我想将时间戳设置为“time ago”，例如1 m前，1天前，10天前等等，在发布我的JSON输出日期之后
{
"id": 15,
"image": "Null",
"title": "Kunal",
"status": "Bjamamnnznnsm",
"profilepic": "Null",
"created_at": "2016-10-15 03:50:20",
"url": "Null"
},
我从feeditem.java获取Volley的时间戳
public FeedItem(int id, String name, String image, String status,
String profilePic, String timeStamp, String url) {
super();
this.id = id;
this.name = name;
this.image = image;
this.status = status;
this.profilePic = profilePic;
this.timeStamp = timeStamp;
this.url = url;
}
这里我从mainactivity到setTimeStamp()获取时间戳值，并通过getTimeStamp()发送到feedlistadapter
public String getTimeStamp() {
return timeStamp;
}
public void setTimeStamp(String timeStamp) {
this.timeStamp = timeStamp;
}
时间戳转换和feedlistadapter：
CharSequence timeAgo = DateUtils.getRelativeTimeSpanString(Long.parseLong(item.getTimeStamp()),new Date().getTime()
, DateUtils.SECOND_IN_MILLIS,DateUtils.FORMAT_ABBREV_RELATIVE);
timestamp.setText(timeAgo);
我的应用程序崩溃了
DateUtils.getRelativeTimeSpanString(Long.parseLong(item.getTimeStamp()),new Date().getTime()`
这是logcat错误
