android - 如何在Android中对URL进行编码，如下所示？

我想在网址下方转换

至

https://sdcude.pdakmdda.at/sdtddio/img/thumbnails/original/%C3%96ffnungszeiten%20Test-638.jpg

编码后我需要以上结果。我不知道上面的网址使用哪种编码。

String newurl=URLEncoder.encode(url,"UTF-8");

转换后，我使用UTF-8到达了以下网址

[https％3A％2F％2Fsddde.psdfma.co％2Fstudio％2Fimg％2Fthumbnails％2Foriginal％2F％C3％96ffnungszeiten + Test-638.jpg] [2]

最佳答案

只是因为网址中出现空格Ravi Thapliyal答案不正确，否则是正确的

下面对我来说工作

String ALLOWED_URI_CHARS = "@#&=*+-_ .,:!?()/~'%";
                    String spaceurl = Uri.encode(f_url[0], ALLOWED_URI_CHARS);
                    String newurl=spaceurl.replaceAll(" ", "%20");
