小编Sur*_*esh的帖子

我已经浏览了Play计费库 https://developer.android.com/google/play/billing/billing_library_overview。 您必须在三天内确认所有购买。如果未正确确认购买，将导致这些购买被退款。该过程没有明确说明如何确认购买。这就是我尝试过的方法吗？提前致谢

@Override


 public void onPurchasesUpdated(BillingResult billingResult, @Nullable List<Purchase> purchases) {
        if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.OK&&purchases!=null){
            Toast.makeText(this, "Purchase Successful", Toast.LENGTH_SHORT).show();
            for(Purchase purchase:purchases){
                handlePurchase(purchase);
            }
        }else if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.USER_CANCELED){
            Toast.makeText(this, "Purchase Cancelled", Toast.LENGTH_SHORT).show();
        }else if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED){
            Toast.makeText(this, "Already Purchased", Toast.LENGTH_SHORT).show();
        } else{
            Toast.makeText(this, billingResult.getDebugMessage(), Toast.LENGTH_SHORT).show();
        }



    //in handlePurchase()
 if(!purchase.isAcknowledged())
{ 
          AcknowledgePurchaseParams acknowledgePurchaseParams
                    = AcknowledgePurchaseParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .setDeveloperPayload(purchase.getDeveloperPayload())
                    .build();

            client.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener() {
                @Override
                public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
                    if(billingResult.getResponseCode()== BillingClient.BillingResponseCode.OK){
                        Toast.makeText(RemoveAdsActivity.this, "Purchase Acknowledged", Toast.LENGTH_SHORT).show();
                    }
                }
            });
        }
