我将我的图像文件转换为字节并使用下面给出的内容值插入数据库。我需要将图像作为字节存储到博客数据库字段中
String fileName="/sdcard/"+pkDelivery+".png";
Bitmap bMap = BitmapFactory.decodeFile(fileName);
imgSignature.setImageBitmap(bMap);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bMap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
String aa =byteArray.toString();
ContentValues initialDelay15 = new ContentValues();
dbAdapter = new DatabaseAdapter(this);
dbAdapter.open();
initialDelay15.put("Signature",
byteArray);
dbAdapter.UpdateRecord("tblDelivery", initialDelay15, "PKDelivery"
+ "=" + pkDelivery, null);
当尝试将图像转换为字节时，字节数组显示如下所示的值，如下所示
