我要像做
 单击＆lt; A HREF ='www.google.com'＆GT;此处＆lt; / A＆GT;

在机器人。我尝试使用以下内容：

in android. I tried using the following:

TextView sponsoredlink = new TextView(this);

                sponsoredlink.setText("Click Here");

                Pattern pattern =Pattern.compile("Here");

                String link = "www.google.com";

                Linkify.addLinks(sponsoredlink, pattern, link);

但我刚刚结束了一个链接www.google.comhere [原文]

but i just end up with a link to www.google.comhere [sic]

推荐答案

只是为了回答我的问题，我发现变换滤镜教程，它适用于我自己的目的：

Just to answer my own question, I found a tutorial on transform filters and adapted it to my own ends:

TextView sponsoredlink = new TextView(this);
                sponsoredlink.setId(R.id.details_sponsoredlink);
                sponsoredlink.setText("Click Here");

                TransformFilter mentionFilter = new TransformFilter() {
                    public final String transformUrl(final Matcher match, String url) {
                        return new String("http://www.google.com");
                    }
                };

                // Match @mentions and capture just the username portion of the text.
                Pattern pattern = Pattern.compile(".");
                String scheme = "";
                Linkify.addLinks(sponsoredlink, pattern, scheme, null, mentionFilter);

我决定把整个文本进入最后一个大的环节，所以我做匹配整个文本的模式。

I decided I wanted to turn the whole text into one big link in the end, so I did a pattern that matched the whole text.

然后我创建了一个变换滤波器刚刚忽略不管你给它，并返回我想带人到网址

Then I created a transform filter which just ignores whatever you give it and returns the URL I wanted to take people to

该计划也必须是空串，所以没事就末尾添加可获得

The scheme also has to be the empty string so nothing gets added on the end

最后，我用linkify把它一起

Finally I used linkify to put it all together
