Android Bitmap与byte[]之间的转换

1.Bitmap-->byte[]:

public static byte[] Bitmap2Bytes(Bitmap bm) {ByteArrayOutputStream baos = new ByteArrayOutputStream();bm.compress(Bitmap.CompressFormat.PNG, 100, baos);        return baos.toByteArray();}

2.byte[]-->Bitmap:

public static Bitmap Bytes2Bimap(byte[] b) {if (b.length == 0) {return null;}return BitmapFactory.decodeByteArray(b, 0, b.length);}
