onUtteranceCompleted不会被调用？ [英] onUtteranceCompleted does not get called?

问题描述

即使我正确设置它：

HashMap<String, String> myHashRender = new HashMap<String, String>();
myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "utid");
mTts.speak("Speak something", TextToSpeech.QUEUE_ADD, myHashRender);

也

mTts.setOnUtteranceCompletedListener(this);

在OnInit函数返回成功。 仍然是onUtteranceCompleted不会被调用。虽然有重复的问题，但没有在那里我能找到答案。

in the onInit function return success. Still the onUtteranceCompleted does not get called. Though there are duplicate questions, but no where I could find the answer.

我的动态也实现OnUtteranceCompletedListener。

My Activity also implements OnUtteranceCompletedListener.

请帮忙。

推荐答案

调用setOnUtteranceCompletedListener的TTS对象的OnInit函数中。

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

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。

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

和千万要记得添加HashMap的参数值，同时调用说话（）函数

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

例如：

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);
