android image fadein or fadeout

What is the simplest way to fade-in or fade-out an image in android?

I am reading images fr开发者_如何转开发om the SD-card one after the other automatically with no button clicking (like a slideshow) so when the new image comes up i want a fade in or fade out effect

You can use R.anim.fadeout & R.anim.fadein........
