嗨，我试图从json提要创建一个列表，每个日期有一个标题，然后在下面的内容。然而，我没有按照日期顺序来组织json feed，我已经创建了一个for循环来获取所有日期，然后检查重复项，这给了我一个来自feed的日期数组。然后我想为每个日期的适配器添加一个标题视图，我想我需要添加另一个循环来获取每个日期下的内容？问题是目前我的标题查看Android在for循环中添加视图

所以我的问题是我如何创建一个基于for循环添加标题视图的列表，然后在每个标题下添加其他视图？

这里是我的功能，我是一个的AsyncTask

public void FillData() throws JSONException{  
     ListView list = getListView(); 
     list.scrollTo(0, 0); 
     list.setVerticalFadingEdgeEnabled(false); 
      list.setTextFilterEnabled(true); 
      LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      View header = inflater.inflate(R.layout.homeheader, list, false); 
     fixturesView = LayoutInflater.from(getBaseContext()).inflate(R.layout.fixturescell, 
       null); 
     //Log.v("MyFix", "fixturesArray = " + fixturesArray); 
     if(fixturesArray.length() < 1){ 
      TextView emptytext = (TextView) fixturesView.findViewById(R.id.TextView02); 
      emptytext.setText("No Upcoming Fixtures Available"); 
     }else{ 
     try{ 
      for(int t = 0; t < fixturesArray.length(); t++){ 
       JSONObject matchDateDict = fixturesArray.getJSONObject(t); 
       String matchDate = matchDateDict.getString("matchdate"); 
       if(matchDatesArray.length() != 0){ 
        int lm = t - 1; 
        JSONObject lastDateDict = fixturesArray.getJSONObject(lm); 
        String lastMatchDate = lastDateDict.getString("matchdate"); 
        Log.v("MyFix", "lastMatchDate " + lastMatchDate); 
        if(matchDate.equals(lastMatchDate)){ 
         Log.v("MyFix", "2 are the same");       
        } else { 
         Log.v("MyFix", "add new matchdate to array"); 
         matchDatesArray.put(matchDate); 
        } 
       } else { 
        Log.v("MyFix", "add new matchdate to array (first time only)");      
        matchDatesArray.put(matchDate);  
       } 
      } 
      Log.v("MyFix", "matchDatesArray = " + matchDatesArray); 
     }catch (JSONException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
     DateHeader = LayoutInflater.from(getBaseContext()).inflate(R.layout.redcell, 
       null); 
     adapter = new MergeAdapter(); 
     for(int t = 0; t < matchDatesArray.length(); t++){  
      JSONObject mdheaderdict = matchDatesArray.getJSONObject(t); 
      String matchheader = mdheaderdict.getString("matchdate"); 
       TextView matchdayheader = (TextView) DateHeader.findViewById(R.id.redheadertext); 
       matchdayheader.setText(matchheader); 
       adapter.addView(DateHeader); 
     }    
    }  
     setListAdapter(adapter); 
}

继承人的JSON提要
