Java - Code examples

Composed UI

Composed UI, an example application for Nokia Asha software platform, combines three different user interface implementations for presenting list based data: Split view, list view and grid view. The split view and the grid view utilise custom, grid layout. The list items in the split view are also custom items. All the views in the application are Form based. The example also demonstrates how to manage persistent data including storing and restoring the application state.
