//我在对抽屉布局进行充气时出现此错误。我不确定这是否是由于印刷造成的。请帮助我。代码在28版上运行良好，但升级到29/30版时崩溃了

您的问题出在uk.co.chrisjenx.phraphic.ReflectionUtils.getValue（ReflectionUtils.java:29）。它使用反射来获得一个场。如果它在更新时中断，则很可能假设某个字段已不存在，并且它不应该依赖该字段。另请参阅：该库不再维护，您应该升级到版本3。您可以为其提供解决方案吗？解决方案：不要使用该库。升级到版本3。没有其他解决方案不会花费数天->数周的编码时间。谢谢。你救了我一天。替换：）花了5分钟。再次感谢。你的问题在uk.co.chrisjenx.phraphic.ReflectionUtils.getValue（ReflectionUtils.java:29）。它使用反射来获得一个场。如果它在更新时中断，则很可能假设某个字段已不存在，并且它不应该依赖该字段。另请参阅：该库不再维护，您应该升级到版本3。您可以为其提供解决方案吗？解决方案：不要使用该库。升级到版本3。没有其他解决方案不会花费数天->数周的编码时间。谢谢。您节省了我的时间。替换：）花费了5分钟。再次感谢。
