android - How can I use a `DatePickerDialog` in a FragmentActivity? -

i'm developing android application , have problem designing layouts:

i have code inside fragment:

datepickerdialog dialog =       datepickerdialog(getactivity(), mdatesetlistener, myear, mmonth, mday); 

and compiler error:

the method datepickerdialog(fragmentactivity, datepickerdialog.ondatesetlistener, int, int, int) undefined type userprofilefragment  userprofilefragment.java     

how can use datepickerdialog inside fragment?

by way, "parent" activity extends slidingfragmentactivity.

you missed new keyword

datepickerdialog dialog = new      datepickerdialog(getactivity(), mdatesetlistener, myear, mmonth, mday);
