Convert ByteArrayOutputStream to BufferedImage

Question

I have a ByteArrayOutputStream I have created using the QRGen Qr code generation library, and I want to turn it into a BufferedImage object and present it in an ImageView in Android. How may that be achieved?

Answer 1

Convert the ByteArrayOutputStream to Byte array

byte[] data = baos.toByteArray(); //baos is your ByteArrayOutputStream object

them create a bitmap out of it using the BitmapFactory

Bitmap bmp = BitmapFactory.decodeByteArray (data,0,data.length, null);

them take your ImageView and set its bitmap

imageView.setImageBitmap(bmp);
