android.view.InflateException：二进制 XML 文件行 #49：膨胀 class android.widget.ImageView 时出错
android.view.InflateException: Binary XML file line #49: Error inflating class android.widget.ImageView
您好，当我尝试从适配器 class 调用片段选项卡中的回收器视图时，出现以下错误。图像视图出现错误。我已经搜索了很多，但没有解决方案。我的图像源在 /res/drawable 文件夹中。布局文件在其他 Activity class 中工作正常，但仅在这一个中出错。我试图创建另一个没有图像视图的布局文件并且工作正常。感谢任何帮助。提前致谢。
