使用Linkify查找和设置文本内的链接时，处理对TextView链接的单击

问题描述

我有一个TextView，其中填充了我从服务器获取的文本.我正在使用 Linkify 来处理所有链接搜索和在整个addLinks方法中需要的地方设置URLSpan.

i have a TextView filled with text which i get from a server. I'm using Linkify for handling all the link searching and for setting a URLSpan where needed throughout its addLinks method.

问题是单击链接时的默认行为是在浏览器中打开它，我想要的是获取被单击的链接并自行处理.

The problem is that the default behavior when clicking a link is opening it in a browser, what i want is to get the clicked link and handle it my self.

我没有看到Linkify的任何方法让我设置"OnClick"之类的东西...

I don't see any method of Linkify which let me set a "OnClick" or something...

感谢您的帮助:)

推荐答案

好，所以我终于设法将自己的"OnClickListener"设置为TextView的链接.我的解决方案是将Linkify复制到我的项目中，将其命名为CustomLinkify，然后更改其applyLink方法:

Ok so i finally managed to set my own "OnClickListener" to the TextView's links.My solution was to copy Linkify to my project, name it CustomLinkify and just change its applyLink method:

发件人:

private static final void applyLink(String url, int start, int end, Spannable text)
{
    URLSpan span = new URLSpan(url);

    text.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}

收件人:

private static final void applyLink(final String url, int start, int end, Spannable text)
{
    URLSpan span = new URLSpan(url)
    {
        @Override
        public void onClick(View widget)
        {
            _onLinkClickListener.onLinkClicked(url);
        }
    };

    text.setSpan(span, start, end, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}

_onLinkClickListener是新字段，由我在使用新的CustomLinkify之前设置.

Where _onLinkClickListener is a new field, set by me before using the new CustomLinkify.

我知道这不是一个非常优雅的解决方案，我更喜欢Google允许通过本机Linkify设置侦听器，但是对我来说，这比实现我自己的Spannable逻辑要好(如其他相关问题所建议).

I know its not a very elegant solution and i prefered google to allow setting a listener through the native Linkify, but, for me, this is better than implementing my own Spannable logics (as suggested in other related questions).

我相信Linkify代码，我想我会不时检查它是否有任何更改，如果是的话，我当然会用这些更改来更新CustomLinkify.

I trust the Linkify code and i guess i'll check from time to time to see if any changes made on it, if so, i'll of course update CustomLinkify with the changes.

希望这会对某人有所帮助.
