推荐答案

可绘制对象必须是操作系统可访问的，因此必须可读.

The drawable needs to be accessible to the operating system, so it has to be readable.

如果您确实想确保它的安全，则可以考虑将其加密存储为原始资产，然后加载它，将其解密为ByteStream并将其传递给BitmapFactory.当然，这会对性能产生轻微的影响，并且将迫使您手工编写很多本可以用XML轻松完成的工作.否则，

If you really want to keep it secure, you could consider storing it encrypted as a raw asset, then load it, decrypt it into a ByteStream and pass it into the BitmapFactory. That, of course, has slight performance ramifications and will force you to hand-code a lot of stuff that you could have easily done in XML otherwise.

总而言之，窃取数据的方法有很多-如果它是可绘制的，人们可以截取屏幕截图.

That all aside, there are many ways to steal data - if it's a drawable, people could just take a screenshot.
