Question

我正在使用图片共享元素创建应用程序。一切正常，除非我尝试在模拟器上运行我的应用程序，它无法按照代码显示正确的输出。另一方面，当我在Android设备上测试我的应用程序时，它会显示Unexpected Error。我试图重启我的设备并创建了一个新的模拟器，但它们都没有对我有帮助。

违规代码，FullImageActivity上的第55行是

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.id.full_image_view);

这是LogCat

检查您的第二个参数类型是否为资源ID。您应该为此特定资源提供有效的参数类型即使用R.Drawable.FILENAME 你正在做的是你为Resources提供一个id参数，导致你Unexpected Error 它就像用柴油为你的汽油车加油：x
