    }

    class MarkBean {
        private String name;
        private String value;

        private String getName() {
            return name;
        }

        private void setName(String name) {
            this.name = name;
        }

            return value;
        }

        void setValue(String value) {
            this.value = value;
        }
    }

}

就是由原来简单的布局换成了一个RecyclerView去加载一个带有颜色的列表，看上去就好看了
