连续调用TextToSpeech.OnInitListener.onInit(int)

Question

我得到的报道称,在一些(并非所有)HTC Desire HD(FRF91,2.2)和HTC EVO 4G(PC36100 | 3.29.651.5,2.2)上,TextToSpeech.OnInitListener.onInit(int)被重复调用(在少数几个空间内超过1500次)秒)在同一个对象上.任何我的其他用户(或与其他Desire HD用户)AFAICT不会发生此问题.

代码是:

TextToSpeech tts = new TextToSpeech(context, new TextToSpeech.OnInitListener() {
    private int mCallCount = 0; // trying to investigate potential infinite loops

    @Override
    public void onInit(int status) {
        if ((mCallCount % 100) == 1) {
            // report this
        }
        mCallCount++;
    }
});

任何想法？

编辑:我也试过调用该shutdown()方法(第一次检测到多个侦听器调用)但这似乎没有帮助.

也许您应该使用自己的中间方法来解决它，例如：

private long lastCall = 0;
private long deepBreath = 5*1000; //5 seconds
private boolean hasRested;

TextToSpeech tts = new TextToSpeech(context, new TextToSpeech.OnInitListener() { 
    @Override 
    public void onInit(int status) { 
        long thisCall = Calendar.getInstance().getTimeInMillis();
        intermediaryMethod(status, thisCall);
    } 
}); 

//new method
public void intermediaryMethod(int status, long thisCall) {
    hasRested = (thisCall-lastCall)>=deepBreath;
    if (hasRested) {
        lastCall = thisCall;
        //do something about 'status'
    }
}
