Cannot Resolve Method 'show(android.support.v4.app.fragmentmanager, Java.lang.string)

For some reason when I try to show a Dialog I get an error from dialog.show(fm, DIALOG_DATE); saying Cannot resolve method 'show(android.support.v4.app.FragmentManager, java.lang.

Solution 1:

To solve this, if you are using android.app.DialogFragment, then use getFragmentManager():

mDateButton.setOnClickListener(newView.OnClickListener() {
        publicvoidonClick(View v) {
            FragmentManagerfm= getActivity().getFragmentManager();
            DatePickerFragmentdialog=newDatePickerFragment();
            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;

Solution 2:

This solved the problem for me.

publicvoidshowDatePicker() {
        DialogFragment newFragment = new DatePickerFragment();
        newFragment.show(getFragmentManager(),"datePicker");
    }
