提问by GuyWhoReadsStockoverflow
Currently I am using code below and I can get current date to be dispalyed in Text field. However I have no idea how to display selected date.
目前我正在使用下面的代码，我可以在文本字段中显示当前日期。但是我不知道如何显示选定的日期。
I also used DatePicker and it displays selected date fine, however I would prefer CalendarView. Thanks
我还使用了 DatePicker，它可以很好地显示所选日期，但是我更喜欢 CalendarView。谢谢
Calendar c = Calendar.getInstance();
SimpleDateFormat ss = new SimpleDateFormat("dd-MM-yyyy");
Date date = new Date();
String currentdate= ss.format(date);
TextView editText = (TextView) this.findViewById(R.id.textfield1);
editText.setText(currentdate);

in onCreate :
在 onCreate 中：
CalendarView v = new CalendarView( this );
v.setOnDateChangeListener( new CalendarView.OnDateChangeListener() {
public void onSelectedDayChange(CalendarView view, int year, int month, int dayOfMonth) {
this.calendar = new GregorianCalendar( year, month, dayOfMonth );
}//met
});

CalendarView view = new CalendarView(this);
setContentView(view);
view.setOnDateChangeListener(new OnDateChangeListener() {
@Override
public void onSelectedDayChange(CalendarView arg0, int year, int month,
int date) {
Toast.makeText(getApplicationContext(),date+ "/"+month+"/"+year,4000).show();
}
});
This will display the user selected date.
这将显示用户选择的日期。

Calendar c = Calendar.getInstance();
Calendaris different from CalendarView. CalendarViewis a descendant of Viewso it has many event handlers, like an onClickListener. Perhaps this is what you are trying to find?
Calendar与CalendarView不同。CalendarView是 的后代，View因此它有许多事件处理程序，例如onClickListener。也许这就是你想要找到的？
