Android Can'；我无法从毕加索那里获得imageView

来自Json的ImageLink

我知道问题出在ImageView中，但我不知道如何解决，相信我，我在网上搜索了一个解决方案，但没有找到

如果需要其他材料，可以自由询问

为什么要在onPostExecute（）中重复毕加索加载行？抱歉，我编辑了，我忘记删除它，因为我几乎每次都复制它来解决问题，但我失败了，将OnCreate（）中和super.OnCreate（）下的所有代码放在onCreateView（）中，然后重试。确保imageOrdersN属于fragment\u orders\u tabs Layout我按您所说的那样输入代码，仍然是相同的错误，但imageOrdersN不属于fragment\u orders\u tab，而是属于fragment\u orders\u list\u Item谢谢，先生，我知道了

OrderTab
