BetterLinkMovementMethod

When android:autoLink="all" or Linkify.addLinks(textView, Linkify.ALL) is used to add links to web URLs, phone-numbers, map addresses or email addresses in a TextView, Android uses a class known as LinkMovementMethod that handles highlighting links when they're focused and dispatching an Intent when they're clicked.

BetterLinkMovementMethod improves over LinkMovementMethod, by fixing its flaws:

No support for custom URL click listeners. For eg., phone numbers always show up in the dialer when clicked and there's no way to manually handle the click.
Incorrect calculation of touch areas for links, resulting in ghost touch areas (Example video)
Unreliable highlighting of links (Example video)

A detailed explanation of why (and when) you should use BetterLinkMovementMethod can be read on my blog: http://saket.me/better-url-handler-textview-android/

Download

Add this to your module's build.gradle:

repositories {
    jcenter()
}

dependencies {
    compile 'me.saket:better-link-movement-method:2'
}

Sample

You can find sample APKs on the releases page to see BetterLinkMovementMethod in action.

Usage

BetterLinkMovementMethod is designed to be a drop-in replacement for LinkMovementMethod.

TextView textView = (TextView) findViewById(R.id.text1);
textView.setMovementMethod(BetterLinkMovementMethod.newInstance());
Linkify.addLinks(textView, Linkify.PHONE_NUMBERS);

However, the easiest way to get started is by using one of its linkify() methods:

BetterLinkMovementMethod.linkify(int linkifyMask, TextView...);
BetterLinkMovementMethod.linkify(int linkifyMask, ViewGroup);
BetterLinkMovementMethod.linkify(int linkifyMask, Activity);

// Where linkifyMask can be one of Linkify.ALL, Linkify.PHONE_NUMBERS,
// Linkify.MAP_ADDRESSES, Linkify.WEB_URLS and Linkify.EMAIL_ADDRESSES.

Examples

BetterLinkMovementMethod method = BetterLinkMovementMethod.linkify(Linkify.ALL, textView);
method.setOnLinkClickListener((textView, url) -> {
  // Do something with the URL and return true to indicate that this URL was handled.
  // Otherwise, return false to let the framework handle the URL.
  return true;
});
method.setOnLinkLongClickListener((textView, url) -> {
  // Handle long-clicks.
  return true;
});

// Or the less verbose way
BetterLinkMovementMethod
    .linkify(Linkify.ALL, textView)
    .setOnLinkClickListener((textView, url) -> {
      // Handle clicks.
      return true;
    })
    .setOnLinkLongClickListener((textView, url) -> {
      // Handle long-clicks.
      return true;
    });

You can also choose to go the shorter route of registering BetterLinkMovementMethod on all TextViews in your Activity’s layout in one go:

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  BetterLinkMovementMethod.linkify(Linkify.ALL, this);
}

When using in a non-Activity context (e.g., Fragments), you can also pass a ViewGroup as the 2nd param:

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  View view = inflater.inflate(R.layout.your_fragment, container, false);

  BetterLinkMovementMethod.linkify(Linkify.ALL, ((ViewGroup) view));

  return view;
}
