¿Cómo puedo convertir ByteArrayInputStream a jpeg y mostrar en android móvil?

1.i obtener los datos de la cámara de Android convertir a bitmao

if (mBitmap == null) //create Bitmap image first time { Camera.Parameters params = camera.getParameters(); width_ima = params.getPreviewSize().width; height_ima = params.getPreviewSize().height; mBitmap = Bitmap.createBitmap(width_ima, height_ima, Bitmap.Config.RGB_565); mRGBData = new int[width_ima * height_ima]; } decodeYUV420SP(mRGBData, data, width_ima, height_ima); mBitmap.setPixels(mRGBData, 0, width_ima, 0, 0, width_ima, height_ima);

2. enviar los datos con udp

 ByteArrayOutputStream byteStream = new ByteArrayOutputStream(); mBitmap.compress(Bitmap.CompressFormat.JPEG, 50, byteStream); // !!!!!!! change compression rate to change packets size byte data[] = byteStream.toByteArray(); Log.e(TAG, "SIZE: " + data.length); int nb_packets = (int) Math.ceil(data.length / (float)DATAGRAM_MAX_SIZE); int size = DATAGRAM_MAX_SIZE; /* Loop through slices */ for(i = 0; i < nb_packets; i++) { if(i >0 && i == nb_packets-1) size = data.length - i * DATAGRAM_MAX_SIZE; /* Set additional header */ byte[] data2 = new byte[HEADER_SIZE + size]; data2[0] = (byte)frame_nb; data2[1] = (byte)nb_packets; data2[2] = (byte)i; data2[3] = (byte)(size >> 8); data2[4] = (byte)size; /* Copy current slice to byte array */ System.arraycopy(data, i * DATAGRAM_MAX_SIZE, data2, HEADER_SIZE, size); try { size_p = data2.length; DatagramPacket packet = new DatagramPacket(data2, size_p, serverAddr, 9000); socket.send(packet);

3.i recibir los datos en android móvil

 while (true) { try { socket.receive(packet); System.out.println("已经收到信息了!!!"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } byte[] data = packet.getData(); int frame_nb = (int)data[0]; int nb_packets = (int)data[1]; int packet_nb = (int)data[2]; int size_packet = (int) ((data[3] & 0xff) << 8 | (data[4] & 0xff)); if((packet_nb==0) && (current_frame != frame_nb)) { current_frame = frame_nb; slicesStored = 0; imageData = new byte[nb_packets * DATA_MAX_SIZE]; } if(frame_nb == current_frame) { System.arraycopy(data, HEADER_SIZE, imageData, packet_nb * DATA_MAX_SIZE, size_packet); slicesStored++; } /* If image is complete display it */ if (slicesStored == nb_packets) { ByteArrayInputStream bis = new ByteArrayInputStream(imageData); }

Y mi pregunta es: ¿cómo puedo mostrar los datos ByteArrayInputStream bis en android móvil … Gracias por su respuesta!

Con el fin de convertir ByteArrayInputStream a una imagen jpeg simplemente puede utilizar el siguiente código:

  ByteArrayInputStream bis = new ByteArrayInputStream(imageData); Bitmap bp=BitmapFactory.decodeStream(bis); //decode stream to a bitmap image yourImageView.setImageBitmap(bp); //set the JPEG image in your image view

Espero que esto ayude .. Gracias ..
