I don't know what your code looks like, so I don't know what you need to modify, butI did some searching through the documentation. I found some stuff on <a href="http://developer.android.com/intl/de/guide/topics/ui/notifiers/notifications.html" rel="noreferrer">Notifications</a>, <a href="http://developer.android.com/intl/de/reference/android/widget/ProgressBar.html" rel="noreferrer">ProgressBars</a>, and <a href="http://developer.android.com/intl/de/reference/android/widget/RemoteViews.html" rel="noreferrer">RemoteViews</a>.

Specifically, in RemoveView, you can update the Progress bar. So combining some of the example code in each link, I get something like this:

<pre><code>public class MyActivity extends Activity {
 private static final int PROGRESS = 0x1;
 private static final int MAX_PROGRESS = 100;

 private int mProgressStatus = 0;

 private Handler mHandler = new Handler();

 protected void onCreate(Bundle icicle) {
 super.onCreate(icicle);

 //define Notification
 //...

 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 &lt; MAX_PROGRESS) {
 mProgressStatus = doWork();

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

blocks|key|1055256|text|要从RemoteView中删除ProgressBar，请使用以下代码:-|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1055257|+remoteViews.setViewVisibility(R.id.progressBar,+View.INVISIBLE);|code-block|syntax|javascript|1055258|你也可以使用View.GONE，但那会让安卓填补空白。|offset|length|style|CODE|1055259|entityMap^0|0|0|6|9|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

To remove a ProgressBar from RemoteView use the following code :-

<pre><code> remoteViews.setViewVisibility(R.id.progressBar, View.INVISIBLE);
</code></pre>

You can also use <code>View.GONE</code> but that will make android to fill empty space.

I would like to put a progress bar in the notification bar. The idea is showing the progress bar while the program uploads a file to a server. Everything else is ok, but I can not figure out how to refresh the progress bar inside the notification. Does anybody knows any pattern to play with? I mean, where I should refresh the progress bar, in a service or activity and so.

Refresh progress bar in notification bar

服务器

我想在通知栏中放置一个进度条。这个想法是在程序将文件上传到服务器时显示进度条。其他一切正常，但我不知道如何刷新通知内的进度条。有谁知道什么模式可以玩吗？我的意思是，我应该在哪里刷新进度条，在服务或活动中等等。
