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:4155551212"), 13, 17,                   Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);         TextView t4 = (TextView) findViewById(R.id.text4);        t4.setText(ss);        t4.setMovementMethod(LinkMovementMethod.getInstance());    }}
