问题 I am new to Android programming. Please help. I am using Fragment that creates Material design DatePickerDialog on click of EditText . Trouble is it is set to current date (set by me).

I managed to do that via a thread, but in this case it only waits the amount of time indicated, before attaching the second fragment, and in case the first fragment isn't

问题 I have 3 fragments that are managed by an FragmentPagerAdapter, set to a viewPager.
