我想在通过亚马逊进行的 inapppurchasing SamplepurchaseListener.java 的 onpurchaseresponse() 中使用共享偏好

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 class 中使用这个值。我该怎么做？请给我建议？

    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;

如果您只想从另一个 class 中检索值，为什么不直接从首选项中获取呢？像这样：

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

如果之前没有存储值，方法将return "false"。可能我没看懂你的问题。
