这是我的聊天窗口

我希望我看起来像标准的一个我不想扯掉facebook这只是一个学习练习，以更好地理解xaml。

我尝试在最后添加文本框，但显然由于某种原因它没有显示在图片中。我应该使用混合物吗？

修改

我的第二次尝试尝试

  <Grid Margin="0" Background="{StaticResource PhoneAccentBrush}" Grid.Row="1">
                        <Grid.RowDefinitions>
                            <RowDefinition Height="auto"/>
                            <RowDefinition Height="auto"/>
                        </Grid.RowDefinitions>

                        <TextBlock Foreground="White" Text="{Binding TextMessage}" x:Name="MainText2" TextWrapping="Wrap" Grid.Row="0" Width="300" FontSize="21.333" Padding="10,5,10,5">

                        </TextBlock>


                        <TextBox  x:Name="test" Text="test" TextWrapping="Wrap" Grid.Row="0" Width="300" FontSize="21.333" Padding="10,5,10,5"></TextBox>

如您所见，将其置于消息泡沫之上。

Answer 1

您需要将其放在列表之外。你的xaml应该是这样的：

<Grid>
  <ListView Margin="0 0 0 80"/> -- messages, with a bottom border so it doesn't overlap the textbox
  <TextBox VerticalAlignment="Bottom" Height="80"/> -- here you type your message
</Grid>

Answer 2

转到列表视图的属性，其中包含对齐的消息，请参见VerticalContentAlignment将其设置为bottom。

或添加以下代码：

<ListView x:Name="chatView" RenderTransformOrigin="0.5,0.5" Width="370" SelectionMode="None" ScrollViewer.VerticalScrollBarVisibility="Auto" HorizontalAlignment="Center" Margin="15,46,15,52" Loaded="chatView_Loaded" Height="542" VerticalContentAlignment="Bottom">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Grid Margin="0,10,0,10" HorizontalAlignment="Stretch" Width="370">
                <StackPanel  HorizontalAlignment="{Binding align}" Width="250" Background="#FF007ACC">
                    <TextBlock x:Name="msg" TextWrapping="Wrap" Text="{Binding msg}" FontSize="22.667">
                    </TextBlock>
                </StackPanel>
            </Grid>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>
