java.lang.IllegalStateException：未找到所需的视图 - butterknife 有时不工作

Question

如果有时想在一个月后发布它，我会遇到异常。每次我必须删除构建文件夹时，错误就会消失。因此，长时间运行保持这种状态是有风险的，因为有时开发人员可能会忘记检查此 activity 是否打开。

到目前为止，奇怪的是它只发生在一个文件中 ProductListActivity.kt

这个运行time 错误看起来像常见错误是否需要 Gradle 配置来修复它。

如何彻底摆脱它？

我从日志中看到您正在使用 kotlin，因此您可以用视图绑定（出现错误的区域）替换您的代码而不是 butterknife

java.lang.IllegalStateException: Required view not found - butterknife not working sometimes

android

kotlin
