Choose/Take 来自 Android 中 AlertDialog 的照片
Choose/Take a Photo from AlertDialog in Android
在我的应用程序中有一个弹出窗口 activity，用户可以在其中编辑他的信息。
我正在使用 this 教程显示来自 gallery/camera 的照片。我有一堆 xml 个文件，每个警报对话框一个。
在我的 onActivityResult 变量中 editPhoto 无法识别。它在我的 editProfilePhoto 中声明。我尝试了很多方法，将其声明为 final，在 onCreate 中声明，移动 onActivityResult，等等，但我总是会遇到一些不同的错误。
解决此问题的最佳方法是什么。
我的错误：
Error:(353, 13) error: cannot find symbol variable editPhoto

全局声明 editphoto
ImageView editPhoto;
目前 editPhoto 对象范围仅在 clicklistner 中，这就是为什么您不能在 onActivityResult 方法中使用的原因。
您在 onClick 方法中创建并声明了 editPhoto。它应该像 Hitesh Gehlot 所说的那样在全球范围内声明。
在我的应用程序中有一个弹出窗口 activity，用户可以在其中编辑他的信息。 我正在使用 this 教程显示来自 gallery/camera 的照片。我有一堆 xml 个文件，每个警报对话框一个。
在我的 onActivityResult 变量中 editPhoto 无法识别。它在我的 editProfilePhoto 中声明。我尝试了很多方法，将其声明为 final，在 onCreate 中声明，移动 onActivityResult，等等，但我总是会遇到一些不同的错误。
