“setOnItemClickListener”和“setOnClickListener”之间的区别

Question

我有一个自定义数组列表，显示来自我的Sqlite数据库的数据，我的问题是当我点击该项目时（从列表视图中，除了第一项），它得到错误数据（从我的数据库），但是当我用相同的代码实现了一个按钮（在ListAdapter内）它工作得很好。

'Array list'里面的“setOnItemClickListener”和“setOnClickListener”有什么区别？我该如何解决它？

谢谢

public class ViewTeam extends Activity { 

private ListView listview; 

TextView totalrecords; 
DBHelper db; 
public ArrayList<TeamModel> _teamlist = new ArrayList<TeamModel>(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.viewteam); 

    totalrecords = (TextView) findViewById(R.id.totalrecords1); 
    listview = (ListView) findViewById(R.id.listview1); 
} 

@Override 
protected void onResume() { 
    // TODO Auto-generated method stub 
    super.onResume(); 

    _teamlist.clear(); 

    db = new DBHelper(getApplicationContext()); 
    db.getWritableDatabase(); 
    ArrayList<TeamModel> team_list = db.getTeams(); 

    for (int i = 0; i < team_list.size(); i++) { 

     String tname = team_list.get(i).getTeamname(); 

     System.out.println("tname>>>>>" + tname); 
     String topponent = team_list.get(i).getTeamopponent(); 
     String tdate = team_list.get(i).getTeamdate(); 

     TeamModel _TeamModel = new TeamModel(); 

     //_TeamModel.setIdno(tidno); 
     _TeamModel.setTeamname(tname); 
     _TeamModel.setTeamopponent(topponent); 
     _TeamModel.setTeamdate(tdate); 

     _teamlist.add(_TeamModel);

       startActivity(intent); 

      }

而不是使用temp你应该使用position参数通过OnItemClickListener传递给您的数据

  listview.setOnItemClickListener(new AdapterView.OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1,int position, long arg3) 
     { 
      String _teamname = String.valueOf(_teamlist 
        .get(position).getTeamname()); 
      String _teamopponent = _teamlist.get(position) 
        .getTeamopponent(); 
      String _teamdate = _teamlist.get(position) 
        .getTeamdate(); 

      Intent intent = new Intent(ViewTeam.this, 
        AddReminder.class); 

      Bundle bundle = new Bundle(); 
      bundle.putString("name1", _teamname); 
      bundle.putString("opponent1", _teamopponent); 
      bundle.putString("date1", _teamdate); 
      intent.putExtras(bundle); 
      startActivity(intent);    } 
    });
