对应此段代码

FlikerProgressBar.class

@Override public void run() { int width = flikerBitmap.getWidth(); try { while (!isStop && !thread.isInterrupted()) { flickerLeft += dp2px(5); float progressWidth = (progress / maxProgress) * getMeasuredWidth(); if (flickerLeft >= progressWidth) { flickerLeft = -width; } postInvalidate(); Thread.sleep(20); } } catch (InterruptedException e) { e.printStackTrace(); } }
