我如何從android listview中獲取值？

嗨，這是我的代碼我想訪問KEY_ID，我把地圖列表放在列表項中點擊一個變量.. 請幫我我如何做到這一點。我如何從android listview中獲取值？

ArrayList (HashMap) (String, String) mapList = new ArrayList(HashMap(String, String))(); 
    XMLParser parser = new XMLParser(); 
    Document doc = parser.getDomElement(xml); 
// getting DOM element 
    NodeList nl = doc.getElementsByTagName(KEY_Route); 

    // looping through all song nodes <song> 
    for (int i = 0; i < nl.getLength(); i++) { 
     // creating new HashMap 
     HashMap<String, String> map = new HashMap<String, String>(); 

     Element e = (Element) nl.item(i); 

     // adding each child node to HashMap key => value 

     map.put(KEY_ID, parser.getValue(e, KEY_ID)); 
     map.put(KEY_SchoolName, parser.getValue(e, KEY_SchoolName)); 
     map.put(KEY_ChildrenName, parser.getValue(e, KEY_ChildrenName)); 
     map.put(KEY_AlertTime, parser.getValue(e, KEY_AlertTime)); 
     map.put(KEY_RouteName, parser.getValue(e, KEY_RouteName)); 
     map.put(KEY_Notification, parser.getValue(e, KEY_Notification)); 
     map.put(KEY_StopName, parser.getValue(e, KEY_StopName)); 
     // adding HashList to ArrayList 
     mapList.add(map); 
    } 

    list = (ListView) findViewById(R.id.list); 

    // Getting adapter by passing xml data ArrayList 
    adapter = new LazyAdapter(this, mapList); 
    list.setAdapter(adapter); 

    // Click event for single list row 
    list.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> parent, View view, 
       int position, long id) { 
      int idw = position; 
      long logss = id; 

// There i want to access the KEY_ID..    

      } catch (Exception e) { 
       e.printStackTrace(); 
       progressDialog.dismiss(); 
      } 

     } 
    }); 
}

在你onItemClick方法，您需要從MAPLIST對象從特定位置出來取HaspMap：

HashMap<String, String> map = mapList.get(position); 

//and then read values out from 'map' object

感謝兄弟我得到了我想要的價值感謝很多男人:) – 2012-04-10 12:24:24

但我已經把最終的maplist放在最前面了。 – 2012-04-10 12:25:15

這並不重要，因爲你正在閱讀的價值，而不是分配給它 – waqaslam 2012-04-10 12:45:26

使用此代碼來獲取的位置選定的listitem。

ListView lv1 = (ListView) findViewById(R.id.ListView01); 

    lv1.setOnItemClickListener(new OnItemClickListener() { 
      public void onItemClick(AdapterView<?> a, View v, int position, long id) { 

      Object o = lv1.getItemAtPosition(position); 

     } 
    });
