I have 3 tabs in one of my android guis and the second one contains one which downloads images from the internet! The problem is that when I switch between the tabs and I pass through the gridview I see a non user-friendly lag. How can I avoid this? I want a smooth behavior. Is it good solution to pause the downloads in every tab switch and resume them after the change?

What are you using to download the images and put them into the GridView? I have implemented functionality similar to yours (with a gridView being the large portion of one of the tabs). You should use a rather efficient tool called the UniversalImageLoader. It will lazy load the GridView and should eliminate any semblance of a lag if you implement caching correctly.

  • Thanks for your answer.I use the code from [android-developers](http://developer.android.com/training/displaying-bitmaps/index.html). it uses the cache and I think that it using it very efficient as it is in display bitmaps efficient section. My thought about having a smoother behavior is to pause download work every time I switch tab and resume when the switch have been made! – user2065529 Mar 27 '13 at 18:46
