I was used to the datepicker from android 2.2 and I'm not familiar with calendarview and can't find much about it either. Does anyone know a solution for this?

推荐答案

好了，所以这里是如何做到这一点。当您炒掉calendarview活动或活动内的calendarview它设置日期为当前日期（今天的意思）。为了得到这个当前日期只使用日历由Java API提供的对象，将会在下面这个日期例如：

Okay so here is how to do this. When you fire your calendarview activity or a calendarview inside your activity it sets the date to the current date(meaning today). To get this current date just use the Calendar object provided by the java api to get this date example below:

Calendar date = Calendar.getInstance();
// for your date format use
SimpleDateFormat sdf = new SimpleDateFormat("yy-MM-dd");
// set a string to format your current date
String curDate = sdf.format(date.getTime());
// print the date in your log cat
Log.d("CUR_DATE", curDate);

要得到一个日期改变，你必须这样做。

to get a date changed you must do this

CalendarView myCalendar = (CalendarView) findViewById(R.id.myCalenderid);

myCalendar.setOnDateChangeListener(myCalendarListener);

OnDateChangeListener myCalendarListener = new OnDateChangeListener(){

public void onSelectedDayChange(CalendarView view, int year, int month, int day){

   // add one because month starts at 0
   month = month + 1;
   // output to log cat **not sure how to format year to two places here**
   String newDate = year+"-"+month+"-"+day;
   Log.d("NEW_DATE", newDate);
}
}
