我的应用内应用结算存在问题。我认为它在上周运作良好，但我得到了意想不到的结果。
我有大约10件待售物品。购买时，每个项目将共享的pref值设置为true，如果已购买则查询库存。一个项目是“全部购买”按钮，当购买时，它假设将所有其他的值设置为真。这很好用，当我添加新商品时会出现问题。 “全部购买”也可以访问这些，但似乎不是。
我会尝试让代码尽可能简单，同时仍然显示所需的信息： BaseActivity.java（所有应用内购买设置）：
//SKU FOR our products
static final String SKU_W31 = "workout_31";
static final String SKU_W32 = "workout_32";
static final String SKU_W37 = "workout_37";
static final String SKU_ALL = "all_workouts";
//is paid?
public boolean m31paid = false;
public boolean m32paid = false;
public boolean m37paid = false;
public boolean mAllPaid = false;
IabHelper mHelper;
IabBroadcastReceiver mBroadcastReceiver;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0);
mHelper = new IabHelper(this, base64EncodedPublicKey);
//SET FALSE FOR LIVE APP
mHelper.enableDebugLogging(false);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
Log.d(LOG, "Problem setting up in app billing: " + result);
} else Log.d(LOG, "set up correctly!");
if (mHelper == null) return;
mBroadcastReceiver = new IabBroadcastReceiver(BaseActivity.this);
IntentFilter broadcastFilter = new IntentFilter(IabBroadcastReceiver.ACTION);
registerReceiver(mBroadcastReceiver, broadcastFilter);
// IAB is fully set up. Now, let's get an inventory of stuff we own.
Log.d(LOG, "Setup successful. Querying inventory.");
try {
mHelper.queryInventoryAsync(mGotInventoryListener);
} catch (IabHelper.IabAsyncInProgressException e) {
complain("Error querying inventory. Another async operation in progress.");
}
}
});
}
IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener() {
public void onQueryInventoryFinished(IabResult result, Inventory inventory) {
Log.d(LOG, "Query inventory finished.");
SharedPreferences.Editor editor = getSharedPreferences("my_pref", MODE_PRIVATE).edit();
// Have we been disposed of in the meantime? If so, quit.
if (mHelper == null) return;
Purchase w37Purchase = inventory.getPurchase(SKU_W37);
m37paid = (w37Purchase != null && verifyDeveloperPayload(w37Purchase));
Log.d(LOG, "User has workout 37" + (m37paid ? "BOUGHT" : "NOT BOUGHT"));
if (w37Purchase != null) {
editor.putBoolean("workout37", true);
editor.apply();
}
Purchase w32Purchase = inventory.getPurchase(SKU_W32);
m32paid = (w32Purchase != null && verifyDeveloperPayload(w32Purchase));
Log.d(LOG, "User has workout 32" + (m32paid ? "BOUGHT" : "NOT BOUGHT"));
if (w32Purchase != null) {
editor.putBoolean("workout32", true);
editor.apply();
}
Purchase w31Purchase = inventory.getPurchase(SKU_W31);
m31paid = (w31Purchase != null && verifyDeveloperPayload(w31Purchase));
Log.d(LOG, "User has workout 31" + (m31paid ? "BOUGHT" : "NOT BOUGHT"));
if (w31Purchase != null) {
editor.putBoolean("workout31", true);
editor.apply();
}
Purchase wAllPurchase = inventory.getPurchase(SKU_ALL);
mAllPaid = (wAllPurchase != null && verifyDeveloperPayload(wAllPurchase));
Log.d(LOG, "User has " + (mAllPaid ? "BOUGHT" : "NOT BOUGHT"));
if (wAllPurchase != null) {
editor.putBoolean("workout31", true);
editor.putBoolean("workout32", true);
editor.putBoolean("workout37", true);
editor.apply();
}
}};
然后我有购买的方法，我把它放在相应按钮的onClick上：
public void onBuy31ButtonClicked (View arg0) {
Log.d(LOG, "Buy 31 button clicked.");
if (m31paid) {
Toast.makeText(getApplicationContext(), R.string.already_bought, Toast.LENGTH_LONG).show();
return;
}
Log.d(LOG, "launching purchase for 31");
String payload = "";
try {
mHelper.launchPurchaseFlow(this, SKU_W31, RC_REQUEST, mPurchaseFinishedListener, payload);
} catch (IabHelper.IabAsyncInProgressException e) {
Toast.makeText(getApplicationContext(), R.string.purchase_error, Toast.LENGTH_LONG).show();
}
}
public void onBuy32ButtonClicked (View arg0) {
Log.d(LOG, "Buy 32 button clicked.");
if (m32paid) {
Toast.makeText(getApplicationContext(), R.string.already_bought, Toast.LENGTH_LONG).show();
return;
}
Log.d(LOG, "launching purchase for 32");
String payload = "";
try {
mHelper.launchPurchaseFlow(this, SKU_W32, RC_REQUEST, mPurchaseFinishedListener, payload);
} catch (IabHelper.IabAsyncInProgressException e) {
Toast.makeText(getApplicationContext(), R.string.purchase_error, Toast.LENGTH_LONG).show();
}
}
public void onBuy37ButtonClicked (View arg0) {
Log.d(LOG, "Buy 37 button clicked.");
if (m37paid) {
Toast.makeText(getApplicationContext(), R.string.already_bought, Toast.LENGTH_LONG).show();
return;
}
Log.d(LOG, "launching purchase for 37");
String payload = "";
try {
mHelper.launchPurchaseFlow(this, SKU_W37, RC_REQUEST, mPurchaseFinishedListener, payload);
} catch (IabHelper.IabAsyncInProgressException e) {
Toast.makeText(getApplicationContext(), R.string.purchase_error, Toast.LENGTH_LONG).show();
}
}
public void onBuyAllButtonClicked (View arg0) {
Log.d(LOG, "Buy all button clicked.");
if (m32paid) {
Toast.makeText(getApplicationContext(), R.string.already_bought, Toast.LENGTH_LONG).show();
return;
}
Log.d(LOG, "launching purchase for all");
String payload = "";
try {
mHelper.launchPurchaseFlow(this, SKU_ALL, RC_REQUEST, mPurchaseFinishedListener, payload);
} catch (IabHelper.IabAsyncInProgressException e) {
Toast.makeText(getApplicationContext(), R.string.purchase_error, Toast.LENGTH_LONG).show();
}
}
我的mPurchaseFinishedListener：
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
Log.d(LOG, "Purchase finished: " + result + ", purchase: " + purchase);
SharedPreferences.Editor editor = getSharedPreferences("my_pref", MODE_PRIVATE).edit();
// if we were disposed of in the meantime, quit.
if (mHelper == null) return;
if (result.isFailure()) {
complain("Error purchasing: " + result);
return;
}
if (purchase.getSku().equals(SKU_W30)) {
editor.putBoolean("workout30", true);
editor.apply();
return;
}
if (purchase.getSku().equals(SKU_W31)) {
editor.putBoolean("workout31", true);
editor.apply();
return;
}
if (purchase.getSku().equals(SKU_W32)) {
editor.putBoolean("workout32", true);
editor.apply();
return;
}
if (purchase.getSku().equals(SKU_W37)) {
editor.putBoolean("workout37", true);
editor.apply();
return;
if(purchase.getSku().equals(SKU_ALL)) {
editor.putBoolean("workout31", true);
editor.putBoolean("workout32", true);
editor.putBoolean("workout37", true);
editor.apply();
return;
}
然后在数据的位置，我只需要一个if语句来检查布尔值：
xpandableListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
SharedPreferences pref = getApplicationContext().getSharedPreferences("my_pref", MODE_PRIVATE);
boolean w31 = pref.getBoolean("workout31", false);
boolean w32 = pref.getBoolean("workout32", false);
boolean w37 = pref.getBoolean("workout37", false);
if (groupPosition == 2) {
if(w31 == true) {
if (childPosition == 0) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
intent.putExtra("workout", "w31w1");
startActivity(intent);
}
if (childPosition == 1) {
Intent intent = new Intent(getApplicationContext(), WorkoutDaysActivity.class);
intent.putExtra("workout", "w31w2");
startActivity(intent);
}
}else Toast.makeText(getApplicationContext(), "Sorry, but you need to purchase these workouts from the menu.", Toast.LENGTH_LONG).show();
}
所有子项都具有与上面相同的代码，用w32和w37切换w31。
我已经购买了大部分商品以尝试削减代码但仍然明白了，但基本上发生的事情是之前添加了31和32，然后我使用了购买全部按钮，他们工作。但是我在稍后的更新中添加了37，我的理论是当它查询所有锻炼并看到它被购买时，布尔值会改变它。实际上，当我在可扩展列表视图中点击37时，我得到了需要购买的祝酒词，当我进入购买页面并点击“全部购买”时，我得知它已经购买了。
有人看到我的代码有什么问题吗？非常感谢，这造成了巨大的问题！
