android - 通过 adb shell 设置系统时间格式

Question

我正在尝试编写一个简单的表单实用程序来配置附加的 android 设备。我需要执行的一项操作是更改系统时区、时间和时间格式。

我通过以下方式设置系统时区：

adb shell setprop persist.sys.timezone "America/Chicago"

通过更改时间

adb shell date -s YYYYMMDD.HHmmss

现在我需要设置设备的 12/24 小时格式，但我不知道该怎么做。它需要通过 adb 来完成。任何帮助表示赞赏，谢谢！

Answer 1

IF "%time:~0,1%"==" " (
    SET mynow=%date:~-4,4%%date:~-10,2%%date:~-7,2%.0%time:~1,1%%time:~3,2%%time:~6,2%
) ELSE (
    set mynow=%date:~-4,4%%date:~-10,2%%date:~-7,2%.%time:~0,2%%time:~3,2%%time:~6,2%
)


REM sourced from:
REM http://developer.android.com/reference/android/provider/Settings.System.html

REM STILL NEED
REM font scale = 1.25  (display -> font size = extra large)
REM screen lock = none (security -> screen lock)
REM scheduled power off 10:30pm daily  (scheduled power on & off


REM allow apps from unknown sources (settings-> developer options)
adb shell settings put secure install_non_market_apps 1

REM ... (settings-> developer options)
adb shell settings put global stay_on_while_plugged_in 3

REM display off after 30 minutes (settings-> display)
adb shell settings put system screen_off_timeout 1800000

REM display Font Scale X-Large (settings-> display)
REM write setting not working, read setting works fine
REM adb shell settings put system font_scale 1.25


REM set default rotation state to horizontal
adb shell settings put system user_rotation 0

REM use 12 hour format (settings->date & time)
adb shell settings put system time_12_24 12

REM Automatic date & time = use network provided (settings->date & time)
REM adb shell settings put global auto_time 1
REM Automatic date & time = OFF (settings->date & time)
adb shell settings put global auto_time 0

REM Automatic time zone = use network provided time-zone (settings->date & time)
REM adb shell settings put global auto_time_zone 1
REM Automatic time zone = OFF (settings->date & time)
adb shell settings put global auto_time_zone 0


REM set Date & Time
adb shell su 0 date -s %mynow%

启用 24 小时时间格式的命令是：

adb shell settings put system time_12_24 24
