时间戳转换为日期android

Question

有人可以帮助我在我的脚本中将时间戳转换为日期。今天，昨天，昨天和昨天，我有一个listview和我的listview加载正确。前几天我只有时间戳代码？

这是我的主类：

  if(_hasConnection()){ 

      dataList.clear(); 

      System.out.println("Start loading JSON"); 
      JSONArray json = JSONFunctions.getJSONfromURL(Config.DOMAIN + "/report.php?category="+getCategory()+"&image=" + Config.IMAGE_WIDTH + "x" + Config.IMAGE_HEIGHT + "&id=1&date=1&limit=" + Config.LIMIT); 
      System.out.println("End loading JSON"); 

      for (int i = 0; i < json.length(); i++) { 
       try { 
        JSONObject row = json.getJSONObject(i); 

        HashMap<String, String> map = new HashMap<String, String>();  

        map.put("id", row.getString("id")); 
        map.put("title", row.getString("title")); 
        map.put("image", row.getString("image")); 
        map.put("date", row.getString("date")); 
       dataList.add(map); 

       } catch (JSONException e) { 
        e.printStackTrace(); 
       } 
      } 



      System.out.println("End putting in dataList"); 

      adapter.reset(); 

      int continueI = 0; 
      for (int i = 0; i < dataList.size(); i++) { 
       if(i > continueI) { 
        int daysAgo = Utils.daysAgo(dataList.get(i).get("date")); 
        //System.out.println("T: " + dataList.get(i).get("title") + " is daysAgo: " + daysAgo); 

        ArrayList<HashMap<String, String>> objects = new ArrayList<HashMap<String, String>>(); 

        for (int q = 0; q < dataList.size(); q++) { 
         int daysAgoCompare = Utils.daysAgo(dataList.get(q).get("date")); 

         if(daysAgo == daysAgoCompare) { 
          objects.add(dataList.get(q)); 
          continueI = q; 
         } 
        } 

        if(objects.size() > 0) { 
         String dayNaming; 
         if(daysAgo == 0) { 
          dayNaming = getString(R.string.today); 
         }else if(daysAgo == 1) { 
          dayNaming = getString(R.string.yesterday); 
         } 
         else if(daysAgo == 2) { 
          dayNaming = getString(R.string.day_before_yesterday); 
         } 
         else 
         { 
          //SimpleDateFormat dateformatddMMMM = new SimpleDateFormat("dd/MM/yyyy"); 
          dayNaming = String.valueOf(dataList.get(i).get("date")); // new StringBuilder(dateformatddMMMM.format(new Date(Long.parseLong() * 10))).toString(); 
         } 

         //System.out.println("T: " + dayNaming + " is added"); 

         adapter.addSection(dayNaming, new LazyAdapter(getApplicationContext(), Main.this, objects)); 

         //adapter.addSection(dayNaming, new ArrayAdapter<String>(Main.this, R.layout.list_item, objects)); 
        }

简单，你可以时刻字符串改变迄今为止像下面，

long timeStamp = Long.parseLong("your_timestamp_value"); 
Date date = new Date(timeStamp);
