Microsoft 首先优化了他们的布局,以便更好地适应大屏幕,例如在 Outlook 中使用列表详情布局查看展开的电子邮件旁边的电子邮件列表。在可折叠设备或平板电脑上,这两个视图会并排显示或以双窗格模式显示,并用垂直分隔线分隔。用户现在可以轻松浏览收件箱和日历并进行分类,而无需在收件箱和会话视图之间切换。
对于 Teams 应用,他们跨越了设备处于横屏模式时的列表详情布局。这让用户能够在大屏设备上更快速、更高效地访问其内容、聊天内容和文件。
对于 Office,他们还根据文档类型打造了独特的双屏体验,使他们的用户能够充分利用空间,例如 Word 的阅读模式、PowerPoint 的列表-详情布局和 Excel 的扩展画布。

To achieve that, Microsoft knows it's essential to provide an optimal productivity experience for their customers across all devices they use. With the usage of tablets and foldables exploding for productivity apps, Microsoft has been investing in improving the experiences for the Outlook, Teams, and Office apps to give their users a more desktop-like experience on the go.\n\u003e *Teams has a fair share of users on tablets and foldables, and not having optimized experiences for larger form factors was something customers complained about.*\n\u003e\n\u003e Richa Srivastava, Senior Program Manager, Microsoft\n\nWhat they did\n-------------\n\n[Multi-window mode](/develop/ui/compose/layouts/adaptive/support-multi-window-mode) usage has taken off on large screen devices, and companies such as Microsoft have taken advantage of the additional real estate of large screens to provide better experiences for their users. Microsoft made the Outlook, Teams, and Office apps shine on foldables and tablets by optimizing their layouts and incorporating multi-window and [multi-instance](/develop/ui/compose/layouts/adaptive/support-multi-window-mode#multi-instance) capabilities. \n\n### Optimized layouts for large screens\n\nMicrosoft started by optimizing their layouts to better fit the large screen, such as using the list-detail layout for viewing a list of emails next to an expanded email in Outlook. While on a foldable or a tablet, the two views are displayed side by side, or in dual-pane mode, separated by a vertical divider. Users can now easily go through and triage their inbox and calendar without having to switch between inbox and conversation views. \n\nFor the Teams app, they spanned the list-detail layout for when the device is in landscape orientation. This enabled their users to access their content, chats, and files faster and in a more efficient manner when on large screen devices. \n\nFor Office, they also created unique dual-screen experiences based on the document type to enable their users to take advantage of the real estate, such as a reading mode for Word, a list-detail layout for PowerPoint, and an extended canvas for Excel.\n\n### Support for multitasking\n\nWhile the team improved individual app experiences, they also invested in ensuring the apps work well together. Across Teams, Outlook, and Office, Microsoft implemented multitasking features. They made sure the UI was fully resizable so that the apps could seamlessly be transitioned into split-screen or multi-window mode. This helped pair productivity use cases like having a chat open while also working on a document.\n\nThen the apps added functionality to help users be more productive in multi-window mode, like [drag and drop](https://developer.android.com/guide/topics/ui/drag-drop)---enabling drag and drop for text, files, and messages between apps, messages, and events. \n\nLastly, the Office team added multi-instance support which allows users to have multiple instances of the same app side by side, which is useful when viewing two documents simultaneously. The multi-window mode helps in optimized creation with lighter edits and consumption. For Outlook, they also implemented multi-instance, enabling use cases such as composing an email while also reading another message. \n\nFor Teams, users can simply switch from one chat to another and have meetings that are more efficient.\n\nGiven the legacy of the Microsoft apps along with being a large company, implementing the multi-window experience was a one-month project, while implementing multi-instance took the team two months to complete. The improved experiences and the positive customer reactions were better than the teams had hoped for!\n\nResults\n-------\n\nThrough their efforts, Microsoft has **enabled users to be more efficient and productive** on large screen devices. These investments led to **increased active users and retention,** and **positive customer feedback.** With the success they've seen for these apps, the Microsoft team will be continuing to evolve the user experience for all screens.\n\nGet started\n-----------\n\nLearn more about how you can get started with optimizing your app for [large screens](http://d.android.com/large-screens), and learn more about large screen [app quality](https://developer.android.com/docs/quality-guidelines/large-screens-app-quality)."]]
