更新 viewPager 时发生 ANR

Question

我在尝试更新图像查看寻呼机时遇到 ANR 问题。有人有想法吗？下面是我的代码。我怀疑当我执行 setcurrentItem 时得到这个 ANR : Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 5.

private void setRelavantColourPic(ValueList valueList){
   if(valueList.getPictureId() != 0 && productImages != null && productImages.size() > 0){
       i = 0;

       for (ProductPictureList productPictureList : productImages ){
           int pictureId =  Integer.parseInt(productPictureList.getPictureId());
           i ++;
           if(pictureId == valueList.getPictureId()){
               foundIndex = i-1;
           }
       }



       mDelayHandler.postDelayed(
               mRunnable =   new Runnable() {
                   @Override
                   public void run() {
                       mProductImageViewPager.setCurrentItem(foundIndex);
                   }
               }, 1);
     //  mDelayHandler.post(mRunnable);

   }
}

我认为是递归阻塞了主线程。尝试删除以下语句，

mDelayHandler.post(mRunnable);

它会起作用。
