  • Additionally, you can feel free to use the Search bar selection mechanism as a replacement for tabs since it’s really just a fast pivot on a data set. If you have more than 3 data sets, tabs become problematic since no more than 3 can be onscreen at once. For example, look at how we implemented the Profile switching mechanism below:

  • QuickActions can be used as a replacement for our traditional dialog invoked by long press.
  • The dashboard pattern serves as a home orientation activity for your users. It is meant to include the categories or features of your application. We recommend including an Action bar on this screen as well. The dashboard can be static or dynamic. For example, in the case of our dashboard for Twitter, we used the goodness of Live Wallpapers introduced in 2.1 to create an animated dashboard complete with real-time trend bubbles and the Twitter bird silhouette.
  • You keep a search history so users upon returning to the search activity can have quick one-button access to previous searches.

Lazy Loading Images in a ListView - consensus approach? - Android Developers | Google G... - 0 views

  • I haven't looked in details at the 3 other approaches but I know that a big difference between what I do in Shelves and what I've seen done in other places is how user interaction is handled. Shelves listens to scroll events on the ListView and tries to identify taps vs scrolls vs fling to always give priority to the UI. For instance, when you touch the screen to stop a fling, Shelves starts loading images, but does so only after a very short delay so that if you are touching the screen to fling some more, the fling animation won't stutter because of the extra work load. But that's details.
