How do I load a blurred image first, in imageview, and then make it sharp, in order to enhance user experience, for android?

I'm working on an application in which I need to download lots of images. The images are to be seen in the fullscreen mode. Therefore, I wanted to know how to load an image, speedily, to make the application more responsive and enhance user experience. I would like to, atleast, show a blurred image first and than make it sharp. Thanks.

You're looking for "progressive image rendering", which can be done in a variety of different image formats, including png, jpeg, gif, etc. The next time you're going to save an image in a good graphics program, select one of those formats and take a look at your save options. You should have an option to save an "interlaced" image.

use BitmapFactory.Options.inSamleSize to load a downsampled version of the image. Then load the bigger image and do a fade transition using a TransitionDrawable
