在 Android 中实现横幅广告
Note: You must initialize Unity Ads before displaying a banner ad.
横幅广告需要特定类型的专用横幅 广告单元.
您可以像放置其他视图一样将横幅视图对象放入您的视图层次结构中。这允许您自定义每个横幅实例的位置，或显示多个横幅。
Note: app-ads.txt is an IAB initiative to combat fraud and create transparency in the advertising ecosystem. Ensure that you implement app-ads.txt as described. Otherwise, banner demand might be significantly decreased.
脚本实现
以下脚本示例是在屏幕上显示两个横幅广告以及用于测试它们的按钮的示例实现。
此示例对多个横幅视图对象使用单个侦听器。您也可以为每个横幅视图对象使用不同的侦听器。
Note: Unity Ads requires access to the currently running Activity, so the following example uses getApplicationContext(). Because this might not be suitable for all implementations, some customization might be required (depending on the integration).
实现 MREC 横幅格式
要在您的应用中显示中等矩形 (MREC) 尺寸的广告格式，请确保使用正确的尺寸，例如 300x250、300x300 或 450x450。在 300x250 MREC 横幅广告的情况下，请在以下示例代码中替换此部分
new UnityBannerSize(320, 50)使用此调整后的尺寸
new UnityBannerSize(300, 250)示例代码
