                问题描述

                我正在尝试将文件从网络保存到我的 Android 设备,但我不知道该怎么做.URL 地址会打开一个空白页面和一个弹出下载框,其中包含我要下载的文件,以便我可以选择保存位置.

                I am trying to save a file from the web to my Android device, but I do not know how to do it. The URL address opens a blank page and a popup download box with the file that I want to download so I can choose where to save it.

                我的问题是我不知道如何管理该框以下载文件.我不想下载该页面上显示的内容,因为该页面是空白的.所以我不能使用这个代码:

                My problem is that I do not know how to manage that box in order to download the file. It is not like I want to download something that is shown on that page because the page is blank. So I cannot use this code :

                         Context context = thisClass.this;
                         Drawable image = ImageOperations(context,
                          "http://android.okhelp.cz/images/adictionary/ad_4.png"
                          ,"image.jpg");
                         ImageView imgView;
                         imgView = (ImageView)findViewById(R.id.idImageView);
                         imgView.setImageDrawable(image);
                
                private Drawable ImageOperations(Context ctx, String url, String saveFilename) {
                    try {
                        InputStream is = (InputStream) this.fetch(url);
                        Drawable d = Drawable.createFromStream(is, "src");
                        return d;
                    } catch (MalformedURLException e) {
                        e.printStackTrace();
                        return null;
                    } catch (IOException e) {
                        e.printStackTrace();
                        return null;
                    }
                }
                
                public Object fetch(String address) throws MalformedURLException,IOException {
                    URL url = new URL(address);
                    Object content = url.getContent();
                    return content;
                }
                

                如果有人能指出从哪里开始寻找或给我一个解决方案,我将不胜感激.

                I would be grateful if someone could point me where to start looking or gave me a solution.

                推荐答案

                我解决了!

                           File card2= Environment.getExternalStorageDirectory();
                           File dir2= new File (card2.getAbsolutePath()+"/MyFiles");
                            dir2.mkdirs();
                           new DefaultHttpClient().execute(new HttpGet(your_url_here-this_is_a_string)).getEntity().writeTo(
                            new FileOutputStream(new File(dir2,your_file_on_sdcard-this_is_string)));
                

                这也被 try/catch 包围.并记得在地址前插入协议,否则将不起作用!希望对您有所帮助!

                This is also surrounded by try/catch. And remember to insert the protocol before the address or it won't work! Hope it helps!
