推荐答案

使用 "status_bar_height" 查询状态栏的高度，即导航栏上方的部分(包含通知和系统图标，见此处).您必须使用 "navigation_bar_height"(参见此处).

With "status_bar_height" you are querying the height of the status bar, which is the part above the navigation bar (the bit containing the notification and system icons, see here). You'll have to use "navigation_bar_height" (see here).

免责声明:虽然从字面上回答您的问题，但这很可能与您想要的有所不同.Android 导航栏通常位于底部，包含 back、home 和 overview 按钮(见这里).

Disclaimer: While literally answering your question, this might well be something different from what you want. The Android Navigation Bar is the bar that's usually at the bottom, containing the back, home and overview buttons (see here).

在 Android 上，您可以使用 GetBarHeight(IPlatformElementConfiguration<Android,NavigationPage>) 扩展(

On Android you have the possibility to get the height of the bar with the GetBarHeight(IPlatformElementConfiguration<Android,NavigationPage>) extension (see here), which can be used like

On<Xamarin.Forms.PlatformConfiguration.Android>.GetBarHeight()

来自导航页面背后的代码.

from the code behind of your navigation page.
