Android SQLlite Database query not ordering

I am working with sqlite query where I am selecting multiple records from Database Table by passing ids to the db table. Now I want when I select the records they should be ORDERED. But its not ordering, below is my query please tell me where I am doing the wrong.

"SELECT * FROM tbl_product WHERE productId IN (" + makePlaceholders(ids.length)+")"+ " ORDER BY rating DESC";

It only returns the records match with the given ids but they are not in order.

And here is my makePlaceholders method

public String makePlaceholders(int len){
        if(len > 0){
        StringBuilder nameBuilder = new StringBuilder();
        for(int i = 0; i < len; i++){
            nameBuilder.append("?").append(",");
        }
        nameBuilder.deleteCharAt(nameBuilder.length() - 1);

        return nameBuilder.toString();
        } else{
            return null;
        }
    }
