（原创）分享自己写的几个工具类（七）Bitmap和String互转

话不多说，直接上代码

bitmapToString

    public static String bitmapToString(Bitmap bitmap) {
        //将Bitmap转换成字符串
        String string = null;
        ByteArrayOutputStream bStream = new ByteArrayOutputStream();
        //参数1为转换的图片格式，参数二为压缩的百分比，这里是10%
        bitmap.compress(Bitmap.CompressFormat.JPEG, 10, bStream);
        byte[] bytes = bStream.toByteArray();
        string = Base64.encodeToString(bytes, Base64.DEFAULT);
        return string;
    }

stringToBitmap

    public Bitmap stringToBitmap(String string) {
        // 将String转换成Bitmap类型
        Bitmap bitmap = null;
        try {
            byte[] bitmapArray;
            bitmapArray = Base64.decode(string, Base64.DEFAULT);
            bitmap = BitmapFactory.decodeByteArray(bitmapArray, 0,
                    bitmapArray.length);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return bitmap;
    }
