推荐答案

这解决了我的问题。

@覆盖             公共布尔shouldOverrideUrlLoading（web视图查看，字符串URL）{                 布尔shouldOverride = FALSE;                 //我们只需要处理图像文件的请求，一切的web视图                 //可以处理正常                 如果（url.endsWith（。JPG））{                     shouldOverride = TRUE;                     乌里源= Uri.parse（URL）;                     //创建一个新的请求指向MP3网址                     DownloadManager.Request请求=新DownloadManager.Request（源）;                     //使用相同的文件名的目标                     文件destinationFile =新的文件（destinationDir，source.getLastPathSegment（））;                     request.setDestinationUri（Uri.fromFile（destinationFile））;                     //添加到经理                     manager.enqueue（要求）;                 }                 返回shouldOverride;             }

@Override public boolean shouldOverrideUrlLoading (WebView view, String url) { boolean shouldOverride = false; // We only want to handle requests for image files, everything else the webview // can handle normally if (url.endsWith(".jpg")) { shouldOverride = true; Uri source = Uri.parse(url); // Make a new request pointing to the mp3 url DownloadManager.Request request = new DownloadManager.Request(source); // Use the same file name for the destination File destinationFile = new File (destinationDir, source.getLastPathSegment()); request.setDestinationUri(Uri.fromFile(destinationFile)); // Add it to the manager manager.enqueue(request); } return shouldOverride; }

请一定要添加的权限下载管理器，SD读取，SD写！

make sure to add permissions for download manager, SD read, SD write!
