How to display the image in listview by decoding the image from webserver?

Question

I am trying to post my phone contact details like name,number,email,address and photo to the webserver in json fromat,where the image is encoded in Base64 format. In server side the image is being stored as BLOB type in the database. I'm trying to retreive and display all the data from the server in a listview. I am able to display all data except image.

Here is the code:

For Encoding the image:

ByteArrayOutputStream byteArrayBitmapStream = new ByteArrayOutputStream();
                          bitmap.compress(Bitmap.CompressFormat.PNG, COMPRESSION_QUALITY, byteArrayBitmapStream);
                          byte[] b = byteArrayBitmapStream.toByteArray();
                          String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);

jsonObject.accumulate("imageData",encodedImage);

For Decoding the image:

String image=(String)jsonObject.get("image");
byte[] byteArray =  Base64.decode(jsonObject.getString("imageData").getBytes(), Base64.DEFAULT) ;

Bitmap bmp1 = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

HashMap<String, Object> map = new HashMap<String, Object>();
map.put(TAG_IMAGE,bmp1);

Please help me out to display the image in listview.Thanks...

I think you should use Universal Image Loader for Android library.

This will do all complex stuff for you to display image from web server with many customization option.

Thanks for your answer. But I'm not taking any image url.. I'm storing the image as BLOB type in database. How can I do without fetching back the image url? – user2879697 Dec 16 '13 at 07:44
