下载图像我用这样的代码从URL下载图像:问题与URL
public static Bitmap downloadImage(String url) {
Bitmap bitmap = null;
InputStream in = null;
BufferedOutputStream out = null;
try {
in = new BufferedInputStream(new URL(url).openStream(), IO_BUFFER_SIZE);
final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
out = new BufferedOutputStream(dataStream, IO_BUFFER_SIZE);
copy(in, out);
out.flush();
final byte[] data = dataStream.toByteArray();
BitmapFactory.Options options = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,options);
} catch (IOException e) {
Log.e(TAG, "Could not load Bitmap from: " + url);
} finally {
closeStream(in);
closeStream(out);
}
return bitmap;
}
当我发送URL“http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009 /04/android_icon_256.png“它工作正常,但是当我使用”http://www.hospimedica.com/images/stories/articles/article_images/_CC/20110328%20-%20DJB146.gif“它返回我空。 这个URL有什么问题?
它不起作用。网址有问题,但我不知道究竟是什么 – shtkuh 2011-04-28 12:11:03
也许是因为URL中的空格? – shtkuh 2011-04-28 12:19:49
你会得到什么错误? – thoredge 2011-04-28 12:31:47
