如何在 UWP 中创建对话气泡? [英] How to create a speech bubble in UWP?

问题描述

我正在创建一个聊天应用程序，并希望创建包含每条消息的典型对话气泡.我在 Blend 中(在 XAML 中)创建了一个 Path 对象，如下所示:

I'm creating a chat application and would like to create the typical speech bubble that contains each message. I created a Path object in Blend (in XAML) like this:

问题是路径被设计为具有指定的宽度和高度，我希望它环绕文本而不拉伸，所以它不会看起来像边框一样变形

The problem is that the path is has designed to have a specified width and height and I would like it to wrap around the text without stretching, so it won't look deformed, like a border does.

我怎样才能让它表现得像我想要的那样?

How can I make it behave like I want?

推荐答案

您可以将 Polygon 与 StackPanel 结合使用:

You may use Polygon in combination with StackPanel:

<StackPanel Orientation="Horizontal"
            HorizontalAlignment="Left"
            Padding="6"
            >
    <Polygon Points="0,0 15,0 15,15"
             Fill="LightGray"
             Margin="0,10,0,0"
             />

    <Border Background="LightGray"
            CornerRadius="3"
            Padding="6"
            VerticalAlignment="Top"
            >
        <TextBlock Text="Text"
                   TextWrapping="WrapWholeWords"
                   Width="100"
                   Height="50"
                   />
    </Border>
</StackPanel>

看起来像这样:

带边框的版本:

<Grid HorizontalAlignment="Left"
      Padding="6"
      >
    <Polygon Points="0,0 15,0 15,15"
             Fill="LightGray"
             Stroke="Black"
             Margin="0,10,0,0"
             />

    <Border Background="LightGray"
            BorderBrush="Black"
            BorderThickness="0.5"
            CornerRadius="3"
            Padding="6"
            Margin="14,0,0,0"
            VerticalAlignment="Top"
            >
        <TextBlock Text="Text"
                   TextWrapping="WrapWholeWords"
                   Width="100"
                   Height="50"
                   />
    </Border>

    <Polygon Points="0,0 15,0 15,15"
             Fill="LightGray"
             Margin="0,10,0,0"
             />
</Grid>

这可能不是最简单和最好的方法，也许 Path 会更好地做到这一点，但它有效:

This is probably not the easiest and the best way how to do this, maybe Path will be better to do this, but it works:
