Multiple Clickable links in TextView on Android

Question

I'm trying to add multiple links in a textview similar to what Google & Flipboard has done below with their Terms and conditions AND Privacy Policy shown in the screen shot below:

So far I've stumbled on using this approach

textView.setText(Html.fromHtml(myHtml); textView.setMovementMethod(LinkMovementMethod.getInstance());

where myHtml is a href.

But it doesn't give me control I need e.g to launch a fragment etc.

Any idea how they achieve this in the two examples below?

You can use Linkify (android.text.Spannable,java.util.regex.Pattern,java.lang.String)

String termsAndConditions = getResources().getString(R.string.terms_and_conditions);
String privacyPolicy = getResources().getString(R.string.privacy_policy);

legalDescription.setText(
    String.format(
        getResources().getString(R.string.message),
        termsAndConditions,
        privacyPolicy)
);
legalDescription.setMovementMethod(LinkMovementMethod.getInstance());

Pattern termsAndConditionsMatcher = Pattern.compile(termsAndConditions);
Linkify.addLinks(legalDescription, termsAndConditionsMatcher, "terms:");

Pattern privacyPolicyMatcher = Pattern.compile(privacyPolicy);
Linkify.addLinks(legalDescription, privacyPolicyMatcher, "privacy:");

and then you can use the scheme to start an activity for example by adding the scheme in the AndroidManifest:

<intent-filter>
    <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="terms" />
    <data android:scheme="privacy" />
</intent-filter>

If you want to do a custom action, you can set the intent-filter to your current activity, which will have a singleTop launchmode.

This will cause onNewIntent to be fired where can make your custom actions:

@Override
protected void onNewIntent(final Intent intent) {
 ...
  if (intent.getScheme().equals(..)) {
    ..
  }
}
