Disable dialog fragment up when keyboard show

Question

The pink one is a DialogFragment. When keyboard show, it was going up and overlap the toolbar. How can I make the dialog fragment stay the same and only the edittext go up.

I used SOFT_INPUT_ADJUST_PAN or SOFT_INPUT_ADJUST_RESIZE but the fragment still go up

SOFT_INPUT_ADJUST_NOTHING: both dialog and edit text stay the same but I want the edit text go up

Any help will be appreciated?

MainActivity.java:

public class HelloDialogFragment extends DialogFragment {


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.dialog_fragment, container, false);
        return v;
    }

    @Override
    public void onStart() {
        super.onStart();
        Dialog dialog = getDialog();
        if (dialog != null && dialog.getWindow() != null) {
            Window window = dialog.getWindow();
            TypedValue tv = new TypedValue();
            getContext().getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true);
            int actionBarHeight = getResources().getDimensionPixelSize(tv.resourceId);
            int statusBarHeight = (int) getResources().getDimension(R.dimen.status_bar_height);
            window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
            window.setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
                    WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
            window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            WindowManager.LayoutParams params = window.getAttributes();
            params.gravity = Gravity.LEFT | Gravity.TOP;
            params.x = 200 + 2 * Utils.dpToPx(8);
            params.y = statusBarHeight + actionBarHeight + Utils.dpToPx(8);
            params.width = Utils.screenWidth() / 3;
            params.height = Utils.screenHeight() - statusBarHeight - actionBarHeight - 2 * Utils.dpToPx(8);
            window.setAttributes(params);
            dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
        }
    }

    static class Utils {

        public static int screenWidth() {
            return Resources.getSystem().getDisplayMetrics().widthPixels;
        }

        public static int screenHeight() {
            return Resources.getSystem().getDisplayMetrics().heightPixels;
        }

        public static int dpToPx(int dp) {
            return (int) (dp * Resources.getSystem().getDisplayMetrics().density);
        }

    }

}

Finally I found a tricky to implement it First, make the Dialog fragment height match parent Second, add a transparent view at the top of the view (height equal to toolbar). So, when keyboard show, the dialog will be resize but doesn't move up and overlap toolbar
