然后是主要實現代碼：

相關數據結構（模擬）

CommentsBean

public class CommentsBean implements Serializable {
 private int commentsId;
 private String content;
 private UserBean replyUser; // 回復人信息
 private UserBean commentsUser; // 評論人信息

 public int getCommentsId() {
  return commentsId;
 }

 public void setCommentsId(int commentsId) {
  this.commentsId = commentsId;
 }

 public String getContent() {
  return content;
 }

 public void setContent(String content) {
  this.content = content;
 }

 public UserBean getReplyUser() {
  return replyUser;
 }

 public void setReplyUser(UserBean replyUser) {
  this.replyUser = replyUser;
 }

 public UserBean getCommentsUser() {
  return commentsUser;
 }

 public void setCommentsUser(UserBean commentsUser) {
  this.commentsUser = commentsUser;
 }
}

UserBean

public class UserBean implements Serializable {
 private int userId;
 private String userName;

 public int getUserId() {
  return userId;
 }

 public void setUserId(int userId) {
  this.userId = userId;
 }

 public String getUserName() {
  return userName;
 }

 public void setUserName(String userName) {
  this.userName = userName;
 }
}

用法

<com.lvfq.myworkingtest.dynamic.view.CommentsView
  android:id="@+id/commentView"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:layout_margin="@dimen/dp_20" />

commentView = LvV.find(this, R.id.commentView);
commentView.setList(Data.getComments());
commentView.setOnItemClickListener(new CommentsView.onItemClickListener() {
 @Override
 public void onItemClick(int position, CommentsBean bean) {

 }
});
commentView.notifyDataSetChanged();
