推荐答案

您已使用Android标记了您的问题。 javax.imageio.ImageIO 不属于Android平台，所以遗憾的是你无法使用它。相反，您需要使用Android SDK中可用的内容来读取和存储图像。

You have tagged your question with Android. javax.imageio.ImageIO is not part of the Android platform, so unfortunately you can't use it. Instead you need to use what's available in the Android SDK for reading and storing images.

看一下位图和 BitmapFactory 类作为起点。

Have a look at the Bitmap and BitmapFactory classes for a starting point.

这些类包含必要的读取方法（ BitmapFactory.decode *（...）方法）并写入（ Bitmap.compress（...）方法）。

These classes contains the necessary methods to read (BitmapFactory.decode*(...) methods) and write (Bitmap.compress(...) method).
