使用app内置webview 打开TextView中的超链接
【法1】
/**
* 处理html文本超链接点击事件
* @param context
* @param tv
*/

tv.setMovementMethod(LinkMovementMethod.getInstance());

for (URLSpan url : urls) {

MyURLSpan myURLSpan =new MyURLSpan(url.getURL(), context);
style.setSpan(myURLSpan, sp.getSpanStart(url),
sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
}
tv.setText(style);
}
}

}
}
