如何修改Android系统默认时间

Posted 2023-04-30

参考技术A 1、 修改文件alps\frameworks\base\packages\SettingsProvider\res\values\defaults.xml，增加代码<string name="time_12_24" translatable="false">24</string>，红色标记表示24小时制，也可以改为12（12小时制）。2、修改文件alps\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java，找到函数loadSystemSettings ()，在函数中增加以下语句：loadStringSetting(stmt, Settings.System.TIME_12_24, R.string.time_12_24)即可。
