Answer 1

集DownloadListener到您的WebView。

例子：

webview.setDownloadListener(new DownloadListener() { 
     @Override 
     public void onDownloadStart(String url, String userAgent, 
       String contentDisposition, String mimetype, 
       long contentLength) { 
      // handle download, here we use brower to download, also you can try other approach. 
      Uri uri = Uri.parse(url); 
      Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
      startActivity(intent); 
     } 
    }); 

或者

webview.setDownloadListener(new DownloadListener() { 
     public void onDownloadStart(String url, String userAgent, 
       String contentDisposition, String mimetype, 
       long contentLength) { 
        Request request = new Request(
          Uri.parse(url)); 
        request.allowScanningByMediaScanner(); 
        request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); 
        request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "download"); 
        DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE); 
        dm.enqueue(request);   

     } 
    });
