我试图弄清楚如何在活动创建期间将焦点设置在 CalendarView 中的特定日期上，该日期是已知的并存储在一个单独的字符串变量中，可以说theDate并且具有“dd/mm/yyyy知道这一点”的格式，我可以让日历专注于具体日期？
Assume calendar view is mCalendarViewin this case.
假设日历视图mCalendarView在这种情况下。

Try this method in CalendarView: http://developer.android.com/reference/android/widget/CalendarView.html#setDate(long)
在 CalendarView 中试试这个方法：http: //developer.android.com/reference/android/widget/CalendarView.html#setDate(long)
As for converting between the dd/mm/yyyy format to milliseconds format, I recommend that you store the date in millisecond format and only convert to the dd/mm/yyyy format when displaying the date. If you have to use the dd/mm/yyyy format, though, I would try the following:
至于在dd/mm/yyyy格式和毫秒格式之间的转换，我建议你以毫秒格式存储日期，显示日期时只转换为dd/mm/yyyy格式。但是，如果您必须使用 dd/mm/yyyy 格式，我会尝试以下操作：
String date = "22/3/2014";
String parts[] = date.split("/");
int day = Integer.parseInt(parts[0]);
int month = Integer.parseInt(parts[1]);
int year = Integer.parseInt(parts[2]);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, month);
calendar.set(Calendar.DAY_OF_MONTH, day);
long milliTime = calendar.getTimeInMillis();
And now set the selected date in the calendar view by doing
现在通过执行在日历视图中设置选定的日期
mCalendarView.setDate (milliTime, true, true);

this works on me :)
这对我有用:)
String selectedDate = "30/09/2016";
mCalendarView.setDate(new SimpleDateFormat("dd/MM/yyyy").parse(selectedDate).getTime(), true, true);
