Apps Avoid the keyboard to popup

[Kumidan]

I have a textview where to put a date.
I've associated to this field a date picker, the problem is that at the first touch the keyboard pops up and I have to tap a second time the field to show the picker.

How can I avoid the keyboard to pop up?

Solved, I've put
android:focusable="false"
into the xml
