这是实体类：
package com.security.phonepolice.entity;
public class Msgbean {
private int id;
private String title;
private String content;
private String relName;
private String relTime;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getRelName() {
return relName;
}
public void setRelName(String relName) {
this.relName = relName;
}
public String getRelTime() {
return relTime;
}
public void setRelTime(String relTime) {
this.relTime = relTime;
}
}
走到这一步法mNotifyLv.setOnRefreshListener(new RefreshListener() 就停了
为什么刷新的时候就是不走接口中的refreshing()方法。求大神指教啊！
