Android: manual change date DatePicker

I'm having trouble with the date picker. Just when the user changes the year, he/she presses a button that t开发者_Python百科akes you to the next screen. The problem here is that the year isn't set, it is set by default, and that's not correct. Can someone help me?

i solved it by forcing focus to another object, like a TextView, then processing the info and moving to the next screen. thanks for your cooperation anyway.
