Question

我的recyclerview有问题。我有删除列表中的项目的功能。当最后一项没有显示时，它工作正常。但是当最后一项显示在屏幕（列表）的末尾时，我从列表中删除项目后出现错误。

这是我的logcat：

我删除了这样的项目：

public void delete(Entity entity) {
      entities.remove(entity);
      notifyDataSetChanged();
}

这里有什么问题？对我的问题有任何建议吗？谢谢！

我想可能是这个错误的原因是删除项目我从Dispoable的rx线程调用？当我在活动中删除项目时，它的工作正常。

您可以使用$httpProvider.responseInterceptors.push("YourInterceptor");或Picker.route('/generate/getPdf', function(params, req, res, next) { var doc = new PDFDocument({size: 'A4', margin: 50}); doc.fontSize(12); doc.text('PDFKit is simple', 10, 30, {align: 'center', width: 200}); res.writeHead(200, { 'Content-Type': 'application/pdf', 'Content-Disposition': 'attachment; filename=test.pdf' }); doc.pipe(res); doc.end(res); });方法notifyItemRangeChanged适配器。

删除列表中的最后一项时，RecyclerView错误
