Android图片二进制与Bitmap之间的转换

    public byte[] getBitmapByte(Bitmap bitmap){
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
        try {
            out.flush();
            out.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return out.toByteArray();
    }
    
    
    public Bitmap getBitmapFromByte(byte[] temp){
        if(temp != null){
            Bitmap bitmap = BitmapFactory.decodeByteArray(temp, 0, temp.length);
            return bitmap;
        }else{
            return null;
        }
