Sqlite SimpleCrsorAdapter和事件自动加载更多（在滚动上加载数据）

我的英语很差，所以很难描述下面的问题。打扰大家：）：）

我有一个代码如下：

String sql = "select * from " + MySQLiteOpenHelper.tb_name
                + " where " + MySQLiteOpenHelper.cl_id_atm + " > 0 and "
                + MySQLiteOpenHelper.cl_id_atm + " <= 300";
cursor = dataHelper.SELECTSQL(sql);

        while (cursor.moveToNext()) {

            String id = cursor.getString(cursor
                    .getColumnIndex(MySQLiteOpenHelper.cl_id_atm));

            String Bank = cursor.getString(cursor
                    .getColumnIndex(MySQLiteOpenHelper.cl_bank));
            String Address = cursor.getString(cursor
                    .getColumnIndex(MySQLiteOpenHelper.cl_address));
            Log.d(TAG, "id: " + id + " Bank: " + Bank + " address: "
                    + Address);
        }
String[] from = { MySQLiteOpenHelper.cl_bank,
                MySQLiteOpenHelper.cl_address };
        int[] to = { R.id.tvBank, R.id.tvAddress };
adapter = new SimpleCursorAdapter(AtmActivity.this,
                R.layout.item_atm_layout, cursor, from, to);
setListAdapter(adapter);

String sql=“select*from”+MySQLiteOpenHelper.tb\u name
+其中“+MySQLiteOpenHelper.cl_id_atm+”>0和
+MySQLiteOpenHelper.cl_id_atm+”
