推荐答案

在运行Android 4+的平板电脑中，无法隐藏系统/导航栏.

In Tablets running Android 4+, it is not possible to hide the System / Navigation Bar.

来自文档(系统UI控件可见性部分):

SYSTEM_UI_FLAG_HIDE_NAVIGATION是一个新标志，它请求 导航栏完全隐藏.请注意，这仅适用于 某些手机​​使用的导航栏(它不会隐藏系统栏 在平板电脑上).

The SYSTEM_UI_FLAG_HIDE_NAVIGATION is a new flag that requests the navigation bar hide completely. Be aware that this works only for the navigation bar used by some handsets (it does not hide the system bar on tablets).

但是，您有时可以像在游戏和视频播放期间一样尝试调暗系统栏.

However, you could try to dim the system bar as done sometimes during gaming and video playback.

SYSTEM_UI_FLAG_LOW_PROFILE标志替换STATUS_BAR_HIDDEN 旗帜.设置后，此标志为系统启用低调"模式 栏或导航栏.导航按钮变暗，并且其中的其他元素 系统栏也会隐藏.启用它对于创建更多内容很有用 无需沉迷于系统导航按钮的沉浸式游戏.

The SYSTEM_UI_FLAG_LOW_PROFILE flag replaces the STATUS_BAR_HIDDEN flag. When set, this flag enables "low profile" mode for the system bar or navigation bar. Navigation buttons dim and other elements in the system bar also hide. Enabling this is useful for creating more immersive games without distraction for the system navigation buttons.
