I think what you are looking for is the <code>DownloadManager.COLUMN_TITLE</code>

Here is a link to the Android Documents: <a href="http://developer.android.com/reference/android/app/DownloadManager.html#COLUMN_TITLE" rel="nofollow">http://developer.android.com/reference/android/app/DownloadManager.html#COLUMN_TITLE</a>

And here is a tutorial that will explain more than just getting the title. It is for downloading an image from a URL and then displaying it in an application. Mighty useful I think, overall speaking.

blocks|key|439538|text|我想你应该把类似这样的东西放到你的if代码块中。用您的DownloadManager实例替换YOUR_DM。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|439539|Bundle+extras+=+intent.getExtras();

I think you want to put something like this inside your <code>if</code> block. Replace <code>YOUR_DM</code> with your DownloadManager instance.

<pre><code>Bundle extras = intent.getExtras();
DownloadManager.Query q = new DownloadManager.Query();
q.setFilterById(extras.getLong(DownloadManager.EXTRA_DOWNLOAD_ID));
Cursor c = YOUR_DM.query(q);

if (c.moveToFirst()) {
 int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));
 if (status == DownloadManager.STATUS_SUCCESSFUL) {
 // process download
 title = c.getString(c.getColumnIndex(DownloadManager.COLUMN_TITLE));
 // get other required data by changing the constant passed to getColumnIndex
 }
}
</code></pre>

blocks|key|221343|text|有一种更简单的方法来检索下载的文件URI，那就是使用getUriForDownloadedFile|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|221344|download_receiver+=+new+BroadcastReceiver()+{

There's a simpler way to retrieve the downloaded file URI, and that is with <code>getUriForDownloadedFile</code>:

<pre><code>download_receiver = new BroadcastReceiver() {
 @Override
 public void onReceive(Context context, Intent intent) {
 Bundle b = intent.getExtras();
 DownloadManager dm = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
 long file_id = b.getLong(DownloadManager.EXTRA_DOWNLOAD_ID);
 Uri uri = dm.getUriForDownloadedFile(downloaded_file_id);

 }
}
</code></pre>

I found this method <a href="https://stackoverflow.com/a/31275425/4562156">here</a> in a full description of how to use a BroadcastReceiver for handling DOWNLOAD_COMPLETE events.

In my app you can download some files. I used the Android <code>DownloadManager</code> class for downloading. After the download is completed, it should show me a message that the file was downloaded. The problem is, there could be 2,3 or 4 downloads at the same time. My <code>BroadcastReceiver</code> code looks like this:

<pre><code>receiver_complete = new BroadcastReceiver(){
 @Override
 public void onReceive(Context context, Intent intent) {
 String action = intent.getAction();
 if (action.equals(DownloadManager.ACTION_DOWNLOAD_COMPLETE) ){
 Toast.makeText(MainActivity.this, MainActivity.this.getString(R.string.download_finished, "Here should be the name", Toast.LENGTH_SHORT).show();
 }
 }
 };
</code></pre>

How can I get the current filename of the finished download?

Thank you very much.

在我的应用程序中，你可以下载一些文件。我使用Android的DownloadManager类进行下载。下载完成后，它应该会显示一条消息，告诉我文件已下载。问题是，同时可能有2,3或4次下载。我的BroadcastReceiver代码如下所示：receiver_complete = new BroadcastReceiv...
