How to set a full-screen dialog with a dialog fragment

Question

I am doing a fullscreen dialog with a snippet of dialogue. I have successfully shown the dialog, but the problem is its width and height. It cannot display full screen size. I want to set the width and height with the accumulation of the full screen size, for example Activity. Please tell me how to set the width and height of the dialog in order to copy it to full screen size.

CustomeDialogFramgnet:

public class CustomDialogFragment extends DialogFragment {
    /** The system calls this to get the DialogFragment layout, regardless
     of whether it being displayed as a dialog or an embedded fragment. */
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout to use as dialog or embedded fragment
        View rootView = inflater.inflate(R.layout.item_fragment, null, false);

        Toolbar toolbar = (Toolbar) rootView.findViewById(R.id.toolbar);
        toolbar.setTitle("Dialog title");

        ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);

        ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
        if (actionBar != null) {
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setHomeAsUpIndicator(android.R.drawable.ic_menu_close_clear_cancel);
        }

        return rootView;
    }

    /** The system calls this only when creating the layout in a dialog. */
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // The only reason you might override this method when using onCreateView() is
        // to modify any dialog characteristics. For example, the dialog includes a
        // title by default, but your custom layout might not need it. So here you can
        // remove the dialog title, but you must call the superclass to get the Dialog.
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        return dialog;
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        menu.clear();
        getActivity().getMenuInflater().inflate(R.menu.alert_dialog_input, menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();

        if (id == R.id.action_save) {
            // handle confirmation button click here
            return true;
        } else if (id == android.R.id.home) {
            // handle close button click here
            dismiss();
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

    <item name="colorAccent">@color/colorAccent</item>

    <item name="android:paddingRight">0dp</item>
    <item name="android:paddingLeft">0dp</item>
    <item name="android:layout_width">match_parent</item>
    <item name="android:windowNoTitle">true</item>
</style>
