Abstract
Techniques are provided for optimizing operations, such as scrolling, that move rendered views for items in a collection relative to a viewable window. An application initially renders only those views within the viewable window. In a background process, the application also builds a pool of rendered views that are outside of the viewable window. Background rendering occurs is timed to not interfere with the user's experience. The pool is constrained in size so as not to over-utilize device memory. When a new item is scrolled or otherwise moved into the viewable window, the application first checks the pool to determine if a view of the new item is already rendered. If so, the application simply displays the pre-rendered view, resulting in minimal processor utilization. The application thus provides the user with a 'smoother' scrolling experience. A priority queue for identifying views to replace or overwrite is also discussed.
