Question

当案例成功时，我想编辑变量值，然后我想在我的项目的其他类中使用此值。我该怎么做？请建议我？

    switch (status) {
    case SUCCESSFUL:


        SamplePurchasingListener.this.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                // TODO Auto-generated method stub
                SharedPreferences.Editor editor = getSharedPreferences(MY_PREFS_NAME, MODE_WORLD_READABLE).edit();
                editor.putBoolean("PREMIUM", true); // Storing boolean - true/false
                editor.commit();
            }
        });

        final Receipt receipt = response.getReceipt();
        iapManager.setAmazonUserId(response.getUserData().getUserId(), response.getUserData().getMarketplace());
        Log.d(TAG, "onPurchaseResponse: receipt json:" + receipt.toJSON());
        iapManager.handleReceipt(response.getRequestId().toString(), receipt, response.getUserData());
        iapManager.refreshLevel2Availability();

     break;
    case ALREADY_PURCHASED:


        Log.i(TAG,
              "onPurchaseResponse: already purchased, you should verify the entitlement purchase on your side and make sure the purchase was granted to customer");

        break;

如果您只想从其他课程中检索价值，为什么不从偏好中获取价值？像这样：

SharedPreferences sp = getSharedPreferences(MY_PREFS_NAME, MODE_WORLD_READABLE);
boolean premium = sp.getBoolean("PREMIUM", false);
if(premium) { ...

如果之前没有存储过值，则方法将返回＆＃34; false＆＃34;。也许我还没有理解你的问题。

我想通过amazon在inapppurchasing的SamplepurchaseListener.java的onpurchaseresponse（）中使用共享首选项
