相關數據結構（模擬）
CommentsBean
public class CommentsBean implements Serializable {

private String content;
private UserBean replyUser; // 回復人信息
private UserBean commentsUser; // 評論人信息
public int getCommentsId() {

UserBean

}
public void setUserId(int userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {

用法
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();
