我使用DownloadManager类从服务器下载文件
这就是我正在做的事情
foreach
事情是当下载完成然后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
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);
}
请帮忙
答案 0 :(得分:5)
最后通过2行
修复了这个问题 request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
