如何在DatePicker中设置当前日期？

I need to be able to choose date and time in my application It should either be done by using a dialog, or starting a new intent.

我需要能够在我的应用程序中选择日期和时间它应该通过使用对话框或启动新的意图来完成。

The way I have done it now, is that I have started a new intent, since I need to set both date and time.

我现在的方式是，我已经开始了新的意图，因为我需要设置日期和时间。

My problem is that I need to set the current date on the Datepicker (This is possible with the Timepicker using setCurrentHour and setCurrentMinute) onCreate, and set that as a lower boundary.

我的问题是我需要在Datepicker上设置当前日期（这可以通过使用setCurrentHour和setCurrentMinute的Timepicker）onCreate，并将其设置为下边界。

I can't find any functions in the Android API for doing this with the DatePicker.

我在Android API中找不到使用DatePicker执行此操作的任何功能。

Anyone have a suggestion to solve this problem?

有人建议解决这个问题吗？

Thanks in advance!

提前致谢！

Edit: Important: The DatePicker and TimePicker must be in the same dialog/intent

Straight to code

直接编码

Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH);
int mDay = c.get(Calendar.DAY_OF_MONTH);

DatePickerDialog dialog =
    new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
dialog.show();

#2

Try this:

尝试这个：

Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);     

// set current date into datepicker
datepicker.init(year, month, day, null);

#3

If you are simply looking for the equivalent of setCurrentHour() and setCurrentMinute() on TimePicker, but on DatePicker - see updateDate (int year, int month, int dayOfMonth) on DatePicker.

如果您只是在TimePicker上查找等效的setCurrentHour（）和setCurrentMinute（），但是在DatePicker上 - 请参阅DatePicker上的updateDate（int year，int month，int dayOfMonth）。

DatePicker mDatePicker = (DatePicker) findViewById(R.id.datePicker);
mDatePicker.updateDate(1994, 6, 12);
// Sets date displayed on DatePicker to 12th June 1994

#4

You can query the current date through the Calendar class.

您可以通过Calendar类查询当前日期。

Calendar now = Calendar.getInstance();
now.get(Calendar.WHATDOYOUNEED);

Feed it's get() method with different parameters to customize your query.

使用不同的参数提供它的get（）方法来自定义查询。

Refer to:

参考：

    // get the current date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    // display the current date (this method is below)
