我在android中使用回收站视图来显示数据列表。我也在视图持有者类中使用链接预览。但我的回收者视图未显示任何数据，该页面为空。
及其显示错误-
android.view.InflateException: Binary XML file line #0: Binary XML file line #0: Error inflating class <unknown>
我尝试了很多事情，但是没有从那里得到任何输出。我已经检查了我的xml文件代码。哪个是对的。我也检查了代码，但没有发现问题。

答案 0 :(得分：0)
投资3-4小时后，我的问题得到了解决。我在膨胀布局时使用的是getContext（）而不是上下文（通过构造函数来实现）。小愚蠢的错误。
