Question

我需要从Google Play中获取从应用结算中购买的所有商品。我可以看到我想要的功能

getAllOwnedSkus()

在谷歌提供的下面的课程中，但它的可见性不公开。我可以简单地将其更改为公开但是必须有另一种方法来获取用户拥有的所有skus？

public class Inventory {
    Map<String,SkuDetails> mSkuMap = new HashMap<String,SkuDetails>();
    Map<String,Purchase> mPurchaseMap = new HashMap<String,Purchase>();

    Inventory() { }

    /** Returns the listing details for an in-app product. */
    public SkuDetails getSkuDetails(String sku) {
        return mSkuMap.get(sku);
    }

    /** Returns purchase information for a given product, or null if there is no purchase. */
    public Purchase getPurchase(String sku) {
        return mPurchaseMap.get(sku);
    }

    /** Returns whether or not there exists a purchase of the given product. */
    public boolean hasPurchase(String sku) {
        return mPurchaseMap.containsKey(sku);
    }

    /** Return whether or not details about the given product are available. */
    public boolean hasDetails(String sku) {
        return mSkuMap.containsKey(sku);
    }

    /**
     * Erase a purchase (locally) from the inventory, given its product ID. This just
     * modifies the Inventory object locally and has no effect on the server! This is
     * useful when you have an existing Inventory object which you know to be up to date,
     * and you have just consumed an item successfully, which means that erasing its
     * purchase data from the Inventory you already have is quicker than querying for
     * a new Inventory.
     */
    public void erasePurchase(String sku) {
        if (mPurchaseMap.containsKey(sku)) mPurchaseMap.remove(sku);
    }

    /** Returns a list of all owned product IDs. */
    List<String> getAllOwnedSkus() {
        return new ArrayList<String>(mPurchaseMap.keySet());
    }

    /** Returns a list of all owned product IDs of a given type */
    List<String> getAllOwnedSkus(String itemType) {
        List<String> result = new ArrayList<String>();
        for (Purchase p : mPurchaseMap.values()) {
            if (p.getItemType().equals(itemType)) result.add(p.getSku());
        }
        return result;
    }

    /** Returns a list of all purchases. */
    List<Purchase> getAllPurchases() {
        return new ArrayList<Purchase>(mPurchaseMap.values());
    }

    void addSkuDetails(SkuDetails d) {
        mSkuMap.put(d.getSku(), d);
    }

    void addPurchase(Purchase p) {
        mPurchaseMap.put(p.getSku(), p);
    }
}

但它的可见性不公开？我可以简单地改变这个但是还有另外一种方法吗？

您正在谈论来自Google的IabHelper申请。这不是官方API，只是您可以使用应用内结算API的示例。您可以以任何方式更改此应用程序。改变它只有一个缺点。如果Google发布此应用的新更新，您需要将更改合并到您的代码中。您拥有的变化越少，合并就越容易。在这方面制定方法public并不是什么大问题。

如何在应用结算中从Google购买所有商品？
