blocks|key|2270710|text|我没有太多使用Linkify的经验。到目前为止，我想要做的就是将文本中的urls变成链接，这是由不同版本的addLinks自动处理的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2270711|但是，您在"Android“上用于匹配的正则表达式可以更改为仅匹配通过调整正则表达式开始字符串的正则表达式：|2270712|Pattern+pattern+=+Pattern.compile("%5EAndroid");|code-block|syntax|javascript|2270713|注意添加了“%5E”。这告诉正则表达式匹配器在开始字符串时只匹配模式'Android‘。如果这可以和你的字符串一起工作，那就太好了。如果在其他情况下，您想要链接的单词不在行首，那么您将需要更多地探索正则表达式。我推荐这个站点来学习更多的regular-expressions.info|2270714|entityMap|0|LINK|mutability|MUTABLE|url|http://www.regular-expressions.info/tutorial.html^0|1H|8|0|0|0|38|O|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Z|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|10|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|11|8|@]|D|@$9|12|A|13|1|14]]|E|$]]|$1|O|3|-4|5|6|7|15|8|@]|D|@]|E|$]]]|P|$Q|$5|R|S|T|E|$U|V]]]]

I don't have much experience with Linkify. So far all I have wanted to do is make urls in the text into links which is handled automatically by a different version of <code>addLinks</code>.

However the regular expression you are using to match on "Android" can be changed to only match the one that starts the string by tweaking your regular expression:

<pre><code>Pattern pattern = Pattern.compile("^Android");
</code></pre>

Notice the addition of '^'. This tells the regular expression matcher to only match the pattern 'Android' when it starts the string. If that will work with your strings then great. If you have other cases were the word you want to link is not at the beginning of the line you will need to explore regular expressions some more. I recommend this site to learn more <a href="http://www.regular-expressions.info/tutorial.html" rel="noreferrer">regular-expressions.info</a>

If you want to open all the urls which contains in text then you can do this..

<pre><code> TextView textview=(TextView)findViewById(R.id.text);

 textview.setText("Android....Update from android...www.android.com");
 Linkify.addLinks(textview, Linkify.WEB_URLS);
 textview.setMovementMethod(LinkMovementMethod.getInstance());

It may work for all urls.

blocks|key|1753489|text|我创建了一个静态方法，简单地实现了这一点：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1753490|/**

I created a static method that does this simply:

<pre><code>/**
 * Add a link to the TextView which is given.
 * 
 * @param textView the field containing the text
 * @param patternToMatch a regex pattern to put a link around
 * @param link the link to add
 */
public static void addLink(TextView textView, String patternToMatch,
 final String link) {
 Linkify.TransformFilter filter = new Linkify.TransformFilter() {
 @Override public String transformUrl(Matcher match, String url) {
 return link;
 }
 };
 Linkify.addLinks(textView, Pattern.compile(patternToMatch), null, null,
 filter);
}
</code></pre>

And the OP could use it simply:

<pre><code>addLink(text, "^Android", "http://www.android.com");
</code></pre>

Here from Shawns answer and SpunkerBaba's comment I've come out with this helper class. This stops the issue of the double appending of what you are changing being added to your url.

<pre><code>package com.your.package;

public class Linkify {

 /**
 * @param textView
 * textView who's text you want to change
 * @param linkThis
 * a regex of what text to turn into a link
 * @param toThis
 * the url you want to send them to
 */
 public static void addLinks(TextView textView, String linkThis, String toThis) {
 Pattern pattern = Pattern.compile(linkThis);
 String scheme = toThis;
 android.text.util.Linkify.addLinks(textView, pattern, scheme, new MatchFilter() {
 @Override
 public boolean acceptMatch(CharSequence s, int start, int end) {
 return true;
 }
 }, new TransformFilter() {

 @Override
 public String transformUrl(Matcher match, String url) {
 return "";
 }
 });
 }

}
</code></pre>

Useage:

<pre><code> Linkify.addLinks(profileTextView, "BlundellApps.com", "http://www.BlundellApps.com");
</code></pre>

blocks|key|1753534|text|最简单的方法是将autoLink放在XML布局中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1753535|++android:autoLink="web"+|code-block|syntax|javascript|1753536|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

The easy way is put autoLink in XML layout.

<pre><code> android:autoLink="web"

blocks|key|4383388|text|问题解决了。第一个问题的解决方案是Ian+Leslie提供的答案。第二个问题的解决方案是，因为Linkify.addLinks接口的follows.The行为是这样的，它将您想要链接的字符串附加到url的末尾。对于Android，你需要将文本"Android“和"www.android.com”链接起来。最后的网址是"www.android.comAndroid“，这不是我使用的needed.So|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4383389|public+static+final+void+addLinks+(TextView+text,+Pattern+p,+String+scheme,+Linkify.MatchFilter+matchFilter,+Linkify.TransformFilter+transformFilter)

public+final+String+transformUrl(final+Matcher+match,+String+url)+{+
return+"";+
}+};+|code-block|syntax|javascript|4383390|transformFilter接口返回空字符串。所以我最后的网址是"www.android.com“|4383391|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Problem solved. Solution to the first problem is the answer provided by Ian Leslie. Solution to the second problem is as follows.The behavior of API "Linkify.addLinks" is such that, it appends the string that you want to linkify to the end of the url. For ex..if you want to linkify text "Android" with "www.android.com". The final URL is "www.android.comAndroid" which is not what I needed.So i used 

<pre><code>public static final void addLinks (TextView text, Pattern p, String scheme, Linkify.MatchFilter matchFilter, Linkify.TransformFilter transformFilter)
TransformFilter transformFilter = new TransformFilter() {
public final String transformUrl(final Matcher match, String url) { 
return ""; 
} }; 
</code></pre>

The api transformFilter return a null string. So my final url is "www.android.com"

I think what you really need is something as simple as:

<pre><code>final TextView textView = ((BodyViewHolder) holder).textView;
textView.setText(text);
Linkify.addLinks(textView, Linkify.WEB_URLS); // I would do this only during view creation, btw.
</code></pre>

You're tracking an URL specifically. Some people suggest using Linkigy.ALL, but you don't want this:

<pre><code>public static final int ALL = WEB_URLS | EMAIL_ADDRESSES | PHONE_NUMBERS | MAP_ADDRESSES;
</code></pre>

Also, other people are suggesting adding:

<pre><code>textview.setMovementMethod(LinkMovementMethod.getInstance());
</code></pre>

after adding the link rules, but <code>addLinks</code> already does that in its insides ;-)

Cheers!

blocks|key|2270918|text|对于带有lambda表达式的Koltin，应该是这样的|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2270919|val+pattern+=+Pattern.compile(link.title)
Linkify.addLinks(view,+pattern,+null,+null,+{+matcher,+url+->+link.href+})|code-block|syntax|javascript|2270920|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

For Koltin with lambda expression, it would be like this

<pre><code>val pattern = Pattern.compile(link.title)
Linkify.addLinks(view, pattern, null, null, { matcher, url -&gt; link.href })
</code></pre>

I have textview which I need to linkify. Here's what I am doing..

<pre><code>TextView text = (TextView) view.findViewById(R.id.name);
text.setText("Android...Update from Android");
Pattern pattern = Pattern.compile("Android");
String scheme = "www.android.com";
Linkify.addLinks(text, pattern, scheme);
</code></pre>

The text-view is displayed correctly with the text "Android...Update from Android", but I am facing two problems.

1) My text string has two instances of the string "Android". So, both the text are linkified. I want only the first occurrence to be linkified. How should I go about it?

2) When I click the linkfy text, it opens the browser, but the URL is weird. The url it tries to open is "www.comandroid". I don't know whats going wrong here. The text "android" in the URL is being replaced. Am I doing something wrong when Linknifying the text.

Any help will be highly appreciated.
