安卓StepView事件进度条的简单实现

需求
1.竖向展示事件列表
2.每个事件包含详情内容时可进行展开折叠
3.默认展开最后一级别有内容的列表

既然说简单实现。那么用RecyclerView实现吧

1.item布局，这里可以把一个个item分割为以下部分

---

我们这里可以利用recyclerview默认不带分割线的特点，最左侧的进度线就分割成两条线跟一个图片。右边展开折叠只是显示隐藏布局。展开的布局比较简单就是一个文本加上一个recyclerview展示图文。

看一下布局代码吧

布局OK那么接下来就是实体类的设计啦。这个得根据自己的业务处理咯

public static class RDataBean extends BaseEntity {        /**         * im_feedback_dispose_id : 1         * im_feedback_id : 3         * user_id : 27233218         * group_sys_name : 小队1         * duty_name :         * dispose_content : blend咯lol         * imgs : ["imgs/1511775047258.png"]         * submit_status : 0         * inittime : 1511775047         * dispose_status : 1         * user_name : 李基旺         */        private String im_feedback_dispose_id;        private String im_feedback_id;        private String user_id;        private String group_sys_name;        private String duty_name;        private String dispose_content;        private String submit_status;        private String inittime;        private String dispose_status;        private String user_name;        private boolean expand = false;//判断是否展开        private String telphone;//: "",        private String user_sf;//: "",        private String user_head_img;//: ""        private String nameDuty;        public String getNameDuty() {            if(!TextUtils.isEmpty(duty_name)&&!TextUtils.isEmpty(user_name)){                return "--"+user_name + "(" + duty_name + ")";            }else {                if(TextUtils.isEmpty(user_name)){                    return "";                }else {                    return "--"+user_name;                }            }        }        public void setNameDuty(String nameDuty) {            this.nameDuty = nameDuty;        }        public String getTelphone() {            return telphone;        }        public void setTelphone(String telphone) {            this.telphone = telphone;        }        public String getUser_sf() {            return user_sf;        }        public void setUser_sf(String user_sf) {            this.user_sf = user_sf;        }        public String getUser_head_img() {            return user_head_img;        }        public void setUser_head_img(String user_head_img) {            this.user_head_img = user_head_img;        }        public boolean isExpand() {            return expand;        }        public void setExpand(boolean expand) {            this.expand = expand;        }        private List<String> imgs;        public String getIm_feedback_dispose_id() {            return im_feedback_dispose_id;        }        public void setIm_feedback_dispose_id(String im_feedback_dispose_id) {            this.im_feedback_dispose_id = im_feedback_dispose_id;        }        public String getIm_feedback_id() {            return im_feedback_id;        }        public void setIm_feedback_id(String im_feedback_id) {            this.im_feedback_id = im_feedback_id;        }        public String getUser_id() {            return user_id;        }        public void setUser_id(String user_id) {            this.user_id = user_id;        }        public String getGroup_sys_name() {            return group_sys_name;        }        public void setGroup_sys_name(String group_sys_name) {            this.group_sys_name = group_sys_name;        }        public String getDuty_name() {            return duty_name;        }        public void setDuty_name(String duty_name) {            this.duty_name = duty_name;        }        public String getDispose_content() {            return dispose_content;        }        public void setDispose_content(String dispose_content) {            this.dispose_content = dispose_content;        }        public String getSubmit_status() {            return submit_status;        }        public void setSubmit_status(String submit_status) {            this.submit_status = submit_status;        }        public String getInittime() {            return inittime;        }        public void setInittime(String inittime) {            this.inittime = inittime;        }        public String getDispose_status() {            return dispose_status;        }        public void setDispose_status(String dispose_status) {            this.dispose_status = dispose_status;        }        public String getUser_name() {            return user_name;        }        public void setUser_name(String user_name) {            this.user_name = user_name;        }        public List<String> getImgs() {            return imgs;        }        public void setImgs(List<String> imgs) {            this.imgs = imgs;        }    }

给个思路吧，每个item都有三条进度线，我们在适配器中主要的工作就是判断这个线的颜色跟是否隐藏。然后就是点击事件，点击事件的话这里用了第三的开源库适配器写法相对简单。CymChad:BaseRecyclerViewAdapterHelper
