推荐答案
<一个href=\"http://developer.android.com/reference/android/app/DownloadManager.html#enqueue%28android.app.DownloadManager.Request%29\"><$c$c>DownloadManager#enqueue$c$c>返回长
重新presenting下载发生的 ID
。在一个变量保存长
。
DownloadManager#enqueue
returns a long
representing the id
of the download taking place. Save that long
in a variable.
然后,如果你需要取消下载,请拨打<一个href=\"http://developer.android.com/reference/android/app/DownloadManager.html#remove%28long...%29\"><$c$c>DownloadManager#remove()$c$c>在经过那么长。
Then, if you need to cancel the download, call DownloadManager#remove()
passing in that long.
例如:
//start a download
long id = downloadManager.enqueue(request);
//stop a download
downloadManager.remove(id);
