如何在Xamarin中的ListView.Header和ListView.ItemTemplate上创建多行？

我正在尝试在

ListView.Header

和

ListView.ItemTemplate

上创建多行，但没有找到任何示例

                    <Grid.RowDefinitions>
                        <RowDefinition></RowDefinition><!--row 1-->
                        <RowDefinition></RowDefinition><!--row 2-->                            
                    </Grid.RowDefinitions>

                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 1-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 2-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 3-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 4-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 5-->
                    </Grid.ColumnDefinitions>

                    <!--margin (left, top, right, bottom)-->
                    <!--row 1-->
                    <Label Grid.Row="0" Grid.Column="0" FontAttributes="Bold" Text="ROMANEIO"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="1" FontAttributes="Bold" Text="DATA" TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="2" FontAttributes="Bold" Text="L/KG"    TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="3" FontAttributes="Bold" Text="SACAS"    TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="4" FontAttributes="Bold" Text="%UMI"    TextColor="White" HorizontalOptions="Center"></Label>


                    <!--row 2 -->
                    <Label Grid.Row="1" Grid.Column="0" FontAttributes="Bold" Text="%IMP"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="1" Grid.Column="1" FontAttributes="Bold" Text="%AVA"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="1" Grid.Column="2" FontAttributes="Bold" Text="%ESV"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="1" Grid.Column="3" FontAttributes="Bold" Text="%OUT"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="1" Grid.Column="4" FontAttributes="Bold" Text="%QBR"   TextColor="White" HorizontalOptions="Center"></Label>                        
                </Grid>

            </ListView.Header>

我怎么能这样做

                    <Grid.RowDefinitions>
                        <RowDefinition></RowDefinition><!--row 1-->
                        <RowDefinition></RowDefinition><!--row 2-->                            
                    </Grid.RowDefinitions>

                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 1-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 2-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 3-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 4-->
                        <ColumnDefinition Width="*"></ColumnDefinition><!--col 5-->
                    </Grid.ColumnDefinitions>

                    <!--margin (left, top, right, bottom)-->
                    <!--row 1-->
                    <Label Grid.Row="0" Grid.Column="0" FontAttributes="Bold" Text="ROMANEIO"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="1" FontAttributes="Bold" Text="DATA" TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="2" FontAttributes="Bold" Text="L/KG"    TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="3" FontAttributes="Bold" Text="SACAS"    TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="0" Grid.Column="4" FontAttributes="Bold" Text="%UMI"    TextColor="White" HorizontalOptions="Center"></Label>


                    <!--row 2 -->
                    <Label Grid.Row="1" Grid.Column="0" FontAttributes="Bold" Text="%IMP"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="1" Grid.Column="1" FontAttributes="Bold" Text="%AVA"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="1" Grid.Column="2" FontAttributes="Bold" Text="%ESV"   TextColor="White" HorizontalOptions="Center"></Label>
                    <Label Grid.Row="1" Grid.Column="3" FontAttributes="Bold" Text="%OUT"   TextColor="White" HorizontalOptions="Center"></Label>

                </Grid>

            </ListView.Header>

需要

如果您想使用listview头的模板，您可以使用

listview.HeaderTemplate
