  Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR, 2013);   //设定年份
//      calendar.set(Calendar.MONTH, 10);   //设定月份,显示的比当前多一个月
        calendar.set(Calendar.DAY_OF_MONTH, 20);  //设定日期
        calendar.set(Calendar.HOUR_OF_DAY, 17);   //设定 小时
        calendar.set(Calendar.MINUTE, 30);     //设定分钟
        
//      calendar.add(Calendar.DATE, 7);  //下周的
//        calendar.add(Calendar.MONTH, 1);   //下个月
        
        Date date =  calendar.getTime();
        date.getTime();
        SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        mDateFormat.format(date);
        Log.d("test",  mDateFormat.format(date));
        

 

得到第二天的当前时间：

 

Date date = new Date(time);
    	int hours = date.getHours();
    	int minutes = date.getMinutes();
    	int second = date.getSeconds();
    	
    	SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
		Calendar calendar = Calendar.getInstance();
		calendar.add(Calendar.DATE, 1);
		String nextDayString = mDateFormat.format(calendar.getTime());
		String nextDayStringArray [] = nextDayString.split(" ");
		String nextDateString = nextDayStringArray[0]+" "+hours+":"+minutes + ":" + second;
		Date nextDate = null;
		try {
			nextDate = mDateFormat.parse(nextDateString);
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		Log.d("test", "time" + nextDate.getTime());

 long型 得到 具体时间

SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
			
String preTmp = mDateFormat.format(preDate);

 

SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");   
Date date = new Date(weekTime);

 得到时间格式：

 10:23:14 AM 11/09

 private String getTime() {
		Calendar calendar = Calendar.getInstance();
		Date date = calendar.getTime();
		long time = date.getTime();
		Date date2 = new Date(time);
		SimpleDateFormat mDateFormat = new SimpleDateFormat("hh:mm:ss aa MM/dd");
		mDateFormat.format(date2);
		return mDateFormat.format(date2);
	}

 

    获取手机的时间格式：

 

 ContentResolver cv = this.getContentResolver();

String  ddFormat = android.provider.Settings.System.getString(cv,
        android.provider.Settings.System.DATE_FORMAT);

        Log.d("test", "+++++++====" + ddFormat);
