什么是导航栏与状态栏

最上面是状态栏 StatusBar
最下面是导航栏 NavagationBar

一、隐藏导航栏

方法一，修改资源文件代码

frameworks/base/core/res/res/values/dimens.xml

<dimen name="navigation_bar_height">48dp</dimen><!-- Height of the bottom navigation bar in portrait; often the same as @dimen/navigation_bar_height --><dimen name="navigation_bar_height_landscape">48dp</dimen><!-- Width of the navigation bar when it is placed vertically on the screen -->

将高度 48 改成 0

方法二，通过系统 property 来控制

路径 device/rockchip/rk3399/system.prop

qemu.hw.mainkeys=1

代码调用
rk3399/frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java

mHasNavigationBar = res.getBoolean(com.android.internal.R.bool.config_showNavigationBar);// Allow a system property to override this. Used by the emulator.// See also hasNavigationBar().String navBarOverride = SystemProperties.get("qemu.hw.mainkeys");if ("1".equals(navBarOverride)) {    mHasNavigationBar = false;} else if ("0".equals(navBarOverride)) {    mHasNavigationBar = true;}

二、隐藏状态栏

修改资源文件代码

frameworks/base/core/res/res/values/dimens.xml

<dimen name="status_bar_height">24dp</dimen><!-- Height of the bottom navigation / system bar. -->

将高度 24 改成 0
