The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged!

你好，使用该库有时会发生如题错误： 发生该错误的机型有：MI 4LTE ，HM NOTE 1S, MI 3W。操作系统均为 android 4.4.4 下面是详细报错： java.lang.IllegalStateException: The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged!

具体的情景是怎样的呢？比如某个图片加载失败，或者横竖屏切换，或者你手动去删除某个Item等

[Jack-Xiao]

是直接使用在App 首页某fragment中的轮播图。 在onCreateView某方向异步取得数据然后调用： for (int i = 0; i < list.size(); i++) { DefaultSliderView textSliderView = new DefaultSliderView(mContext); Log.d("imag..", list.get(i) + "..."); textSliderView .image(list.get(i)) // 后台传过来的图片url .setScaleType(BaseSliderView.ScaleType.Fit) .showImageResForEmpty(R.drawable.default_image_in_no_source) .showImageResForError(R.drawable.default_image_in_no_source); mAnimCircleIndicator.addSlider(textSliderView); } mAnimCircleIndicator.setIndicatorPosition(InfiniteIndicatorLayout. IndicatorPosition.Center_Bottom); mAnimCircleIndicator.startAutoScroll();

然后在该fragment 的onDestoryView调用
@Override public void onDestroyView() { super.onDestroyView(); mAnimCircleIndicator.stopAutoScroll(); ButterKnife.reset(this); }

1)我遇见的情况是（偶尔）在首次进入App轮播图的时候出现 。 2)有在stackoverflow中查到也有人出现这种情况，“ The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged!” 然而还是不知道是什么原因造成的，因为你的内部都有调用notifyDataSetChanged. 希望能帮忙尽情解决。

我遇见的情况之一是: 在图片未加载出来， 然后进行手滑动快速切换到之后的图片。
其实不是很明白为什么getCount 方向要写成
@Override public int getCount() { return isLoop ? getRealCount() * 100 : getRealCount(); } 这样，恩， 我比较菜， 不明白。

[lightSky]

是为了得到一个较大的数，以便可以较长时间的轮循，而getView中处理的时候是取余的

[lightSky]

另外你应该在onPause 和 onResume中进行stop 和 start，这样比较节省资源

[Jack-Xiao]

喔，那这Issue的呢？ 它是可以重现的。
