Question

我正在使用这个BadgeView类在日历事件日期创建徽章。第一次运行它但是当下个月BadgeView类它给出stackoverflow错误.. 由此调用的badgeView类和在linearlayout上的徽章appy

badge = new BadgeView(context, event_dateview_layout);
                    badge.setText("" + eventno.size());
                    Log.d("aa", "eventno:" + eventno);
                    badge.show();
