我正在使用DownloadManager类从服务器下载文件

I am downloading files from server using DownloadManager class

这是我在做什么

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); }

下载完成后，如果用户单击通知，它将打开该文件，我应该在这段代码中做什么

thing is when download is complete if then user clicks on notification it should open that file what should i do in this code

BroadcastReceiver onNotificationClick = new BroadcastReceiver() { public void onReceive(Context ctxt, Intent intent) { } };

请帮助

推荐答案

最后只用2行就解决了

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