                        if (mArrWeightList != null && mArrWeightList.size() > 0) {
                            Log.print("mIsDialogueClick:::mArrWeightList::: " + mIsDialogueClick);
                            if (!mIsDialogueClick) {
                                mIsDialogueClick = true;
                                showDialogBox(mDialogFor, txtWeight, getString(R.string.alert_select_weight));
