Do not show again checkbox on a DialogFragment

Question

So the title explains it all. I have a dialogfragment that currently pops up and I want to add a do not show checkbox to it and then obviously implement that check and not show if it was checked. I know there is a .setSingleChoiceItems, but I am not entirely sure on what would be going in there as it isn't really an item I would add somewhere. But then again I could probably be wrong as I am just getting into Android development.

Dialogfragment java

public class WifivsDataDialog extends DialogFragment {


     @
     Override
     public Dialog onCreateDialog(Bundle savedInstanceState) {
         // Use the Builder class for convenient dialog construction
         AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
         builder.setMessage(R.string.dialog_box)
             .setPositiveButton(R.string.WiFi, new DialogInterface.OnClickListener() {
                 public void onClick(DialogInterface dialog, int id) {
                     // FIRE ZE MISSILES!

                 }
             })
             .setNegativeButton(R.string.Cell_Data, new DialogInterface.OnClickListener() {
                 public void onClick(DialogInterface dialog, int id) {
                     // User cancelled the dialog
                 }
             });
         // Create the AlertDialog object and return it
         return builder.create();
     }
 }

Here is the code calling it in my MainActivity.java

 WifivsDataDialog myDiag = new WifivsDataDialog();
    myDiag.show(getFragmentManager(), "dialog_layout");
    myDiag.setCancelable(false);

The DialogFragment class

    public class WifivsDataDialog extends DialogFragment implements View.OnClickListener {
    private CheckBox checkBox;
    private Button button1;
    private Button button2;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View mainView = inflater.inflate(R.layout.wifi_dialog, container);
        checkBox = (CheckBox) mainView.findViewById(R.id.checkBox);
        button1 = (Button) mainView.findViewById(R.id.button1);
        button2 = (Button) mainView.findViewById(R.id.button2);

        button1.setOnClickListener(this);
        button2.setOnClickListener(this);

        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
                // Store the isChecked to Preference here
                SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
                SharedPreferences.Editor editor = sharedPref.edit();
                editor.putBoolean("DONT_SHOW_DIALOG", isChecked);
                editor.commit();

            }
        });
        return mainView;
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.button1:
                // Do wifi stuff here
                break;
            case R.id.button2:
                // Do cellular stuff here
                break;
        }
    }
}

The Layout xml wifi_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:padding="20dp"
              android:layout_width="match_parent"
              android:layout_height="match_parent">

    <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Some information to be displayed to human"
            android:id="@+id/textView" android:textSize="30dp"/>
    <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Do now show this dialog again."
            android:id="@+id/checkBox"/>
    <LinearLayout
            android:orientation="horizontal"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" android:gravity="center">
        <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="WiFi"
                android:id="@+id/button1" android:layout_gravity="center_horizontal"/>
        <Button
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="CELL"
                android:id="@+id/button2"/>
    </LinearLayout>
</LinearLayout>

And on your Activity or where ever you display the dialog, check the preference set by user before displaying the dialog. Something like below.

SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
        boolean dontShowDialog = sharedPref.getBoolean("DONT_SHOW_DIALOG", false);
        if (!dontShowDialog) {
            new WifivsDataDialog().show(getFragmentManager(), "WiFi");
        }
