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()); } }

希望本文所述对大家Android程序设计有所帮助。
