Wrong 1st argument type. required "android.app.fragment"

I have a problem when using DialogFragment 

DialogFragment dialog = new DateDialog(this);
dialog.setTargetFragment(this,1);
dialog.show(getFragmentManager(), "tag");

Where this caused the error. my class extends FragmentActivity.

enter image description here

I'm following this answer, but so far, cannot apply on my code. what do i do wrong ?

This is my class :

import android.app.AlertDialog;
import android.app.DatePickerDialog.OnDateSetListener;
import android.app.Dialog;
import android.app.DialogFragment;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.RadioGroup;
import android.support.v4.app.Fragment;

public class RegisterActivity extends FragmentActivity implements OnDateSetListener
{

}

Be sure you are using the correct DialogFragment:

http://developer.android.com/reference/android/app/DialogFragment.html

   ↳    android.app.Fragment
       ↳    android.app.DialogFragment

versus

   ↳    android.support.v4.app.Fragment
       ↳    android.support.v4.app.DialogFragment

It's easy to import the wrong class. Just look at which version of FragmentActivity you are using and pick the corresponding DialogFragment.
