私はあなたが使用する必要がある薄い

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 

        }
    });

以下のように設定OnItemClickListenerlistView1て実行してみてください。

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();
        }
    }
}

行を返す前にリスナーを次のような行に設定します。

row.setOnClickListener(new OnClickListener() {

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