需求
1.豎向展示事件列表
2.每個事件包含詳情內(nèi)容時可進行展開折疊
3.默認展開最后一級別有內(nèi)容的列表

既然說簡單實現(xiàn)。那么用RecyclerView實現(xiàn)吧

1.item布局，這里可以把一個個item分割為以下部分

---

我們這里可以利用recyclerview默認不帶分割線的特點，最左側(cè)的進度線就分割成兩條線跟一個圖片。右邊展開折疊只是顯示隱藏布局。展開的布局比較簡單就是一個文本加上一個recyclerview展示圖文。

看一下布局代碼吧

布局OK那么接下來就是實體類的設(shè)計啦。這個得根據(jù)自己的業(yè)務(wù)處理咯

public static class RDataBean extends BaseEntity {/*** im_feedback_dispose_id : 1* im_feedback_id : 3* user_id : 27233218* group_sys_name : 小隊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;//判斷是否展開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;}}

給個思路吧，每個item都有三條進度線，我們在適配器中主要的工作就是判斷這個線的顏色跟是否隱藏。然后就是點擊事件，點擊事件的話這里用了第三的開源庫適配器寫法相對簡單。CymChad:BaseRecyclerViewAdapterHelper
