java - 用户购买时如何刷新活动？
问题描述
我有一个用于用户购买时的对话框片段。从 MainActivity 打开片段，如下所示：
DialogPurchasePizza dialogPurchasePizza = new DialogPurchasePizza(getApplicationContext());
dialogPurchasePizza.show(getSupportFragmentManager(), "Pizza Dialog");
这是对话片段：
public class DialogPurchasePizza extends AppCompatDialogFragment implements PurchasesUpdatedListener {
private BillingClient billingClient;
private final List<String> skuList = new ArrayList<>();
private final String sku = "com.goodweathercorp.perappbrightness.pizzafordev";
Button noButton;
Button buyButton;
Context context;
public DialogPurchasePizza(Context context) {
this.context = context;
}
@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) { // Called when making a purchase
setRetainInstance(true); //Dialog is not killed on screen orientation change, just paused and reused.
MaterialAlertDialogBuilder builder = new MaterialAlertDialogBuilder(requireActivity(), R.style.MaterialAlertDialog_rounded);
LayoutInflater inflater = requireActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.purchase_dialog, null);
builder.setView(view);
skuList.add(sku); //add all purchases to the list
noButton = view.findViewById(R.id.noButton);
buyButton = view.findViewById(R.id.buyButton);
buyButton.setEnabled(false); //set it to disabled at first until the BillingClient is ready
MaterialToolbar purchaseToolbar = view.findViewById(R.id.purchaseToolbar);
TextView reset_title = purchaseToolbar.findViewById(R.id.titleTextView);
reset_title.setText(R.string.pizza_for_dev);
reset_title.setTextColor(Color.WHITE);
setupBillingClient(context);
noButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
return builder.create();
}
private void setupBillingClient(Context c) { //connect to google play
billingClient = BillingClient.newBuilder(c)
.enablePendingPurchases()
.setListener(this)
.build();
billingClient.startConnection(new BillingClientStateListener() {
@Override
public void onBillingSetupFinished(@NonNull BillingResult billingResult) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
//The BillingClient is setup successfully
loadAllSkus();
}
}
@Override
public void onBillingServiceDisconnected() {
//TODO: implement retry logic to handle lost connections to Google Play by calling startConnection() again
}
});
}
private void loadAllSkus() {
if (billingClient.isReady()) { //first check if BillingClient is ready
final SkuDetailsParams params = SkuDetailsParams.newBuilder()
.setSkusList(skuList)
.setType(BillingClient.SkuType.INAPP)
.build();
billingClient.querySkuDetailsAsync(params, new SkuDetailsResponseListener() {
@Override
public void onSkuDetailsResponse(@NonNull final BillingResult billingResult, @Nullable List<SkuDetails> skuDetailsList) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
assert skuDetailsList != null;
for (Object skuDetailsObject : skuDetailsList) {
final SkuDetails skuDetails = (SkuDetails) skuDetailsObject;
if (skuDetails.getSku().equals(sku)) { //if it found the sku in play store you can start billing flow
Purchase.PurchasesResult result = billingClient.queryPurchases(BillingClient.SkuType.INAPP); //use play store cache, no network
List<Purchase> purchases = result.getPurchasesList();
boolean isOwned = false;
if (purchases != null) //first check if he has already purchased
for (Purchase purchase : purchases) {
String thisSKU = purchase.getSku();
if (thisSKU.equals(sku)) {
isOwned = true;
break;
}
}
if (!isOwned) {
buyButton.setEnabled(true);
buyButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
BillingFlowParams billingFlowParams = BillingFlowParams
.newBuilder()
.setSkuDetails(skuDetails)
.build();
if (getActivity() != null)
billingClient.launchBillingFlow(getActivity(), billingFlowParams);
dismiss();
}
});
}
}
/* else if (skuDetails.getSku().equals("something else")) { //add other products
}*/
}
}
}
});
} else Toast.makeText(context, R.string.billing_not_ready, Toast.LENGTH_LONG).show();
}
@Override
public void onPurchasesUpdated(@NonNull BillingResult billingResult, @Nullable List<Purchase> purchases) {
int responseCode = billingResult.getResponseCode();
if (responseCode == BillingClient.BillingResponseCode.OK && purchases != null) {
for (Purchase purchase : purchases) {
handlePurchase(purchase); //acknowledge the purchase
}
} else if (responseCode == BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED) {
Toast.makeText(context, R.string.item_already_owned, Toast.LENGTH_LONG).show();
} else if (responseCode == BillingClient.BillingResponseCode.USER_CANCELED) {
Toast.makeText(context, R.string.user_cancelled, Toast.LENGTH_LONG).show();
}
}
private void handlePurchase(Purchase purchase) {
if (purchase.getSku().equals(sku) && purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
if (!purchase.isAcknowledged()) {
AcknowledgePurchaseParams acknowledgePurchaseParams =
AcknowledgePurchaseParams.newBuilder()
.setPurchaseToken(purchase.getPurchaseToken())
.build();
billingClient.acknowledgePurchase(acknowledgePurchaseParams, new AcknowledgePurchaseResponseListener() {
@Override
public void onAcknowledgePurchaseResponse(@NonNull BillingResult billingResult) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
Toast.makeText(context, R.string.purchase_done, Toast.LENGTH_LONG).show();
SharedPreferences pizza2 = context.getSharedPreferences("pizzaConfig", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = pizza2.edit();
editor.putBoolean("purchased_right_now", true);
editor.apply();
Intent refresh = new Intent(context, MainActivity.class);
refresh.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); //clears previous activities
startActivity(refresh);
}
}
});
}
}
}
}
重要的部分在片段的最后一个方法中，handlePurchase(Purchase purchase). 我打算在这里发生的是，当确认购买时，会显示一个 Toast，告诉用户购买完成，然后重新创建主要活动。奇怪的问题是 Toast 已成功显示，但未重新创建活动。我在多个设备上对此进行了测试并得到了相同的结果。更重要的是测试这个问题非常困难，因为它需要创建一个全新的 Gmail 帐户并将其添加到游戏控制台，每次我想模拟一个购买确认时。那么为什么没有重新创建主要活动呢？
