I am sure this will help!

Unfortunately, it's not a quick, simple control. Check out the framework source code for an example.

There's an open source project for that component:

You can check the implementation in the framework sdk. A full example should be in the contact part (if you click on the contact image).

It should be somewhere around here : https://android.googlesource.com/platform/packages/apps/Contacts/+/master/src/com/android/contacts
