Try this. It works for me.

@Override
public void setupDialog(Dialog dialog, int style) {
    super.setupDialog(dialog, style);
    View inflatedView = View.inflate(getContext(), R.layout.fragment_coupon, null);
    dialog.setContentView(inflatedView);


    CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) ((View) inflatedView.getParent()).getLayoutParams();
    CoordinatorLayout.Behavior behavior = params.getBehavior();

    if (behavior != null && behavior instanceof BottomSheetBehavior) {
        ((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
    }

    View parent = (View) inflatedView.getParent();
    parent.setFitsSystemWindows(true);
    BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(parent);
    inflatedView.measure(0, 0);
    DisplayMetrics displaymetrics = new DisplayMetrics();        getActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    int screenHeight = displaymetrics.heightPixels;
    bottomSheetBehavior.setPeekHeight(screenHeight);

    if (params.getBehavior() instanceof BottomSheetBehavior) {
        ((BottomSheetBehavior)params.getBehavior()).setBottomSheetCallback(mBottomSheetBehaviorCallback);
    }

    params.height = screenHeight;
    parent.setLayoutParams(params);
}
