提问by rascal2210

I know how to read a bitmap file into a byte array. How is the byte array then converted to a Java Bitmap?

我知道如何将位图文件读入字节数组。然后字节数组如何转换为 Java 位图?

Use BitmapFactoryif you already have your byte array:

使用BitmapFactory如果你已经有你的字节数组:

Bitmap bitmap = BitmapFactory.decodeByteArray(yourByteArray, offset, length);

回答by rascal2210

Skip the byte array if you want: Bitmap bitmap = BitmapFactory.decodeFile(filename);

如果需要,请跳过字节数组:Bitmap bitmap = BitmapFactory.decodeFile(filename);
