Android获得时间总结

Java 代码

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); 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代码

SimpleDateFormat sDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); String date = sDateFormat.format(new java.util.Date()); 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

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM"); String date=sdf.format(new java.util.Date()); 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):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

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");}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 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

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; // 0-23int minute = t.minute;int second = t.second;

唯一不足是取出时间只有24小时模式.
