Android(安卓)获取系统时间

[java] view plaincopyprint?

import java.text.SimpleDateFormat;

SimpleDateFormat formatter = new SimpleDateFormat ("yyyy年MM月dd日 HH:mm:ss ");

Date curDate = new Date(System.currentTimeMillis());//获取当前时间

String str = formatter.format(curDate);

可以获取当前的年月时分,也可以分开写:

[java] view plaincopyprint?

SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

String date = sDateFormat.format(new java.util.Date());

如果想获取当前的年月,则可以这样写(只获取时间或秒种一样):

Java代码

[java] view plaincopyprint?

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM");

String date=sdf.format(new java.util.Date());

当然还有就是可以指定时区的时间(待):

[java] view plaincopyprint?

df=DateFormat.getDateTimeInstance(DateFormat.FULL,DateFormat.FULL,Locale.CHINA);

System.out.println(df.format(new Date()));

如何获取Android系统时间是24小时制还是12小时制

[java] view plaincopyprint?

ContentResolver cv = this.getContentResolver();

String strTimeFormat = android.provider.Settings.System.getString(cv,

android.provider.Settings.System.TIME_12_24);

if(strTimeFormat.equals("24"))

{

Log.i("activity","24");

}

[java] view plaincopyprint?

Calendar c = Calendar.getInstance();

取得系统日期:year = c.get(Calendar.YEAR)

month = c.grt(Calendar.MONTH)

day = c.get(Calendar.DAY_OF_MONTH)

取得系统时间：hour = c.get(Calendar.HOUR_OF_DAY);

minute = c.get(Calendar.MINUTE)

利用Calendar获取

[java] view plaincopyprint?

Calendar c = Calendar.getInstance();

取得系统日期:year = c.get(Calendar.YEAR)

month = c.grt(Calendar.MONTH)

day = c.get(Calendar.DAY_OF_MONTH)

取得系统时间：hour = c.get(Calendar.HOUR_OF_DAY);

minute = c.get(Calendar.MINUTE)

Calendar c = Calendar.getInstance();

取得系统日期:year = c.get(Calendar.YEAR)

month = c.grt(Calendar.MONTH)

day = c.get(Calendar.DAY_OF_MONTH)

取得系统时间：hour = c.get(Calendar.HOUR_OF_DAY);

minute = c.get(Calendar.MINUTE)

利用Time获取

[java] view plaincopyprint?

Time t=new Time(); // or Time t=new Time("GMT+8"); 加上Time Zone资料。

t.setToNow(); // 取得系统时间。

int year = t.year;

int month = t.month;

int date = t.monthDay;

int hour = t.hour; // 0-23

int minute = t.minute;

int second = t.second;

唯一不足是取出时间只有24小时模式.
