还是老流程，先来看一下效果图：

然后是主要实现代码：

相关数据结构（模拟）

CommentsBean

public class CommentsBean implements Serializable {
private int commentsId;
private String content;
private UserBean replyUser; // 回复人信息
private UserBean commentsUser; // 评论人信息

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();
