Cannot resolve method 'show(android.support.v4.app.FragmentManager, java.lang.String)
To solve this, if you are using android.app.DialogFragment, then use getFragmentManager():
mDateButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { FragmentManager fm = getActivity().getFragmentManager(); DatePickerFragment dialog = new DatePickerFragment(); dialog.show(fm, DIALOG_DATE); } });to use getSupportFragmentManager(), must extend from: android.support.v4.app.DialogFragment.
check your import:
import android.support.v4.app.DialogFragment;
This solved the problem for me.
public void showDatePicker() { DialogFragment newFragment = new DatePickerFragment(); newFragment.show(getFragmentManager(),"datePicker"); }
