android – 当工作线程工作时,UI变得不稳定

> Thread.yield()后处理一大堆工作.
>限制更新发布到UI线程,最小500毫秒间隔(导致更少的重新绘制).
>使工作人员处理优先级数据桶,这个重点是更新用户正在与之进行交互的视图.

现在整个UI真的很懒,但没有滞后.

这是我的工作人员的调度方法(实际工作由Process方法完成)：

//--low priority
Thread.currentThread().setPriority(Thread.MIN_PRIORITY);

//--as long as there's more work to do,and not cancelled--
while (mPriorityBuffer.hasNext() && !isCancelled()) {

    //--get the work with highest priority--
    Work next = mPriorityBuffer.getNext();

    //--do work--
    update u = mProcessor.process(next);

    // collect updates for main thread
    mupdates.push(u);

    long timeNow = Calendar.geTinstance().getTimeInMillis();
    if(timeNow - timeLast > 500){
        //--its been quite a while Now,update ui--
        postupdatesToMainThread();
        timeLast = timeNow;
    }

    //--let UI thread work on updates--
    Thread.yield();
}
