Answer 1

나는 얇은 당신은

listview.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 
      // TODO Auto-generated method stub 


       // do your work here 

     } 
    }); 

Answer 2

아래에 따라 당신의 listView1에 대한 OnItemClickListener를 설정하고 실행하려고하는 시도이다.

listView1.setOnItemClickListener(new OnItemClickListener() 
{ 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
    { 
     CanteenTagEntry tagentry = null; 
     int pos = position; 
     int id = arr[pos]; 
     int userid = 0; 
     Context con = getApplicationContext(); 
     DatabaseHelper dbHelper = new DatabaseHelper(con); 
     ICanteenLogRepository repository = dbHelper.getCanteenLogRepository(); 

     try 
     { 
      tagentry = repository.Retrieve(id); 
      userid = tagentry.getUser().getId(); 
     } catch (SQLException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 

     try 
     { 
      StartFood food = new StartFood(id, userid); 
     } catch (SQLException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 
} 

Answer 3

이 같은 행에 리스너를 설정행을 반환하기 전에 사용해야합니다.

row.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 
             // your code 
       } 
      });
