Link Phone Number in App to Dialer (Android)

How do you link a phone number to the the dialer on an Androi开发者_开发知识库d App?

I have tried the

android:phoneNumber="true"

in the xml for the textView, but that did not work.

I want it so that the person touches the number and their phone's dialer opens up and they can push call and call the company I am developing this app for

add android:autoLink="phone" in xml

You could also use the Linkify class:
