Question

使用twitter 4j库，我抓住用户的最新推文，然后获取转推ID和他们的粉丝数。现在我需要做的是显示转发者的ID，按照跟随者的降序排序，即最高的跟随者第一等级。我抓住并将追随者数量计入树图，现在如何对它们进行排序？然后在TextView中显示它们？
使用twitter4j，我抓住用户的推文并将其置于“状态”状态。其余部分是： -

//get  the first status
        status = statuses.get(0);
     //get id of the status
          long l= status.getId(); 
        //get retweeters id
          ki =twitter.getRetweeterIds(l, 100, -1);

         long[] id=ki.getIDs();
         //for every retweeter id, get followers count and put in treemap
         TreeMap<Integer,Long> tm = new TreeMap<Integer, Long>();
         for(int k=0;k<=id.length;k++)
         {
             u = twitter.showUser(id[k]);
             follower=u.getFollowersCount();
             tm.put(follower,id[k] );
         }
        NavigableMap<Integer,Long> reverseTreeMap = tm.descendingMap();

解决！这就是我做的方式

//Using treemap to sort retweeters according to their followers
 TreeMap<Integer,String> tm = new TreeMap<Integer, String>();
 try{
     for(int k=0;k<10;k++)
         {
             publishProgress(5);
             Log.i(a, "treemap followers"+k);
             u = twitter.showUser(id[k]);
             follower=u.getFollowersCount();
             url=u.getProfileImageURL();
             tm.put(follower,url );
         }
    }
catch(Exception e)
    {
        Log.e(a, e.toString());
    }
Log.i(a, "Done treemap");

 //Reverse the order of the treemap 
 Log.i(a, "Reversing Treemap");
 NavigableMap<Integer,String> reverseTreeMap = tm.descendingMap();
 publishProgress(5);

 //Put treemap values in string array
 s=reverseTreeMap.values().toString();
 s=s.replace("[", "");
 s=s.replace("]", "");
  Log.i(a, "Done");

//使用String数组在Textview或任何地方显示它们

如何对从twitter api抓取的树图的值进行排序并在TextView（android）中显示？
