Answer 1

Problem ist mit den SQL query.Its wie

INSERT INTO TABLE_NAME [(column1, column2, column3,...columnN)] 
VALUES (value1, value2, value3,...valueN); 

So für Ihren Fall

String query = String.format("INSERT INTO OrderDetail(ProductId,ProductName,Quantity,Price,Discount)VALUES('%s','%s','%s','%s','%s');", order.getProductId(), order.getProductName(), order.getQuantity(), order.getPrice(), order.getDiscount()); db.execSQL(query); 

Hope this helfen.

Answer 2

Ihr query falsch ist

Verwendung INSERT INTO statt INSERT FROM

Versuchen Sie, diese

public void addToCart (Order order) 
    { 
     SQLiteDatabase db = getReadableDatabase(); 
     String query = String.format("INSERT INTO OrderDetail(ProductId,ProductName,Quantity,Price,Discount)VALUES('%s','%s','%s','%s','%s');", 
       order.getProductId(), 
       order.getProductName(), 
       order.getQuantity(), 
       order.getPrice(), 
       order.getDiscount()); 
     db.execSQL(query); 

    }
