(context, new OnInitListener() {

 @Override
 public void onInit(int status) {

    mTts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {

        @Override
        public void onUtteranceCompleted(String utteranceId) {

            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                //UI changes
                }
            });
        }
    });

 }
});


HashMap<String, String> params = new HashMap<String, String>();

params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");

tts.speak("Text to Speak",TextToSpeech.QUEUE_FLUSH, params);
