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 http://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="http://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="http://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="http://www.google.com">link</a> specified
      via an &lt;a&gt; 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=\"http://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());
