推荐答案

您的代码对于将位图放入额外内容是正确的，并且对于小图像的我来说效果很好.但是似乎Parcelable extra 的大小是有限制的.请参阅 http://groups.google.com/group/android-developers/browse_thread/thread/7322a84adcfee567?pli=1.

Your code is correct for putting bitmaps into the extras and works fine for me with small images. But it seems that there is a limit for the size of the Parcelable extra. See http://groups.google.com/group/android-developers/browse_thread/thread/7322a84adcfee567?pli=1.

您可能希望先存储图像，然后再将 URI 移交给存储位置.

You might want to store the image first and only hand over the URI to the store location.

按照 udaykiran 的建议对位图使用公共静态字段违反了许多面向对象的原则，我什至不知道从哪里开始.

Using a public static field for the bitmap as suggested by udaykiran violates so many OO principles I don't even know where to start.
