如何在windows phone app8.1中将普通按钮菜单项设置为AppBarButton？

下面是我的示例按钮代码

 <Button  VerticalAlignment="Bottom" HorizontalAlignment="Right"  Height="97" BorderThickness="0" Margin="331,0,-40,-62" >
                            <StackPanel>
                                <Image Source="Images/ic_navigation_drawer.png" Stretch="Fill" Width="59" Height="39"  />
                            </StackPanel>
                            <Button.Flyout>
                                <MenuFlyout>
                                    <MenuFlyoutItem x:Name="reloadcash" Text="Reloadcash" Click="reloadcash_Click" />
                                    <MenuFlyoutItem x:Name="prevoiusorders" Text="Previous orders" Click="prevoiusorders_Click"/>
                                    <MenuFlyoutItem x:Name="profile" Text="profile" Click="profile_Click"/>
                                    <MenuFlyoutItem x:Name="changepassword" Text="changepassword" Click="changepassword_Click"/>
                                    <MenuFlyoutItem x:Name="Contacts" Text="Contacts" Click="Contacts_Click"/>
                                    <MenuFlyoutItem x:Name="busorderhistory" Text="Busorderhistory" Click="busorderhistory_Click"></MenuFlyoutItem>

                                </MenuFlyout>
                            </Button.Flyout>
                        </Button>

现在我想将上面的菜单设置为将项目输出到AppBarButton中

<AppBarButton Icon="OpenPane" Label="menu">
            <AppBarButton.Flyout>
                <MenuFlyout>
                    <MenuFlyoutItem x:Name="reloadcash" Text="Reloadcash" Click="reloadcash_Click" />
                    <MenuFlyoutItem x:Name="prevoiusorders" Text="Previous orders" Click="prevoiusorders_Click"/>
                    <MenuFlyoutItem x:Name="profile" Text="profile" Click="profile_Click"/>
                    <MenuFlyoutItem x:Name="changepassword" Text="changepassword" Click="changepassword_Click"/>
                    <MenuFlyoutItem x:Name="Contacts" Text="Contacts" Click="Contacts_Click"/>
                    <MenuFlyoutItem x:Name="busorderhistory" Text="Busorderhistory" Click="busorderhistory_Click"/>
                </MenuFlyout>
            </AppBarButton.Flyout>
        </AppBarButton>

每当我单击AppBarbutton时，所有菜单项都会显示出来。 如何显示AppBarbutton中的所有菜单项。

                </MenuFlyout>
            </AppBarButton.Flyout>
        </AppBarButton>

这个很好用
