WPF微信聊天和通讯录按钮样式代码分享

一、先用Path画一下轮廓

<Path Stroke="Red" StrokeThickness="1" Margin="10" StrokeDashCap="Round">
  <Path.Data>
   <GeometryGroup>
    <PathGeometry Figures="M 4,40 A 16,13 0 1 1 10,45 L 3,48 Z" />
   </GeometryGroup>
  </Path.Data>
</Path>

<Path Stroke="Red" StrokeThickness="1" StrokeDashCap="Round" Margin="50">
  <Path.Data>
   <GeometryGroup>
    <PathGeometry Figures="M 12,30 A 6,10 0 1 1 18,30 L 30,40 L 30,45 L 0,45 L 0,40Z" />
    <PathGeometry Figures="M 25,25 L 35,25"/>
    <PathGeometry Figures="M 28,30 L 35,30"/>
    <PathGeometry Figures="M 32,35 L 35,35"/>
   </GeometryGroup>
  </Path.Data>
</Path>

路径图如下

二、将路径应用的样式里

 <!--聊天按钮的样式-->
 <Style x:Key="ChatStyle" TargetType="{x:Type RadioButton}">
  <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
  <Setter Property="Background" Value="Transparent"/>
  <Setter Property="BorderBrush" Value="Transparent"/>
  <Setter Property="BorderThickness" Value="0"/>
  <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
  <Setter Property="HorizontalContentAlignment" Value="Center"/>
  <Setter Property="VerticalContentAlignment" Value="Center"/>
  <Setter Property="Padding" Value="1"/>
  <Setter Property="Template">
   <Setter.Value>
    <ControlTemplate TargetType="{x:Type RadioButton}">
     <Border>
      <Path x:Name="btnPath" StrokeThickness="1" Stroke="Gray" Fill="#FF3E3E40">
       <Path.Data>
        <GeometryGroup>
         <PathGeometry Figures="M 4,40 A 16,13 0 1 1 10,45 L 3,48 Z" />
        </GeometryGroup>
       </Path.Data>
      </Path>
     </Border>
     <ControlTemplate.Triggers>
      <Trigger Property="IsChecked" Value="true">
       <Setter Property="Fill" Value="#FF14D212" TargetName="btnPath"/>
       <Setter Property="Stroke" Value="#FF14D212" TargetName="btnPath"/>
      </Trigger>
      <Trigger Property="IsMouseOver" Value="true">
       <Setter Property="Stroke" Value="White" TargetName="btnPath"/>
      </Trigger>
      <MultiTrigger>
       <MultiTrigger.Conditions>
        <Condition Property="IsChecked" Value="true"/>
        <Condition Property="IsMouseOver" Value="true"/>
       </MultiTrigger.Conditions>
       <MultiTrigger.Setters>
        <Setter Property="Stroke" Value="#FF14D212" TargetName="btnPath"/>
       </MultiTrigger.Setters>
      </MultiTrigger>
     </ControlTemplate.Triggers>
    </ControlTemplate>
   </Setter.Value>
  </Setter>
 </Style>

 <!--通讯录的样式-->
 <Style x:Key="FriendStyle" TargetType="{x:Type RadioButton}">
  <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>
  <Setter Property="Background" Value="Transparent"/>
  <Setter Property="BorderBrush" Value="Transparent"/>
  <Setter Property="BorderThickness" Value="0"/>
  <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
  <Setter Property="HorizontalContentAlignment" Value="Center"/>
  <Setter Property="VerticalContentAlignment" Value="Center"/>
  <Setter Property="Padding" Value="1"/>
  <Setter Property="Template">
   <Setter.Value>
    <ControlTemplate TargetType="{x:Type RadioButton}">
     <Border>
      <Path x:Name="btnPath" StrokeThickness="1" Stroke="Gray" Fill="#FF3E3E40">
       <Path.Data>
        <GeometryGroup>
         <PathGeometry Figures="M 12,30 A 6,10 0 1 1 18,30 L 30,40 L 30,45 L 0,45 L 0,40Z" />
         <PathGeometry Figures="M 25,25 L 35,25"/>
         <PathGeometry Figures="M 28,30 L 35,30"/>
         <PathGeometry Figures="M 32,35 L 35,35"/>
        </GeometryGroup>
       </Path.Data>
      </Path>
     </Border>
     <ControlTemplate.Triggers>
      <Trigger Property="IsChecked" Value="true">
       <Setter Property="Fill" Value="#FF14D212" TargetName="btnPath"/>
       <Setter Property="Stroke" Value="#FF14D212" TargetName="btnPath"/>
      </Trigger>
      <Trigger Property="IsMouseOver" Value="true">
       <Setter Property="Stroke" Value="White" TargetName="btnPath"/>
      </Trigger>
      <MultiTrigger>
       <MultiTrigger.Conditions>
        <Condition Property="IsChecked" Value="true"/>
        <Condition Property="IsMouseOver" Value="true"/>
       </MultiTrigger.Conditions>
       <MultiTrigger.Setters>
        <Setter Property="Stroke" Value="#FF14D212" TargetName="btnPath"/>
       </MultiTrigger.Setters>
      </MultiTrigger>
     </ControlTemplate.Triggers>
    </ControlTemplate>
   </Setter.Value>
  </Setter>
 </Style>

看下效果图

注意要点有几个：

1、Path原来必须要有填充，也就是说Fill必须要有值，否则会认为是透明，点击不到。

2、一定要设置MultiTrigger，否则当button被选中的时候，鼠标划过，依然会变白色。
