how to create textview link without underscore in

问题:

i came into this wired situation, my code is as follow

LinearLayout ll = new LinearLayout(this);
TextView tv = new TextView(this);
ll.addView(tv);
tv.setText(Html.fromHtml("<a STYLE=\"text-decoration:none;\" href=\"" 
        + StringEscapeUtils.escapeJava(elem.getChildText("newsLink")) + "\">" 
                + StringEscapeUtils.escapeJava(elem.getChildText("Title")) + "</a>"));
tv.setTextColor(Color.BLACK);

but the style="text-decoration:none" and tv.setTextColor(color.black)both not working, the link is still in blue with underscore, any hints on why they're not working? Thanks!

回答1:

you can try this. such as

String content = "your <a href='http://some.url'>html</a> content";

Here is a concise way to remove underlines from hyperlinks:

Spannable s = (Spannable) Html.fromHtml(content);
for (URLSpan u: s.getSpans(0, s.length(), URLSpan.class)) {
    s.setSpan(new UnderlineSpan() {
        public void updateDrawState(TextPaint tp) {
            tp.setUnderlineText(false);
        }
    }, s.getSpanStart(u), s.getSpanEnd(u), 0);
}
tv.setText(s);

You can use Spannable and URLSpan here to remove hyperlink underline from your code

First of all make your anchor tag text into Spannable

Spannable spannedText = Spannable.Factory.getInstance().newSpannable(
            Html.fromHtml(webLinkText));

Create new class URLSpanNoUnderline and extend it with URLSpan and override updateDrawState method. in that method you can set setUnderlineText to false

then use this method you can remove your link

public static Spannable removeUnderlines(Spannable p_Text) {  
       URLSpan[] spans = p_Text.getSpans(0, p_Text.length(), URLSpan.class);  
       for (URLSpan span : spans) {  
            int start = p_Text.getSpanStart(span);  
            int end = p_Text.getSpanEnd(span);  
            p_Text.removeSpan(span);  
            span = new URLSpanNoUnderline(span.getURL());  
            p_Text.setSpan(span, start, end, 0);  
       }  
       return p_Text;  
  }
