Android获得时间总结

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:

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):

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()));

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)

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;
