在Android中显示图片，并在线显示文件名中的空格

问题描述

我需要在我的android应用程序中显示图像.问题是我想从网上某个地方获取此图像.网址类似:

I need to display an image in my android application. The problem is I want to get this image from somewhere online. The URL is like:

如您所见，图像名称中包含一些空格.每次执行代码时，都会显示FileNotFound异常.并没有任何反应.

As you see the image name containing some spaces in it. Every time I execute my code this will show me exception of FileNotFound. and nothing happens.

以下是我的代码

String imagePathCon = "hello world image.png";
String imagePath = "http://www.mydomain.com/" + imagePathCon;
try {
  URL url;
  url = new URL(imagePath);

  // url = new URL("http://www.azuma-kinba.com/wp-content/uploads/2012/05/Android-Make-Google-Loss-in-2010.png");

  InputStream content = (InputStream)url.getContent();
  Drawable d = Drawable.createFromStream(content , "src");
  im.setImageDrawable(d);

 } catch (MalformedURLException e) {
            e.printStackTrace();
 } catch (IOException e) {
            e.printStackTrace();
 }

我曾经用"+"代替空格，但是什么也没发生.

I use to replace space with "+" but nothing happens.

推荐答案

这将起作用.

String imagePathCon = "hello world image.png";
imagePathCon=imagePathCon.replaceAll(" ", "%20");

String imagePath = "http://www.mydomain.com/" + imagePathCon;
