使用app内置webview 打开TextView中的超链接

【法1】

/**

* @param tv

*/

public void textHtmlClick(Context context, TextView tv) {

tv.setMovementMethod(LinkMovementMethod.getInstance());

    CharSequence text = tv.getText();

        style.clearSpans();// should clear old spans

        for (URLSpan url : urls) {

            MyURLSpan myURLSpan =new MyURLSpan(url.getURL(), context);

            style.setSpan(myURLSpan, sp.getSpanStart(url),

                    sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
