编译器没有看到新方法名称 - 构建问题但是 运行 时间错误。 "java.lang.IllegalStateException: Could not find a method"
Compiler doesn't see new method name - build issue but run time error. "java.lang.IllegalStateException: Could not find a method"
我以常规方式从现有的 class 创建了一个新的 Activity class，然后从我的 ScanActivity.class 中剪切和粘贴代码，因为新的class 会非常相似。
新的 class 是 SenderActivity2.class。我还更改了 XML onClick 处理程序，使其具有 onPicButtonClicked 侦听器，而不是 ScanActivity class.
的 onScanButtonClicked
gradle 构建和项目构建一样有效，但在 运行 按钮单击时失败。
你可以在logcat中看到它还在寻找onScanButtonClicked方法。我实际上进去并将方法名称改回 onScanButtonClicked，即使该方法在另一个 class 中，看看它是否会以某种方式工作。它做了。此外，当我第一次创建新的 class 并且自动生成 XML 时，为 XML 创建的名称存在问题。我认为这可能是问题根源的重要线索。我删除了主目录中的 .gradle 文件并强制它重建所有内容，但这没有帮助。希望你们中的一些人遇到过类似的事情。我知道某处有一个文件需要重建..只是不知道它是什么或在哪里。
