39 <p><em>Descendant navigation</em> is navigation down the application's information hierarchy. This is described in <a href="{@docRoot}training/design-navigation/descendant-lateral.html">Designing Effective Navigation</a> and also covered in <a href="{@docRoot}design/patterns/app-structure.html">Android Design: Application Structure</a>.</p>
41 <p>Descendant navigation is usually implemented using {@link android.content.Intent} objects and {@link android.content.Context#startActivity startActivity()}, or by adding fragments to an activity using {@link android.app.FragmentTransaction} objects. This lesson covers other interesting cases that arise when implementing descendant navigation.</p>
45 <p>In a <em>master/detail</em> navigation flow, a <em>master</em> screen contains a list of items in a collection, and a <em>detail</em> screen shows detailed information about a specific item within that collection. Implementing navigation from the master screen to the detail screen is one form of descendant navigation.</p>
47 <p>Handset touchscreens are most suitable for displaying one screen at a time (either the master or the detail screen); this concern is further discussed in <a href="{@docRoot}training/design-navigation/multiple-sizes.html">Planning for Multiple Touchscreen Sizes</a>. Descendant navigation in this case is often implemented using an {@link android.content.Intent} that starts an activity representing the detail screen. On the other hand, tablet displays, especially when viewed in the landscape orientation, are best suited for showing multiple content panes at a time: the master on the left, and the detail to the right). Here, descendant navigation is usually implemented using a {@link android.app.FragmentTransaction} that adds, removes, or replaces the detail pane with new content.</p>
