问题描述

我试图找出如何设置一个焦点上的活动创建过程中CalendarView特定日期，日期是已知的，储存在一个单独的字符串变量，可以说 theDate 并具有 DD / MM / YYYY 知道了这一点，我可以让日历专注于一个特定的日期？

I'm trying to figure out how to set a focus on a specific date in CalendarView during activity creation, The date is known and stored in a separate string variable, lets say theDate and has format of dd/mm/yyyy Knowing this, can I make calendar focus on a specific date?

假设日历视图是 mCalendarView 在这种情况下。

Assume calendar view is mCalendarView in this case.

推荐答案

尝试在CalendarView此方法：
的http://developer.android.com/reference/android/widget/CalendarView.html#setDate(long)

Try this method in CalendarView: http://developer.android.com/reference/android/widget/CalendarView.html#setDate(long)

对于DD / MM / YYYY格式之间进行转换，以毫秒为单位的格式，我建议你存储的日期格式毫秒，只显示日期时转换为DD / MM / YYYY格式。如果必须使用dd / mm / yyyy格式，不过，我会尝试以下方法：

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:

    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();

和现在做设置日历视图中选定日期

And now set the selected date in the calendar view by doing

    mCalendarView.setDate (milliTime, true, true);
