这是使用WHERE及其参数形成SQLite查询的正确方法，因为我收到错误，索引4处的绑定值为null。
public Cursor getBankomatLocation(){
SQLiteDatabase db = getReadableDatabase();
SQLiteQueryBuilder qb = new SQLiteQueryBuilder();
String [] sqlSelect = {"0 _id", "Naslov", "Kraj"};
String sqlTables="Bankomati_db";
String sqlWhere = "Banka=? AND(Posta BETWEEN ? AND ? OR Kraj = ?)";
String [] args ={selectedBank, selectedPostaPod, selectedPostaNad, selectedKraj};
Log.d("getBankomatLocation", "selectedBank" + selectedBank);
qb.setTables(sqlTables);
Cursor c =qb.query(db, sqlSelect, sqlWhere, args, null, null, null);
c.moveToFirst();
return c;
}
SQL语句：SELECT Naslov，Kraj FROM Bankomati_db其中Banka = SelectedBank AND（Posta BETWEEN selectedPostaPod AND SelectedPostaNad OR kraj = selectedKraj）
