更新下版本，最新版本是1.1.3

[LiuDongCai]

好的，新版本已经解决了是吗

[xiaohaibin]

对的

[LiuDongCai]

升级1.1.3之后

[xiaohaibin]

你的调用方式是啥

[LiuDongCai]

[LiuDongCai]

上面是初始化

下面是调用

[LiuDongCai]

每次移动地图，都会重新设置dataList，然后重新调用

[xiaohaibin]

每次刷新后就会报这个错么，正常调用这个方法，viewpager已经重新创建了应该不会导致这个问题

[LiuDongCai]

我这边调试没出现，但是线上用户会出现

1.1.2版本不会，升级1.1.3之后就出现了

[xiaohaibin]

出现问题的设备型号是啥，我复现看看

[LiuDongCai]

[LiuDongCai]

[LiuDongCai]

感觉是刷新设置不同数目的data进去导致的？

[xiaohaibin]

对，这样，你在调用setbannerData方法之后获取viewpager的适配器调用notify试试，我一直没复现出来，因为本身这个方法里面已经重建viewpager，再次设置数据已经是新的适配器了

[LiuDongCai]

好，不过我也没复现，不知道这样设置有无效果，你那边sdk也加一个notifydata？这样好像比较保险。 目前线上我是降到了1.1.2的，后面我再看下改一下。

代码方面我已经是setBannerData for(int i =0;i<mDetailPhotoList.size();i++){ BannerImgInfo bannerImgInfo = new BannerImgInfo(mDetailPhotoList.get(i)); bannerImgInfoArrayList.add(bannerImgInfo); } mPager.setBannerData(R.layout.fragment_house_detail_pic_other,bannerImgInfoArrayList);

[xiaohaibin]

版本是最新的吗

[binbinyYang]

com.github.xiaohaibin:XBanner:androidx_v1.1.2',

[binbinyYang]

作者 能看看是什么问题导致的吗 还是报这个错

[xiaohaibin]

更新到最新的版本试试呢，偶现还是必现的，这个，本地能复现嘛

[xiaohaibin]

https://www.cnblogs.com/Sharley/p/9166675.html 参考这个试试

[binbinyYang]

现在用的是V1.1.2我在自己代码里面加了 notifyDataSetChanged 如下代码 for(int i =0;i<mDetailPhotoList.size();i++){ BannerImgInfo bannerImgInfo = new BannerImgInfo(mDetailPhotoList.get(i)); bannerImgInfoArrayList.add(bannerImgInfo); }

                mPager.setBannerData(R.layout.fragment_house_detail_pic_other,bannerImgInfoArrayList);
                if(mPager.getViewPager()!=null && mPager.getViewPager().getAdapter()!=null) {
                    mPager.getViewPager().getAdapter().notifyDataSetChanged();
                }

[binbinyYang]

for(int i =0;i<mDetailPhotoList.size();i++){ BannerImgInfo bannerImgInfo = new BannerImgInfo(mDetailPhotoList.get(i)); bannerImgInfoArrayList.add(bannerImgInfo); }

                mPager.setBannerData(R.layout.fragment_house_detail_pic_other,bannerImgInfoArrayList);
                if(mPager.getViewPager()!=null && mPager.getViewPager().getAdapter()!=null) {
                    mPager.getViewPager().getAdapter().notifyDataSetChanged();
                }

[binbinyYang]

拿到数据集合 bannerImgInfoArrayList 然后 setBannerData 然后在判断 后notifyDataSetChanged

[xiaohaibin]

这样设置还是不行么

[binbinyYang]

是的 还是在一直报错 友盟统计的崩溃率一直有 我此时此刻在公司看的数据

[binbinyYang]

作者你好 方便加你微信吗 针对这个问题一直在报错 有点困扰我们，我能复现出这个崩溃bug

[xiaohaibin]

已处理
