submit.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    mNotifyManager =
                            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                    mBuilder = new NotificationCompat.Builder(this);
                    mBuilder.setContentTitle("Picture Download")
                        .setContentText("Download in progress")
                        .setSmallIcon(R.drawable.ic_notification);
                    // Start a lengthy operation in a background thread
                    new Thread(
                        new Runnable() {
                            @Override
                            public void run() {
                                int incr;
                                // Do the "lengthy" operation 20 times
                                for (incr = 0; incr <= 100; incr+=5) {
                                        // Sets the progress indicator to a max value, the
                                        // current completion percentage, and "determinate"
                                        // state
                                        mBuilder.setProgress(100, incr, false);
                                        // Displays the progress bar for the first time.
                                        mNotifyManager.notify(0, mBuilder.build());
                                            // Sleeps the thread, simulating an operation
                                            // that takes time
                                            try {
                                                // Sleep for 5 seconds
                                                Thread.sleep(5*1000);
                                            } catch (InterruptedException e) {
                                                Log.d(TAG, "sleep failure");
                                            }
                                }
                                // When the loop is finished, updates the notification
                                mBuilder.setContentText("Download complete")
                                // Removes the progress bar
                                        .setProgress(0,0,false);
                                mNotifyManager.notify(ID, mBuilder.build());
                            }
                        }
                    // Starts the thread by calling the run() method in its Runnable
                    ).start();
                }
            });

你应该改变这个

 mBuilder = new NotificationCompat.Builder(this);

到

 mBuilder = new NotificationCompat.Builder(youractivity.this);

您需要传递当前的Context 来创建mBuilder 对象。
