Android TextView添加超链接的方法示例

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());
  }
