本文介绍了一个在Android应用中实现自定义通知栏进度条的例子。通过创建Notification并使用RemoteViews更新进度条的状态，展示了如何在后台线程中更新UI组件，并确保主线程不被阻塞。此外还介绍了如何设置点击通知后的跳转行为。

private static final int PROGRESS = 0x1;
    private static final int MAX_PROGRESS = 100;

    private int mProgressStatus = 10;

    private Handler mHandler = new Handler();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.twolayout);

        NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

int icon = R.drawable.icon; //通知图标

CharSequence tickerText = "Hello"; //状态栏显示的通知文本提示

long when = System.currentTimeMillis(); //通知产生的时间，会在通知信息里显示

//用上面的属性初始化Nofification

        Notification notification = new Notification(icon,tickerText,when);



        final RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification_layout);
        contentView.setProgressBar(R.id.progress_bar, MAX_PROGRESS, mProgressStatus, false);

        notification.contentView = contentView;


        // Start file upload in a background thread
        new Thread(new Runnable() {
            public void run() {
                while (mProgressStatus < MAX_PROGRESS) {
                    mProgressStatus += mProgressStatus;

                    // Update the progress bar
                    mHandler.post(new Runnable() {
                        public void run() {
                            contentView.setProgressBar(R.id.progress_bar, MAX_PROGRESS, mProgressStatus, false);
                        }
                    });
                }
            }
        }).start();


        Intent notificationIntent = new Intent(this,TestTwoDScrollView.class);
