往SystemUI添加进度条

1、定义一个进度条的布局文件

    res/layout/notificat_progress.xml

2、用RemoteViews显示布局

    RemoteViews view = new RemoteViews(getPackageName(), R.layout.notificat_progress);

3、用Notification发布通知

    Notification    notification =new Notification     (通知图标,通知信息,0);

4、实际代码

    RemoteViews view = null;

    Notification notification;

    Intent intent= new Intent();;

    PendingIntent pendingIntent;

    pendingIntent = PendingIntent.getActivity(Gallery.this, 0, intent, 0);

    notification = new Notification (R.drawable.download_current,getResources().getString(R.string.download_massege),0);

    view = new RemoteViews(getPackageName(), R.layout.notificat_progress);

    view.setProgressBar(R.id.progress, 100, 0, false);//设置进度条

    view.setTextViewText(R.id.percent,   0 + "%");     //设置显示百分比

    notification.defaults = Notification.FLAG_ONLY_ALERT_ONCE;

    notification.icon = R.drawable.download_current;//状态栏显示图标

    notification.contentView = view;

    notification.contentIntent = pendingIntent;

    notificationManager.notify(0, notification); //发布通知
