Question

我已在我的应用中实施了Inapp结算。为此，我使用了按钮。当我点击按钮它进入购买活动，它购买产品。一旦购买产品，该按钮将不可见。并且将显示另一个按钮，允许用户打开产品。这一切都发生得很完美。但是当我再次重新打开应用程序时，可以看到购买按钮。我不希望按钮在购买后可见。一旦用于成功购买，如何使按钮不可见。

StartUpActivity.java

public class StartUpActivity extends PurchaseActivity implements   OnIabSetupFinishedListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
   Log.d("App started");
}
@Override
public void onIabSetupFinished(IabResult result) {
    if (result.isSuccess()) {
        Log.d("In-app Billing set up" + result);
        dealWithIabSetupSuccess();
    } else {
        Log.d("Problem setting up In-app Billing: " + result);
        dealWithIabSetupFailure();
    }
}
@Override
protected void dealWithIabSetupSuccess() {
    navigate().toMainActivity();
    finish();
}
@Override
protected void dealWithIabSetupFailure() {
    popBurntToast("Sorry In App Billing isn't available on your device");
}
}

Answer 1

如果您使用的是API版本3，则可以onCreate()调用getPurchases()方法。

此方法返回用户拥有的当前未消费产品。

这意味着如果您的产品是不可消费的，即用户只会购买一次，那么您将获得必要的信息。

无法解释如何比官方文档更好地解决问题。请查看Querying for Purchased Items主题以获取代码示例。

基本上，您将收到ownedSkus（拥有的产品ID）列表，您只需在此列表上循环，并使您的按钮不可见/可见。

如果您正在寻找的话，请告诉我:)）
