我在服务中有一个 AsyncTask，它试图将 ArrayList 传递给我的 Activity。

ArrayList<Malware> fetch = new ArrayList<Malware>();
        @Override
        protected void onPostExecute(Void result) {

                Intent d = new Intent();
                d.setAction(COMPLETED_INTENT);
                d.putExtra("CurrentProgress", "completed");
                d.putExtra("MalwareArray", fetch);
                sendBroadcast(d);
        }

我在尝试将数组列表广播到活动时遇到错误。

你需要让你的对象实现 parcelable 接口，这样你就可以通过一个意图来传递它。

这是实现此功能的一个很好的示例：

Android Parcelable -- RetailerOrderActivity.java 返回 null
