Android TextView添加超链接的方法示例

本文实例讲述了android textview添加超链接的方法。分享给大家供大家参考，具体如下：

public class link extends activity {
  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.link);
    // text1 shows the android:autolink property, which
    // automatically linkifies things like urls and phone numbers
    // found in the text. no java code is needed to make this
    // work.
    // text2 has links specified by putting <a> tags in the string
    // resource. by default these links will appear but not
    // respond to user input. to make them active, you need to
    // call setmovementmethod() on the textview object.
    textview t2 = (textview) findviewbyid(r.id.text2);
    t2.setmovementmethod(linkmovementmethod.getinstance());
    // text3 shows creating text with links from html in the java
    // code, rather than from a string resource. note that for a
    // fixed string, using a (localizable) resource as shown above
    // is usually a better way to go; this example is intended to
    // illustrate how you might display text that came from a
    // dynamic source (eg, the network).
    textview t3 = (textview) findviewbyid(r.id.text3);
    t3.settext(
      html.fromhtml(
        "<b>text3:</b> text with a " +
        "<a href=\"http://www.google.com\">link</a> " +
        "created in the java source code using html."));
    t3.setmovementmethod(linkmovementmethod.getinstance());
    // text4 illustrates constructing a styled string containing a
    // link without using html at all. again, for a fixed string
    // you should probably be using a string resource, not a
    // hardcoded value.
    spannablestring ss = new spannablestring(
      "text4: click here to dial the phone.");
    ss.setspan(new stylespan(typeface.bold), 0, 6,
          spanned.span_exclusive_exclusive);
    ss.setspan(new urlspan("tel:[phone]"), 13, 17,
          spanned.span_exclusive_exclusive);
    textview t4 = (textview) findviewbyid(r.id.text4);
    t4.settext(ss);
    t4.setmovementmethod(linkmovementmethod.getinstance());
  }
}
