1.) Automatically linkifies using android:autoLink="all"
// res/values/strings.xml
<string name="link_text_auto"><b>text1:</b> This is some text. In
this text are some things that are actionable. For instance,
you can click on //www.google.com and it will launch the
web browser. You can click on google.com too. And, if you
click on (415) 555-1212 it should dial the phone.
</string>
// main.xml
<!-- text1 automatically linkifies things like URLs and phone numbers. -->
<TextView xmlns:android="//schemas.android.com/apk/res/android"
android:id="@+id/text1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:autoLink="all"
android:text="@string/link_text_auto"
/>
2.) Link text by setMovementMethod
// MainActivity.java onCreate
/*Be warned that if you want a TextView with a key listener or movement method not to be focusable, or if you want a TextView without a key listener or movement method to be focusable, you must call setFocusable(boolean) again after calling this to get the focusability back the way you want it. */
TextView t2 = (TextView) findViewById(R.id.text2);
t2.setMovementMethod(LinkMovementMethod.getInstance());
// main.xml
<!-- text2 uses a string resource containing explicit <a> tags to
specify links. -->
<TextView xmlns:android="//schemas.android.com/apk/res/android"
android:id="@+id/text2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@string/link_text_manual"
/>
//strings.xml
<string name="link_text_manual"><b>text2:</b> This is some other
text, with a <a href="//www.google.com">link</a> specified
via an <a> tag. Use a "tel:" URL
to <a href="tel:4155551212">dial a phone number</a>.
</string>
3.) Link as html code using Html.fromHtml()
// MainActivity.java onCreate
TextView t3 = (TextView) findViewById(R.id.text3);
t3.setText(
Html.fromHtml(
"<b>text3:</b> Text with a " +
"<a href="//www.google.com">link</a> " +
"created in the Java source code using HTML."));
t3.setMovementMethod(LinkMovementMethod.getInstance());
4.) Link string by SpannableString
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());
