attrs.xml添加属性

使用

/** *  设置值 * @param values * array[0] 开始时间 * array[1] 结束时间 * array[2] 颜色值 */void setValues(List values)void setParentViewGroup(ViewGroup parentViewGroup)/** * 添加选中监听 */scStatis.setOnSelectedChanged(new SleepCartogramView.OnSelectedChanged() {            @Override            public void onChanged(int position) {            }        });
