我需要以编程方式从Android设置日期/时间,但我没有成功! 我上面有这三个来源:
源代码1
AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);
alarm.setTime(1330082817000);
AndroidManifest:
<uses-permission android:name="android.permission.SET_TIME" />
<uses-permission android:name="android.permission.SET_TIME_ZONE" />
例外:
Service fatal error : Unable to start activity ComponentInfo{br.com.tdta.service/br.com.tdta.service.Service}: java.lang.SecurityException: setTime: Neither user 10038 nor current process has android.permission.SET_TIME.
java.lang.RuntimeException: Unable to start activity ComponentInfo{br.com.tdta.service/br.com.tdta.service.Service}: java.lang.SecurityException: setTime: Neither user 10038 nor current process has android.permission.SET_TIME.

源代码2
boolean itsWork = SystemClock.setCurrentTimeMillis(1330082817000);
System.out.println(itsWork);
清单:
<uses-permission android:name="android.permission.SET_TIME" />
<uses-permission android:name="android.permission.SET_TIME_ZONE" />
其工作值:
false

源代码3
SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd.hhmmss");
String data = format.format(new Date(1330082817000));
try {
Runtime.getRuntime().exec("date -s " + data);
} catch (IOException e) {
}
我做错了什么?
提前致谢!
答案 0 :(得分:14)
用户应用程序无权更改设备时间。请通过following post中的cashbash以替代选项阅读答案。
在此处复制以供快速参考:
根据this thread,用户应用无法设置时间,无论我们提供的权限如何。相反,最好的方法是让用户手动设置时间。我们将使用:
startActivity(new Intent(android.provider.Settings.ACTION_DATE_SETTINGS));
不幸的是,没有办法将它们直接链接到时间设置(这样可以再次点击它们)。通过使用ellapsedRealtime
,我们可以确保用户正确设置时间。
