调整 Microsoft Ads 的大小

Question

您好，我在我的 UWP 应用程序中使用 Microsofts Ads，我希望广告在应用程序结束后调整大小，但无法正常工作。我了解广告控件必须采用有效尺寸（如 here 所述），因此我编写了这段代码来调整广告尺寸：

private void panel_SizeChanged(object sender, SizeChangedEventArgs e)
{
    if (e.NewSize.Width >= 728)
    {
        ad.Width = 728;
        ad.Height = 90;
    }
    else if (e.NewSize.Width >= 640)
    {
        ad.Width = 640;
        ad.Height = 100;
    }
    else if (e.NewSize.Width >= 480)
    {
        ad.Width = 480;
        ad.Height = 80;
    }
    else if (e.NewSize.Width >= 320)
    {
        ad.Width = 320;
        ad.Height = 50;
    }
    else if (e.NewSize.Width >= 300)
    {
        ad.Width = 300;
        ad.Height = 50;
    }
}

这使控件相应地调整大小，但控件内的广告看起来很糟糕。我添加了 ad.Refresh();最后，但这并没有改变任何事情。

有人知道该怎么办吗？

我遇到了你同样的问题。不幸的是，广告每 30 秒加载一次，您不能每 30 秒刷新一次。这是因为调用 Refresh() 方法失败的原因。我使用了一种解决方法，希望它能对您有所帮助。我有 "covered" 具有与广告相同大小（和位置）的 StackPanel 的广告。当我不得不改变广告的大小时，我已经展示了这个面板。在广告刷新时（可以通过回调AdRefreshed拦截），我隐藏了封面。

<StackPanel x:Name="AdsCover" Width="300" Height="50" Visibility="Visible"
                   Grid.Column="0" Grid.ColumnSpan="3" HorizontalAlignment="Left" VerticalAlignment="Bottom" Canvas.ZIndex="12" Background="WhiteSmoke">
            <Border x:Name="AdsBorder" BorderBrush="{x:Null}" Height="50">
                <TextBlock x:Name="AdsLoading" Text="Ads Loading..." HorizontalAlignment="Center" FontStyle="Italic" FontFamily="Calibri" FontSize="24"
                       TextAlignment="Center" VerticalAlignment="Center"/>
            </Border>
        </StackPanel>
        <UI:AdControl x:Name="adsMS" 
                ApplicationId="3f83fe91-d6be-434d-a0ae-7351c5a997f1"
                AdUnitId="10865270"
                HorizontalAlignment="Left"
                Height="50"
                VerticalAlignment="Bottom"
                Width="300"
                Grid.Column="0" Grid.ColumnSpan="3"
                Canvas.ZIndex="10"
                ErrorOccurred="OnAdErrorOccurred"
                AdRefreshed="OnAdRefreshed"/>

在后面的代码中，您必须更改广告尺寸，您可以这样做：

    ...
    // Change the size of the Ad. adsW and adsH are the new size
    adsMS->SetValue(WidthProperty, 1.0*adsW);
    adsMS->SetValue(HeightProperty, 1.0*adsH);
    // Cover panel with the same size
    AdsCover->SetValue(WidthProperty, 1.0*adsW);
    AdsCover->SetValue(HeightProperty, 1.0*adsH);
    AdsBorder->SetValue(HeightProperty, 1.0*adsH);

    // If the size are changed, I hide the Ad with the panel.
    // In this way, I can avoid to see the deformed Ad.
    // m_previousAdsWidth and m_previousAdsHeight are the previous size
    // of the Ad.
    if ((m_previousAdsWidth != adsW || m_previousAdsHeight != adsH)
        && m_previousAdsWidth > 0 && m_previousAdsHeight > 0)
    {
        AdsCover->SetValue(VisibilityProperty, Windows::UI::Xaml::Visibility::Visible);
    }
    m_previousAdsWidth = adsW;
    m_previousAdsHeight = adsH;
    ...

在回调 OnAdRefreshed() 中可以隐藏面板

// Called when the Ad is refreshed.
void DirectXPage::OnAdRefreshed(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
    // If the Ad is hidden by the cover panel, I will make it visible again.
    if (AdsCover->Visibility == Windows::UI::Xaml::Visibility::Visible)
        AdsCover->SetValue(VisibilityProperty, Windows::UI::Xaml::Visibility::Collapsed);
}
