sheet = new SweetSheet(mRootView); CustomDelegate customDelegate = new CustomDelegate(true, CustomDelegate.AnimationType.DuangLayoutAnimation); View mSheetView = LayoutInflater.from(getActivity()).inflate(R.layout.disc_near_shop_bottom_sheet, null, false); customDelegate.setCustomView(mSheetView); sheet.setDelegate(customDelegate);
