按钮，在列表视图 - 机器人 [英] Button in a listview - android

问题描述

我有一个 SimpleAdapter 扩展 ListActivity 作为列表适配器类。我的code是这样的：

I have a class that extends ListActivity with a SimpleAdapter as the list adapter. My code looks like this:

public class ListOfFirms extends ListActivity {

Intent extras;
int time;
String km;
ArrayList<String> firms = new ArrayList<String>(); 
SimpleAdapter adapter;  
static final ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();





  @Override
  public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.firms);


        extras = getIntent();

        time = extras.getIntExtra("time", 0); 
        km = extras.getStringExtra("km");

        adapter = new SimpleAdapter(
                this, list, R.layout.taxi_custom,
                new String[] {"name","price"},
                new int[] {R.id.taxi_name,R.id.taxi_price});

        initializeFirm();
        setListAdapter(adapter);
     }  

我的问题是我怎么可以在列表中添加一个按钮，每一个元素，按钮应浮动权。我的列表包含类公司，我怎么能知道哪个对象，我从列表中抢出来的对象，当用户presses这个按钮？

My question is how I can add a button to each element in the list, the button should be floating to right. My list contains object of the class Firm, how can I know which object that I grab out from the list, when a user presses this button?
