Full screen DialogFragment

Question

I am trying to create a DialogFragment with a width of MATCH_PARENT so the dialog is nearly full screen (leaving the padding around the edges for the floating look). I have see

To have a full screen dialog, you need use

public class CustomDialogFragment extends DialogFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        // Inflate the layout to use as dialog or embedded fragment
        return inflater.inflate(R.layout.purchase_items, container, false);
    }


    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }
}

And to show this dialog:

CustomDialogFragment newFragment = new CustomDialogFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
// To make it fullscreen, use the 'content' root view as the container
// for the fragment, which is always the root view for the activity
fragmentManager.beginTransaction().add(android.R.id.content, newFragment).commit();

ATTENTION: You can't use following code to show the dialog, if not, the dialog will be shown in center of screen, not full screen.

//don't show dialog like this
newFragment.show(fragmentManager, "dialog");
