How do you get a DatePicker from a DatePickerDialog?

android, datepicker, datepickerdialog

Solution

Despite that getter method only being available in Honeycomb and above (as dmon correctly pointed out), you can still fairly easily get access to the `DatePicker` object encapsulated by the `DatePickerDialog` using reflection. It'll look something like this:

DatePickerDialog dialog = ... // create dialog
Field mDatePickerField = dialog.getClass().getDeclaredField("mDatePicker");
mDatePickerField.setAccessible(true);
DatePicker mDatePickerInstance = (DatePicker) mDatePickerField.get(dialog);

From this point on, you have a reference to the internal `DatePicker` object and you should be able to change it to your own liking. Please do beware of any obvious typos, as I entered this directly into the browser.

Problem

I have a activity that is popping up a android.app.DatePickerDialog. ``` DatePickerDialog dialog = new DatePickerDialog(this, startDateSetListener, start_cal.get(Calendar.YEAR), start_cal.get(Calendar.MONTH), start_cal.get(Calendar.DATE)); ``` I want to get at the DatePicker View from the DatePickerDialog so that I can set the min and max dates. The API reference says that there is a method getDatePicker and that has been there since API 1 but it is invalid, my ide doesn't like it. ``` DatePicker picker = dialog.getDatePicker(); ``` "The method getDatePicker() is undefined for the type DatePickerDialog" Any one know what API was the method created in or how I can get to the DatePicker to edit min/max dates? I am using API 7, Platform 2.1.
