我怎样才能得到我点击的列表项数据？

Question

我有一些ListView和SimpleAdapter

List<HashMap<String, Object>> dataList = new ArrayList<HashMap<String, Object>>(); 

    HashMap<String, Object> map = new HashMap<String, Object>(); 
    map.put(ITEMTITLE, getString(R.string.broadcast_street_1_text)); 
    map.put(ITEMDESCR, getString(R.string.broadcast_request_1_text)); 
    dataList.add(map); 

    map = new HashMap<String, Object>(); 
    map.put(ITEMTITLE, getString(R.string.broascast_street_2_text)); 
    map.put(ITEMDESCR, getString(R.string.broadcast_request_2_text)); 
    dataList.add(map); 

    SimpleAdapter adapter = new SimpleAdapter(this, 
               dataList, 
               R.layout.broadcast_list_item, 
               new String[] {ITEMTITLE, ITEMDESCR}, 
               new int[] {R.id.broadcast_list_item_title, R.id.broadcast_list_item_descr}); 

    list.setAdapter(adapter); 

所以，当我在一些列表项点击我需要改变的活动。

 list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) { 
      Intent intent = new Intent(getParent(), BroadcastDataActivity.class); 
      intent.putExtra("street", arg0.getItemAtPosition(position).toString()); 
      intent.putExtra("time", arg0.getItemAtPosition(position).toString()); 
      parentActivity = (WorldTaxiActivityGroup) getParent(); 
      parentActivity.startChildActivity("BroadcastData", intent); 
     } 
    }); 

但arg0.getItemAtPosition（位置）只返回数据的对象 请帮助我，我怎样才能得到的数据正确地将？

Answer 1

使用

list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) { 
      Intent intent = new Intent(getParent(), BroadcastDataActivity.class); 
      HashMap<String, Object> item = dataList.get(position); 
      intent.putExtra("street", item.get(ITEMTITLE).toString(); 
      intent.putExtra("time", item.get(ITEMDESCR).toString().toString()); 
      parentActivity = (WorldTaxiActivityGroup) getParent(); 
      parentActivity.startChildActivity("BroadcastData", intent); 
     } 
    }); 

Answer 2

public void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) { 
      Intent intent = new Intent(getParent(), BroadcastDataActivity.class); 
      intent.putExtra("street", dataList.get(position).get("ITEMTITLE")); 
      intent.putExtra("time", dataList.get(position).get("ITEMDESCR")); 
      parentActivity = (WorldTaxiActivityGroup) getParent(); 
      parentActivity.startChildActivity("BroadcastData", intent); 
     } 
    });
