Question

我一直在开发一个Android RSS阅读器。我想从RSS提要中获取图像并将它们与RSS标题一起列出。我已经解析并从“标题”和“描述”标签中提取数据。可以告诉我任何人如何从“描述”的“src”属性下面获取图像URL？

Answer 1

首先，在AsyncTask中进行解析。在此任务中，您只需以加载的HTML / XML格式下载图像。

在后台加载URL时，您可以调用以下例程：

private Bitmap getImageFromURL(URL imgUrl){
        Bitmap bmp = null;

        try {
            HttpURLConnection conn= (HttpURLConnection)imgUrl.openConnection();
            conn.setDoInput(true);
            conn.connect();
            InputStream is = conn.getInputStream();

            bmp = BitmapFactory.decodeStream(is);
       } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
       }
       return bmp;  
    }

我找到了解决方案......

                        News news=new News();    

                        String img  = news.Description[i];
                        String cleanUp = img.substring(0, img.indexOf(">")+1);
                        img = img.substring(img.indexOf("src=") + 5);
                        int indexOf = img.indexOf("'");
                            if (indexOf==-1){
                            indexOf = img.indexOf("\"");
                           }
                        img = img.substring(0, indexOf);
                        news.image[i]=img;
