我如何测试当前在特定 ImageView 中的图像并为每个可能的图像定制输出？

Question

我们已经设法获取它，因此当单击第一个按钮时，图像将从该列表中正确设置。但是，现在我需要将该信息发送到 handleUSPKeep 方法，并且我需要将设置到 ImageView 中的图像的列表 ID 设置到 handleUSPKeep 方法中 if 语句之前的行中。我创建了一个名为 i 的全局 int 变量，并将 ID 放在应该去的地方。有没有办法可以在程序结束时设置七种方法中的每一种我是什么？

Answer 1

如果您可以设置这些图像中的每一个发生的时间（即设置一个标记来标记有一个图像切换），并且没有大量的图像那么我会使用枚举作为解释 here。然后很棒的是，您可以使用 switch 语句来遍历每个场景，而无需使用多个 "if" 语句！ :)

Answer 2

我建议您使用 List 来列出您的图片。您不能使用它的路径比较图像。看看这个演示，
