安卓：Linkify的TextView [英] Android: Linkify TextView

问题描述

我有TextView的，我需要linkify。下面是我在做什么。

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

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);

文本视图是正确地从Android的安卓...更新的文字显示，但我面临两个问题。

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

1）我的文本字符串的字符串机器人的两个实例。因此，无论是文字的linkified。我想只有第一次出现被linkified。我应该怎么做呢？

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）当我点击linkfy文本，它会打开浏览器，但是URL是怪异。它试图打开URL是www.comandroid。我不知道怎么回事错在这里做。在URL文本机器人将被替换。我是不是做错了什么Linknifying的文本时。

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.

任何帮助将是非常美联社preciated。

Any help will be highly appreciated.

推荐答案

我创造，这是否只是一个静态方法：

I created a static method that does this simply:

/**
 * 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);
}

和运能利用它简单：

And the OP could use it simply:

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