在 Android 系统中使用原生广告模板

为有效利用本指南，您应该熟悉如何实现原生广告和原生横幅广告。

第 1 步：模板实现

• 原生广告
• 原生横幅广告

第 2 步：进一步自定义

• 原生广告
• 原生横幅广告

第 1 步：模板实现

在 Activity 类的顶部添加以下代码，以便导入 Facebook 广告 SDK：

import com.facebook.ads.*;

原生广告实现。

private NativeAd nativeAd;

public class NativeAdActivity extends Activity {
  @Override
  public void onCreate(Bundle savedInstanceState) {
    ...

    // Instantiate an NativeAd object. 
    // NOTE: the placement ID will eventually identify this as your App, you can ignore it for
    // now, while you are testing and replace it later when you have signed up.
    // While you are using this temporary code you will only get test ads and if you release
    // your code like this to the Google Play your users will not receive ads (you will get a no fill error).
    nativeAd = new NativeAd(this, "YOUR_PLACEMENT_ID");
    NativeAdListener nativeAdListener = new NativeAdListener() {
        ...
    };
    
    // Initiate a request to load an ad.
    nativeAd.loadAd(
            nativeAd.buildLoadAdConfig()
                    .withAdListener(nativeAdListener)
                    .withMediaCacheFlag(NativeAdBase.MediaCacheFlag.ALL)
                    .build());
  }
}        

如果您希望广告在加载后立即展示，可在 AdListener 的 onAdLoaded() 方法中显示自定义模板，并将其添加到您的容器中。

private NativeAd nativeAd;
...
  NativeAdListener nativeAdListener = new NativeAdListener() {
    ...
    @Override
    public void onAdLoaded(Ad ad) {
      // Render the Native Ad Template
      View adView = NativeAdView.render(MainActivity.this, nativeAd);
      LinearLayout nativeAdContainer = (LinearLayout) findViewById(R.id.native_ad_container);
      // Add the Native Ad View to your ad container. 
      // The recommended dimensions for the ad container are:
      // Width: 280dp - 500dp
      // Height: 250dp - 500dp
      // The template, however, will adapt to the supplied dimensions.
      nativeAdContainer.addView(adView, new LayoutParams(MATCH_PARENT, 800));  
    }
   ...
  }

运行此代码，随后您应看到以下内容：

原生横幅广告实现。

private NativeBannerAd mNativeBannerAd;
...

  @Override
  public void onCreate(Bundle savedInstanceState) {
    ...

    // Instantiate an NativeBannerAd object. 
    // NOTE: the placement ID will eventually identify this as your App, you can ignore it for
    // now, while you are testing and replace it later when you have signed up.
    // While you are using this temporary code you will only get test ads and if you release
    // your code like this to the Google Play your users will not receive ads (you will get a no fill error).
    mNativeBannerAd = new NativeBannerAd(this, "YOUR_PLACEMENT_ID");
    NativeAdListener nativeAdListener = new NativeAdListener() {
        ...
    };
    
    // Initiate a request to load an ad.
    mNativeBannerAd.loadAd(
            mNativeBannerAd.buildLoadAdConfig()
                    .withAdListener(nativeAdListener)
                    .build());
  }
}        

如果您希望广告在加载后立即展示，可在 AdListener 的 onAdLoaded() 方法中显示自定义模板，并将其添加到您的容器中。

@Override
public void onAdLoaded(Ad ad) {
  // Render the Native Banner Ad Template
  View adView = NativeBannerAdView.render(MainActivity.this, mNativeBannerAd, NativeBannerAdView.Type.HEIGHT_100);
  LinearLayout nativeBannerAdContainer = (LinearLayout) findViewById(R.id.native_banner_ad_container);
  // Add the Native Banner Ad View to your ad container
  nativeBannerAdContainer.addView(adView);  
}

运行此代码，随后您应看到以下内容：

自定义原生横幅广告格式包含三个模板：

第 2 步：进一步自定义

使用原生自定义模板，您可以自定义以下元素：

• 高度
• 宽度
• 背景颜色
• 标题颜色
• 标题字体
• 描述颜色
• 描述字体
• 按钮颜色
• 按钮标题颜色
• 按钮标题字体
• 按钮边框颜色

如需自定义特定元素，建议使用适合您应用布局和主题的设计。

您需要构建一个属性对象，并提供一个已加载的原生广告或原生横幅广告，才能显示上述元素：

原生广告示例。

构建一个 NativeAdViewAttributes 对象，并将其作为参数放入 NativeAdView.render() 中：

@Override
public void onAdLoaded(Ad ad) {
  // Set the Native Ad attributes
  NativeAdViewAttributes viewAttributes = new NativeAdViewAttributes()
    .setBackgroundColor(Color.BLACK)
    .setTitleTextColor(Color.WHITE)
    .setDescriptionTextColor(Color.LTGRAY)
    .setButtonColor(Color.WHITE)
    .setButtonTextColor(Color.BLACK);
  
  View adView = NativeAdView.render(MainActivity.this, nativeAd, viewAttributes);

  LinearLayout nativeAdContainer = (LinearLayout) findViewById(R.id.native_ad_container);
  // Add the Native Ad View to your ad container
  nativeAdContainer.addView(adView, new LayoutParams(MATCH_PARENT, 800));
}

上述代码呈现的广告如下：

原生横幅广告示例。

构建一个 NativeAdViewAttributes 对象，并将其作为参数放入 NativeBannerAdView.render() 中：

@Override
public void onAdLoaded(Ad ad) {
  // Set the NativeAd attributes
  NativeAdViewAttributes viewAttributes = new NativeAdViewAttributes()
    .setBackgroundColor(Color.BLACK)
    .setTitleTextColor(Color.WHITE)
    .setDescriptionTextColor(Color.LTGRAY)
    .setButtonColor(Color.WHITE)
    .setButtonTextColor(Color.BLACK);   
  
  View adView = NativeBannerAdView.render(MainActivity.this, nativeAd, NativeBannerAdView.Type.HEIGHT_100, viewAttributes);

  LinearLayout nativeBannerAdContainer = (LinearLayout) findViewById(R.id.native_banner_ad_container);
  // Add the Native Banner Ad View to your ad container
  nativeBannerAdContainer.addView(adView);  
}

上述代码呈现的广告如下：
