android sqlite中如何求和后赋值到TextView中

[Macksensen]

Intent intent1 = getIntent();
        String key1 = intent1.getStringExtra("one");
        String sum_turnover = "select sum(turnover) from svalue where date like "+"'%" + key1 + "%'";
        String sum_tc = "select sum(tc) from svalue where date like "+"'%" + key1 + "%'";
        Cursor cursor1 = db.rawQuery(sum_turnover,null);
        while ((cursor1.moveToNext())) {
            String stu = cursor1.getString(4);
            sturnover.setText(stu);
            cursor1.close();

这是代码，但是运行后会报错,请问如何将sqlite查询求和后赋值呢

String stu = cursor1.getString(cursor1.getColumnIndex(“sum(turnover)”)); 你试试这样改能不能出来
