即使我设置正确：
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函数中返回成功.
仍然没有调用onUtteranceCompleted.虽然有重复的问题,但没有哪里可以找到答案.
我的活动也实现了OnUtteranceCompletedListener.
请帮忙.
解决方法
调用tts对象的onInit函数中的setOnUtteranceCompletedListener.
如果要在onUtteranceCompleted函数的调用上对UI进行任何更改,请在runOnUIThread方法中添加代码.
示例：
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);
