问题
I saw a lot of implementations of smooth downloading images from web and showing them in listView with cache. Now I have the following situation: I'm storing images to SDCard and sometimes my listView shows them instead of images from web resource. In this case navigation in listView is not smooth. Do you know any good implementation of listView with image from sdCard?

Multithreading is the answer! http://android-developers.blogspot.com/2010/07/multithreading-for-performance.html Just ignore the the sections for downloading, but idea is the same!
Then check this code : Lazy load of images in ListView
