How do I create one Preference with an EditTextPreference and a Togglebutton?

Question

What I'm trying to implement is basically and exact replica of the image below (the preferences that I've squared). Pressing anything to the left of the preference should open up a dialog. Pressing the togglebutton will disable/enable whatever I'm setting in this preference.

I've been trying for hours now and I've come up empty-handed. How do I implement this in a PreferenceActivity?

EDIT: It seems people are misunderstanding my question. It is very important that I figure out how to solve my problem using a PreferenceActivity. NOT an Activity. I don't care whether I need to do it in XML or programatically. Just please refrain from providing me with answers that I cannot use within a or something similar.

EDIT 2 : Added a bounty - I really need an answer to this
