android开发实例时间戳转时间

最近做腾讯微博的demo，服务器返回的时间戳（timestamp），怎么把Int型的时间戳转成时间呢？

java时间戳精确到毫秒，腾讯微博返回时间戳为秒，需注意。

import java.sql.Timestamp;
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class GetTimeUtil {
    
    
      public static String getDate(String month,String day){
   	  SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//24小时制
  		    java.util.Date d = new java.util.Date(); ;
  		    String str = sdf.format(d);
  		   String nowmonth = str.substring(5, 7);
			String nowday = str.substring(8,10 );
   	  String result = null;
   	  
   		int temp =   Integer.parseInt(nowday)-Integer.parseInt(day);
   	    switch (temp) {
			case 0:
				result="今天";
				break;
			case 1:
				result = "昨天";
				break;
			case 2:
				result = "前天";
				break;
			default:
				StringBuilder sb = new StringBuilder();
				sb.append(Integer.parseInt(month)+"月");
				sb.append(Integer.parseInt(day)+"日");
				result  = sb.toString();
				break;
			}
   	  return result;
      }
      public static String getTime(int timestamp){
   	  SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  			String time= null;
  		try {
  			java.util.Date currentdate = new java.util.Date();//当前时间
  			
  			long i = (currentdate.getTime()/1000-timestamp)/(60);
  			System.out.println(currentdate.getTime());
  			System.out.println(i);
  			Timestamp now = new Timestamp(System.currentTimeMillis());//获取系统当前时间
  			System.out.println("now-->"+now);//返回结果精确到毫秒。
  			 
  			String str = sdf.format(new Timestamp(IntToLong(timestamp)));
  			time = str.substring(11, 16);
  			 
  			String month = str.substring(5, 7);
  			String day = str.substring(8,10 );
  			System.out.println(str);
  			System.out.println(time);
  			System.out.println(getDate(month, day));
  			time =getDate(month, day)+ time;
  		} catch (Exception e) {
  			// TODO Auto-generated catch block
  			e.printStackTrace();
  		}
  	return time;
      }
      //java Timestamp构造函数需传入Long型
      public static long IntToLong(int i){
    	  	long result = (long)i;
    	  	  result*=1000;
    	  	 return  result;
    	     }
      public static void main(String[] args) {
    	  int timestamp = 1310457552;  // 假设腾讯微博返回时间戳为秒
    	  String time = GetTimeUtil.getTime(timestamp);
    	  System.out.println("timestamp-->"+time);
      //print  timestamp-->7月12日15:59
      }
      
      }
