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