Swipe views 15allow the user to efficiently move from item to item using a simple gesture and thereby make 16browsing and consuming data a more fluent experience.</p> 17<h2 id="detail-views">Swiping Between Detail Views</h2> 18 19<p>An app's data is often organized in a master/detail relationship: The user can view a list of 20related data items, such as images, chats, or emails, and then pick one of the items to see the 21detail contents in a separate screen.</p> 22 23<img itemprop="image" src="{@docRoot}design/media/swipe_views.png"> 24<div class="figure-caption"> 25 Master (left) and detail (right) views. 26</div> 27 28<p>On a phone, since the master and detail are on separate screens, this typically requires the user to 29jump back and forth between the list and the detail view, aka "pogo-sticking".</p> 30<p>In cases where users will want to view multiple detail items in succession, avoid pogo-sticking by 31using the swipe gesture to navigate to the next/previous detail view.</p> 32 33<img src="{@docRoot}design/media/swipe_views2.png"> 34<div class="figure-caption"> 35 Navigating between consecutive email messages using the swipe gesture. If a view contains content that exceeds the width of the screen such as a wide email message, make sure the user's initial swipes will scroll horizontally within the view. Once the end of the content is reached, an additional swipe should navigate to the next view. In addition, support the use of edge swipes to immediately navigate between views when content scrolls horizontally. 36</div> 37 38<img src="{@docRoot}design/media/swipe_views3.png"> 39<div class="figure-caption"> 40 Scrolling within a wide email message using the swipe gesture before navigating to the next message. 41</div> 42 43<h2 id="between-tabs">Swiping Between Tabs</h2> 44 45<div class="cols"> 46 <div class="col-5"> 47 48 <div class="framed-nexus5-port-span-5"> 49 <video class="play-on-hover" autoplay> 50 <source src="{@docRoot}design/media/swipe_tabs.mp4" type="video/mp4"> 51 <source src="{@docRoot}design/media/swipe_tabs.webm" type="video/webm"> 52 <source src="{@docRoot}design/media/swipe_tabs.ogv" type="video/ogg"> 53 </video> 54 </div> 55 <div class="figure-caption"> 56 People app with swipe gesture navigation between top-level screens. 57 <div class="video-instructions"> </div> 58 </div> 59 60 </div> 61 <div class="col-8"> 62 <p>If your app uses action bar tabs, use swipe to navigate between the different views.</p> 63 <div class="vspace size-1"> </div> 64 65 <h2 id="checklist">Checklist</h2> 66 <ul> 67 <li> 68 <p>Use swipe to quickly navigate between detail views or tabs.</p> 69 </li> 70 <li> 71 <p>Transition between the views as the user performs the swipe gesture.
