ss.setSpan(clickableSpan, 13, 25, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
这将使

可在我的示例字符串中单击。您可以根据需要使用normal color
、touchColor
和pressedColor

如何设置文本视图的超链接?Linkify或Html.fromHtml()您将需要使用spannableStringtouchableSpan@MeliX:我使用Html.fromHtml()@karandeep singh:你能提供详细信息吗?谢谢karandeep singh!我在字符串中使用html标记(如粗体、斜体、颜色,还有“a href”)。查看您的解决方案,我必须将“a href”-链接转换为setspan调用。其他html标签呢?
