控制系統 UI 的顯示設定
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
圖 1 系統列，包括 [1] 狀態列和 [2] 導覽列。
系統列是專門用來顯示通知、裝置狀態通訊和裝置導覽的畫面區域。系統列 (由狀態和導覽列組成，如圖 1 所示) 通常會與應用程式同時顯示。顯示沉浸式內容 (例如電影或圖片) 的應用程式可以暫時調暗系統列圖示，減少干擾體驗；或者為了提供完全沉浸式的體驗，系統列會暫時隱藏長條。
如果您熟悉 Android 設計指南，請務必瞭解依照標準 Android UI 指南和使用模式設計應用程式的重要性。修改系統列前，您應審慎考量使用者的需求和期望，因為他們可讓使用者以標準的方式瀏覽裝置及查看狀態。
這個類別說明如何在 Android 版本的不同版本中調暗或隱藏系統資訊列，以提供沉浸式使用者體驗，同時仍能輕鬆存取系統列。

Typically the system bars (which consist of the status\nand navigation bars, as shown in figure 1) are displayed\nconcurrently with your app. Apps that display immersive content, such as movies or images,\ncan temporarily dim the system bar icons for a less distracting experience,\nor temporarily hide the bars for a fully immersive experience.\n\nIf you're familiar with the [Android Design\nGuide](/design), you know the importance of designing your apps to conform to standard Android UI\nguidelines and usage patterns. You should carefully consider your users'\nneeds and expectations before modifying the system bars, since they give users a\nstandard way of navigating a device and viewing its status. \n\nThis class describes how to dim or hide system bars across different versions of Android\nto create an immersive user experience, while still preserving easy access to the system\nbars.\n\nLessons\n-------\n\n\n**[Dimming the System Bars](/training/system-ui/dim)**\n:\n Learn how to dim the status and navigation bars.
