NumberPickerDialog not picking up on NumberPicker EditText changes.

Fixed an issue where when the user changes the NumberPicker value using the keyboard and the EditText, then they pressed the set value button, the NumberPickerDialog was still calling onNumberSet with the old value.  An explanation of the issue can be found [here](http://stackoverflow.com/questions/3691099/android-numberpicker-not-saving-edittext-changes).

When you have an activity with only the NumberPicker and maybe a button or a spinner, and you edit it and try to click elsewhere, its onFocusChangedListener is not handled properly. So you just need to force it to lost focus before using getValue(). Worked like a charm to me.
