最新代码，请查看链接形式 github https://github.com/boiledwater/spanned
message.setSpan(span, start, end, flags);
你需要删除原点跨度在设置新的跨度之前。

ClickableSpan 的 onClick() 不适用于 URLSpan？ https://stackoverflow.com/questions/9164190/the-onclick-of-clickablespan-is-not-working-for-urlspan
EDIT
您可以捕捉任何跨度单击事件 by extends LinkMovementMethod

编辑“android 开发者”
这是更好的添加方式Handler财产为链接移动方法Ext class.
您可以捕获作为 Message 对象传递的所有 Spanned。
onTouchEvent 方法中的代码片段：
Message message = Handler.obtainMessage();
message.obj = buffer.getSpans(off, off, Spanned.class);//get all spanned
message.what = 111;//which value ,it is up to you
message.sendToTarget(); //send message to you target handler
您可以在处理程序类中处理预期的跨越。也许这是一种灵活的处理方式。
希望对您有所帮助。
上面的文本视图文本是<a href='/a'>aaaa</a>123456<a href='/b'>bbbb</b>7890
我了解您的要求：
点击“aaaa”，你想要它s href value '/a', click 'bbbb',get its href '/b';不触发在网络浏览器中打开的默认操作。
如果我的理解是正确的，你可以这样做：
- 为textview等设置LinkMovementMethod：
textview.setMovementMethod(LinkMovementMethodExt.getInstance(handler, URLSpan.class));
- 获取兴趣跨度，这里是URLSpan。
在你的处理程序中处理消息方法，你可以这样做：
private Handler handler = new Handler() {
public void handleMessage(Message msg) {
int what = msg.what;
if (what == 100) {
Object[] spans = (Object[])msg.obj;
for (Object span : spans) {
if (span instanceof URLSpan) {
System.out.println(((URLSpan) span).getURL());
}
}
}
};
};

主要活动 has color您可以根据需要指定颜色值的属性。
怎么做？
