Failed to add com.facebook.share.widget.Sharebutton to Layout XML

Question

I am trying to use the Facebook SDK in Android for Share Content Referral from my application.

I use the following code from here Facebook Docs :

ShareLinkContent content = new ShareLinkContent.Builder()
    .setContentUrl(Uri.parse("http://www.focusoutdistractions.com/"))
    .build();

    ShareButton shareButton = (ShareButton) rootView.findViewById(R.id.ibtn_twshare);
    shareButton.setShareContent(content);

Question . In the XML file, I need to add com.facebook.share.widget.Sharebutton to the XML, but it is not recognized.

Is com.facebook.share.widget.Sharebutton the correct XML element to add for this Sharebutton?
