阅读更多关于 DatePickerDialog OK button not getting the selected date

问题 I have a simple DatePickerDialog that opens when an EditText is opened. After choosing a date and pressing OK, it should be displayed at the same EditText . It works fine if I only use the default dialog where it creates only one button - OK. I added a Cancel button, the problem is that it only gets the current date.

问题 In my app I have a date saved in a remote database that I want the date picker to be set to. I've researched and only found examples of setting the datepicker today's date via Calender java util. Example: final Calendar c = Calendar.getInstance(); year = c.get(Calendar.YEAR); month = c.get(Calendar.MONTH); day = c.get(Calendar.DAY_OF_MONTH); How can I use the Calendar to display my date from the database and not today's date? Do you have any suggestions or examples I can follow? Update: After
