String selection = MySQLiteHelper.STATE + " = 'Maharashtra'" 
      +" AND " + MySQLiteHelper.CITY + " = 'Thane'" 
      +" AND " + MySQLiteHelper.REGION + " = 'Checknaka'"; 

    Cursor cursor = database.query(MySQLiteHelper.RETAILER_TABLE, 
       new String[] {MySQLiteHelper.COLUMN_ID, MySQLiteHelper.SHOP }, selection, 
       null, null, null, null);

可能的原因是，你是指的字符串不''
