Android TextView通过Spannable识别超链接、邮箱、电话

来源：互联网发布：联合国统计署数据库编辑：程序博客网时间：2024/05/22 00:25

现在有好多应用都能识别电话号码、邮箱、超链接，点击电话号码可以直接调用系统电话进行拨打，点击邮箱则调用系统邮箱或者第三方的邮箱，点击超链接则会进入浏览器，方便操作。现在经过简单的封装来实现这三个功能。

在MainActivity中调用，只需一句话搞定

LinkifySpannableUtils.getInstance().setSpan(MainActivity.this,自己写的TextView控件);

这个主要适配6.0,获取权限后的回调
