android - 从 Android 路径中带有空格的 URL 下载图像

Question

我想从路径下载图片。这是我的代码:

String urlString = "http://www.hospimedica.com/images/stories/articles/article_images/_CC/20110328 - DJB146.gif";
url = new URL(urlString.replaceAll(" ", "%20"));
bm = BitmapFactory.decodeStream(url.openConnection().getInputStream());

但它在 bm 中返回 null。有什么想法可以让这段代码正常工作吗？

试试 UrlEncoder。

String urlString = URLEncoder.encode("http://www.hospimedica.com/images/stories/articles/article_images/_CC/20110328 - DJB146.gif");
url = new URL(urlString);
bm = BitmapFactory.decodeStream(url.openConnection().getInputStream());
