[Bug] DatePicker / TimePicker Unfocused Event Fired When Focused

[lcm98]

Description

Android 9.0 (Pie) - API 28 only.

When the dialog for either the DatePicker or TimePicker is opened, the unfocused event from that picker is fired.

In this particular case, I am using the unfocused event of the DatePicker to focus on the TimePicker. The result is actually that as soon as the DatePicker calendar opens, the unfocused event instantly fires which then opens the TimePicker Clock overlayed on-top of the calendar.

This seems related to #5159 , except instead of the issue being that the dialog won't open at all, it opens and immediately fires the Unfocused event.

Steps to Reproduce

1. Have handler attached to Unfocused Event of DatePicker or TimePicker
2. Focus DatePicker or TimePicker via Code

Expected Behavior

Unfocused event is fired when dialog is closed.

Actual Behavior

Unfocused event fires as soon as dialog opens

With further testing, this issue seems to be isolated to when the DatePicker is initially focused via code (datePicker.Focus()) as opposed to clicking the visual element
