[Android] `CalendarDatePicker` within `MenuFlyoutItem` doesn't work

[pkar70]

Current behavior

CalendarDatePicker is not displayed.

Expected behavior

CalendarDatePicker should appear.

How to reproduce it (as minimally and precisely as possible)

Within XAML:

    <not_win:Grid Grid.Row="2" Name="uiAndroBottom" Margin="0,10,0,0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="120" />
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>
        <TextBlock Text=" " Name="tbDzien" Margin="10,0,0,0" VerticalAlignment="Center" />
        <StackPanel Orientation="Horizontal" Grid.Column="1">

            <AppBarSeparator Name="uiBarSeparat1"/>
            <AppBarButton x:Uid="resDay" Label="Kalendarz" Icon="Calendar" Name="uiKalend">
                <AppBarButton.Flyout>
                    <Flyout >
                        <CalendarDatePicker Name="uiDay" DateChanged="uiDay_Changed"/>
                    </Flyout>
                </AppBarButton.Flyout>
            </AppBarButton>
            <AppBarSeparator Name="uiBarSeparat2"/>
            <AppBarButton Label="..." x:Name="uiAndroSec">
                <AppBarButton.Flyout>
                    <MenuFlyout>
                        <MenuFlyoutItem x:Uid="resDayM" Text="Kalendarz" Name="uiKalendSec">
                            <Flyout >
                                <CalendarDatePicker Name="uiDaySec" DateChanged="uiDay_Changed"/>
                            </Flyout>
                        </MenuFlyoutItem>
                    </MenuFlyout>
                </AppBarButton.Flyout>
                </AppBarButton>
        </StackPanel>
    </not_win:Grid>

uiDay is correctly presented, but when I click on uiDaySec, nothing happens.

Thanks. Can you provide the device logs or any exception that may be raised when opening the popup?

[pkar70]

Nope. Because my tablet is physically broken, and emulator from Visual Studio doesn't work. I run this app within BlueStacks emulator, and I don't know how to connect VStudio debugger to app within it. But current version of app is here: https://github.com/pkar70/Anniversaries

Thanks. Logs are important to troubleshoot the issue, otherwise, try making a small repro sample to show the issue and attach it here.

Repro is given - no code is required, only XAML. Remove DateChanged attribute, and compile with empty xaml.cs file,

FYI, CalendarDatePicker is not currently supported on mobile, you need to use the DatePicker that maps to the native picker on mobile by default. We're planning to support it properly in the future but hasnt been prioritized.

But DatePicker looks differently than CalendarDatePicker... Some time ago, there was no CalendarDatePicker in Uno; I created PR with this, but this PR was never merged.

Indeed the PR was not merged because it was implementing the native view for CalendarDatePicker, something we did not want to implement because of the porting of the original source.
