Android 拦截TextView中超链接点击事件

Android 拦截TextView中超链接的点击事件

---

1.在xml中为TextView添加autoLink属性

<TextView
    ...
    android:autoLink = "web"
    ... />

2.

private void setLinkClickable(final SpannableStringBuilder clickableHtmlBuilder, final URLSpan urlSpan) {
    int start = clickableHtmlBuilder.getSpanStart(urlSpan);
    int end = clickableHtmlBuilder.getSpanEnd(urlSpan);
    int flags = clickableHtmlBuilder.getSpanFlags(urlSpan);
    ClickableSpan clickableSpan = new ClickableSpan() {
        @Override
        public void onClick(View widget) {
            String originUrl = urlSpan.getURL();//获取url地址
            //do something
            ...
        }
    };
    clickableHtmlBuilder.setSpan(clickableSpan, start, end, flags);
}

private CharSequence getClickableHtml(Spanned spannedHtml) {
    SpannableStringBuilder clickableHtmlBuilder = new SpannableStringBuilder(spannedHtml);
    URLSpan[] urls = clickableHtmlBuilder.getSpans(0, spannedHtml.length(), URLSpan.class);
    for (final URLSpan span : urls){
        setLinkClickable(clickableHtmlBuilder, span);
    }
    return clickableHtmlBuilder;
}

3.

String urlText;
Spanned spanned = Html.fromHtml(urlText);
textView.setText(getClickableHtml(spanned));
textView.setMovementMethod(LinkMovementMethod.getInstance());
