Question

我想在appbar中有一个注销图标。我确信它应该是常见的样式，但发现不幸的是它不是。

那么，我该怎么做呢？

Answer 1

我找到了this网站，在那里我找到了我想要注销按钮的图标，并复制了给我路径的xaml。接下来，我将此代码添加到common：

<Style x:Key="LogoutAppBarButtonStyle" TargetType="ButtonBase" BasedOn="{StaticResource AppBarButtonStyle}">
    <Setter Property="AutomationProperties.AutomationId" Value="LogoutAppBarButton" />
    <Setter Property="AutomationProperties.Name" Value="Logout" />
    <Setter Property="ContentTemplate">
        <Setter.Value>
            <DataTemplate>
                <Grid>
                    <Viewbox RenderTransformOrigin="0.47,0.47">
                        <Viewbox.RenderTransform>
                            <TransformGroup>
                                <CompositeTransform Rotation="0" ScaleX="0.551720260135184" ScaleY="0.551720260135184" />
                            </TransformGroup>
                        </Viewbox.RenderTransform>
                        <Path Stretch="Uniform"
                              Fill="{Binding Path=Foreground, RelativeSource={RelativeSource Mode=TemplatedParent}}"

                    </Viewbox>
                </Grid>
            </DataTemplate>
        </Setter.Value>
    </Setter>
</Style>

注意Path的Fill属性很重要，它不能是白色，因为当我们按下它并按住它时，默认的appbar图标变为白色，因此颜色应该变为黑色，并且因此，我们使用这个代码来获取父级的前景色 - AppBarButtonStyle，它已经按下appbar图标上的这个逻辑。这是代码：

Fill="{Binding Path=Foreground, RelativeSource={RelativeSource Mode=TemplatedParent}}"

还有一件事，我使用了一些渲染，因为图像有点弯曲，所以我通过渲染来修复它，也许不是最好的方法，但现在它完美无缺！

最后一步是将此添加到我想要使用登录appbar图标的所有页面：

<Button Style="{StaticResource LogoutAppBarButtonStyle}" Click="Logout_Click" />
