android– 使用下载管理器下载文件

概述我正在使用DownloadManager类从服务器下载文件这就是我在做的事情publicvoiddownloadPdf(Stringurl,Stringsem,Stringtitle,Stringbranch){UriDownload_Uri=Uri.parse(url);DownloadManager.Requestrequest=newDownloadManager.Request(Download_Uri

我正在使用DownloadManager类从服务器下载文件

这就是我在做的事情

public voID downloadpdf(String url, String sem, String Title, String branch) {    Uri Download_Uri = Uri.parse(url);    DownloadManager.Request request = new DownloadManager.Request(Download_Uri);    //Restrict the types of networks over which this download may proceed.    request.setAllowednetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);    //Set whether this download may proceed over a roaming connection.    request.setAllowedOverRoaming(false);    //Set the Title of this download, to be displayed in notifications (if enabled).    request.setTitle("Downloading");    //Set a description of this download, to be displayed in notifications (if enabled)    request.setDescription("Downloading file");    //Set the local destination for the downloaded file to a path within the application's external files directory    request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, Title + "_" + branch + "_" + sem + "Year" + System.currentTimeMillis() + ".pdf");    //Enqueue a new download and same the referenceID    downloadReference = downloadManager.enqueue(request);}

事情是当下载完成后,如果用户点击通知它应该打开该文件我应该在此代码中做什么

 broadcastReceiver onNotificationClick = new broadcastReceiver() {    public voID onReceive(Context ctxt, Intent intent) {    }};

请帮忙

解决方法:

最后通过2行修复了这个问题

 request.allowScanningByMediaScanner();request.setNotificationVisibility(DownloadManager.Request.VISIBIliTY_VISIBLE_NOTIFY_COMPLETED);
