Android的列表视图使用节 [英] Android Listview with sections

问题描述

我有一个问题想了解列表视图如何切片工作。我有它的工作成为一个正常的列表视图。但现在我想部分添加到我的清单。如何我在广告节头。

这是我的code，它的工作原理。

 公共类ChooseTeamActivity扩展ListActivity {
    @覆盖
    保护无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;

    的setContentView（R.layout.chooseact）;

    串FullData = getIntent（）getStringExtra（FullData）;

    尝试{

      JSONObject的OBJ =新的JSONObject（FullData）;
      名单＆LT;字符串＆GT;联赛=新的ArrayList＆LT;字符串＆GT;（）;

      JSONObject的objData = obj.getJSONObject（数据）;

      JSONArray jArray = objData.getJSONArray（结构）;


      的for（int i = 0; I＆LT; jArray.length（）;我++）{
        的JSONObject oneObject = jArray.getJSONObject（ⅰ）;
        leagues.add（oneObject.getString（league_website_name））;
        JSONArray DivisionsArray = oneObject.getJSONArray（区划）;

        对于（INT D = 0; D＆LT; D​​ivisionsArray.length（）; d ++）{
           JSONObject的DivDict = DivisionsArray.getJSONObject（D）;
           leagues.add（DivDict.getString（名字））;
        }
     }

      setListAdapter（新ArrayAdapter＆LT;字符串＆GT;（这一点，R.layout.single_item，
                                                                    联赛））;

      ListView控件列表= getListView（）;
      list.setTextFilterEnabled（真正的）;

    }赶上（JSONException E）{
        e.printStackTrace（）;
    }
    }
}

Hi I am having an issue trying to understand how sectioned ListViews work. I had it working into a normal list view. but now I want to add sections to my list. How to I ad a section header in.

Heres my code that works.

public class ChooseTeamActivity extends ListActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    setContentView(R.layout.chooseact);    

    String FullData = getIntent().getStringExtra("FullData");

    try{

      JSONObject obj = new JSONObject(FullData);
      List<String> leagues = new ArrayList<String>();

      JSONObject objData = obj.getJSONObject("data");

      JSONArray jArray = objData.getJSONArray("structure");


      for (int i=0; i < jArray.length(); i++) {
        JSONObject oneObject = jArray.getJSONObject(i);   
        leagues.add(oneObject.getString("league_website_name"));
        JSONArray DivisionsArray = oneObject.getJSONArray("divisions");

        for (int d=0; d < DivisionsArray.length(); d++){            
           JSONObject DivDict = DivisionsArray.getJSONObject(d);   
           leagues.add(DivDict.getString("name"));              
        }               
     }         

      setListAdapter ( new ArrayAdapter<String>(this, R.layout.single_item, 
                                                                    leagues));

      ListView list = getListView();
      list.setTextFilterEnabled(true);

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

解决方案

A quick google of "android sectioned listview" will return results for example http://w2davids.wordpress.com/android-sectioned-headers-in-listviews/

In fast summary though you end up writing a list adapter that returns a header layout when needed, and a row layout when needed.
