废话不多说，上代码
复制代码 代码如下:
public String getRelativeTimeSpanStringForIphone(long time,long now){
SimpleDateFormat formatter = null;
Resources res = mContext.getResources();
formatter = new SimpleDateFormat("yy-MM-dd");
String yearMonthDay = formatter.format(time);
if(time>now){
return yearMonthDay;
}
formatter = new SimpleDateFormat("E");
String dayOfWeek = formatter.format(time);

formatter = new SimpleDateFormat("kk:mm");
String hourMinuOfTime = formatter.format(time);

formatter = new SimpleDateFormat("kk:mm:ss");

String hourMinuSecOfNow = formatter.format(now);

long millisecOfNow = getMillisecOfNow(hourMinuSecOfNow);

if((now-millisecOfNow<time)||(now-millisecOfNow==time)){
String timeOfCurrentDay = hourMinuOfTime;
String[] hourAndminute = timeOfCurrentDay.split(":");
int hour =Integer.parseInt(hourAndminute[0]);
ContentResolver cv = mContext.getContentResolver();
String strTimeFormat = android.provider.Settings.System.getString(cv,android.provider.Settings.System.TIME_12_24);
if(strTimeFormat!=null){
if(strTimeFormat.equals("12")){
if(hour>12){
return res.getString(R.string.pm)+hour%12+":"+hourAndminute[1];
}else{
return res.getString(R.string.am)+hour%12+":"+hourAndminute[1];
}
}else{
return hour%24+":"+hourAndminute[1];
}
}else{
return hour%24+":"+hourAndminute[1];
}
}else{

if(now-518400000l-millisecOfNow>time){
return yearMonthDay;
}else{
if(now-millisecOfNow-86400000l<time){

return res.getString(R.string.yesterday);

}else{
