导航栏和状态栏配置¶

本章节介绍如何隐藏或显示 Android 系统导航栏和状态栏。

命令行¶

通过 ADB 命令临时隐藏或显示状态栏和导航栏，重启设备后恢复为默认状态。

Rockchip Series / T527¶

# 隐藏状态栏
adb shell am broadcast -a android.intent.action.HIDE_STATUSBAR_BAR

# 显示状态栏
adb shell am broadcast -a android.intent.action.SHOW_STATUSBAR_BAR

# 隐藏导航栏
adb shell am broadcast -a android.intent.action.HIDE_NAVIGATION_BAR

# 显示导航栏
adb shell am broadcast -a android.intent.action.SHOW_NAVIGATION_BAR

A133¶

通过系统属性设置，重启设备后生效：

adb shell setprop persist.sys.ban_sb true
adb shell setprop persist.sys.ban_nb true
adb reboot

A733¶

通过全局设置控制，设置后立即生效，无需重启设备：

# 隐藏状态栏
adb shell settings put global status_bar_enabled 0

# 显示状态栏
adb shell settings put global status_bar_enabled 1

# 隐藏导航栏
adb shell settings put global navigation_bar_enabled 0

# 显示导航栏
adb shell settings put global navigation_bar_enabled 1

APP 例程¶

从网盘中获取状态栏和导航栏测试 APP 例程。

SDK 源码修改¶

通过修改 SystemUI 源码实现默认隐藏或禁用状态栏和导航栏。

默认隐藏状态栏¶

修改 CentralSurfacesImpl.java，调用 hideStatusBar() 方法：

--- a/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/CentralSurfacesImpl.java
+++ b/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/CentralSurfacesImpl.java

         if (mWallpaperSupported) {
             // Make sure we always have the most current wallpaper info.

默认禁止状态栏下拉¶

修改 CommandQueue.java，使 panelsEnabled() 方法返回 false：

+++ b/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/CommandQueue.java

     }

默认隐藏导航栏¶

修改 CentralSurfacesImpl.java，调用 hideNavigation() 方法：

--- a/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/CentralSurfacesImpl.java
+++ b/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/CentralSurfacesImpl.java

             // Make sure we always have the most current wallpaper info.

Overlay 配置¶

通过修改 overlay 配置文件实现开机默认状态。

默认手势导航¶

RK 平台修改 config.xml 中的 config_navBarInteractionMode 启用手势导航：

--- a/device/rockchip/rk356x/overlay/frameworks/base/core/res/res/values/config.xml
+++ b/device/rockchip/rk356x/overlay/frameworks/base/core/res/res/values/config.xml

默认隐藏状态栏 / 导航栏¶

A733 / T527 修改 SettingsProvider 的 overlay 配置文件，使状态栏和导航栏在开机后默认隐藏：

--- a/.../SettingsProvider/res/values/defaults.xml
+++ b/.../SettingsProvider/res/values/defaults.xml
+
+    <bool name="def_navigation_bar_enabled">false</bool>
+    <bool name="def_status_bar_enabled">false</bool>
