# 扩展 #### 混合使用 实际项目中我们可能遇到这样的情况： 百度百青藤的开屏广告ecpm很低，但是它的原生自渲染ecpm相对较高，那我们是不是可以使用原生自渲染伪装成开屏来代替百度百青藤自己的开屏广告呢？这样收益岂不是更高！ 所以 TogetherAd 提供了混合使用的方案： 调用开屏广告时，如果随机到csj和gdt就调用其开屏进行展示，如果随机到baidu就使用原生自渲染伪装成开屏再进行展示。 详情可查看 Demo 中例子 [开屏和原生自渲染的混合](../demo/src/main/java/com/ifmvo/togetherad/demo/hybrid/SplashHybridActivity.kt)、[全屏视频和原生自渲染的混合](../demo/src/main/java/com/ifmvo/togetherad/demo/hybrid/VerticalPreMovieHybridActivity.kt) 这里只举了开屏和全屏视频的例子，更多使用场景同理，可自行发挥。原生自渲染可以和任何类型的广告混合使用。 #### 扩展现有的 Provider [CsjProvider.kt](../csj/src/main/java/com/ifmvo/togetherad/csj/CsjProvider.kt)、[GdtProvider.kt](../gdt/src/main/java/com/ifmvo/togetherad/gdt/GdtProvider.kt)、[BaiduProvider.kt](../baidu/src/main/java/com/ifmvo/togetherad/baidu/BaiduProvider.kt) 这三个文件分别是穿山甲、广点通、百青藤真正请求广告的代码，如果现有的Provider不符合你的需求，你可以通过``继承``的方式，按照自己的需求，对其他相应的方法进行``重写``。 以 Csj 的 Banner 广告为例，目前穿山甲只允许创建模板类型的 Banner 广告，CsjProvider.kt 中使用的就是通过 loadBannerExpressAd 方法请求模板类型Banner。如果你想用原生类型Banner，可以通过以下方式进行自定义： ```kotlin class CustomCsjProvider : CsjProvider() { private val tag = "CustomCsjProvider" object Banner { var supportDeepLink: Boolean = true //图片的宽高 internal var imageAcceptedSizeWidth = 600 internal var imageAcceptedSizeHeight = 257 fun setImageAcceptedSize(width: Int, height: Int) { imageAcceptedSizeWidth = width imageAcceptedSizeHeight = height } //Banner 刷新间隔时间 var slideIntervalTime = 30 * 1000 } override fun showBannerAd(activity: Activity, adProviderType: String, alias: String, container: ViewGroup, listener: BannerListener) { callbackBannerStartRequest(adProviderType, alias, listener) destroyBannerAd() val adSlot = AdSlot.Builder() .setCodeId(TogetherAdCsj.idMapCsj[alias]) //广告位id .setSupportDeepLink(Banner.supportDeepLink) .setImageAcceptedSize(Banner.imageAcceptedSizeWidth, Banner.imageAcceptedSizeHeight) .build() TogetherAdCsj.mTTAdManager.createAdNative(activity).loadBannerAd(adSlot, object : TTAdNative.BannerAdListener { override fun onBannerAdLoad(bannerAd: TTBannerAd?) { if (bannerAd == null) { callbackBannerFailed(adProviderType, alias, listener, "请求成功，但是返回的 bannerAd 为空") return } val bannerView = bannerAd.bannerView if (bannerView == null) { callbackBannerFailed(adProviderType, alias, listener, "请求成功，但是返回的 bannerView 为空") return } callbackBannerLoaded(adProviderType, alias, listener) bannerAd.setSlideIntervalTime(Banner.slideIntervalTime) container.removeAllViews() container.addView(bannerView) bannerAd.setBannerInteractionListener(object : TTBannerAd.AdInteractionListener { override fun onAdClicked(view: View?, type: Int) { callbackBannerClicked(adProviderType, listener) } override fun onAdShow(view: View?, type: Int) { callbackBannerExpose(adProviderType, listener) } }) bannerAd.setShowDislikeIcon(object : TTAdDislike.DislikeInteractionCallback { override fun onSelected(position: Int, value: String?) { container.removeAllViews() callbackBannerClosed(adProviderType, listener) } override fun onCancel() {} override fun onRefuse() {} }) } override fun onError(errorCode: Int, errorMsg: String?) { "onError".loge(tag) callbackBannerFailed(adProviderType, alias, listener, "错误码：$errorCode, 错误信息：$errorMsg") } }) } } ``` 然后 Application 中初始化时的代码修改： ```kotlin TogetherAdCsj.init(context = this, adProviderType = AdProviderType.CSJ.type, csjAdAppId = "5001121", appName = this.getString(R.string.app_name), providerClassPath = CustomCsjProvider::class.java.name) ``` #### 新增自定义 Provider 同样的原理，如果穿山甲、广点通、百青藤这三个平台已经满足不了你，你还想再加一个其他的广告平台，那你就可以这样，自定义一个Provider： ```Kotlin /** * 自定义小米广告提供商 * * 根据其他 Provider 可自行实现广告请求逻辑 * * Created by Matthew Chen on 2020/10/23. */ class XiaomiProvider: BaseAdProvider() { override fun showSplashAd(activity: Activity, adProviderType: String, alias: String, container: ViewGroup, listener: SplashListener) {} override fun showBannerAd(activity: Activity, adProviderType: String, alias: String, container: ViewGroup, listener: BannerListener) {} override fun destroyBannerAd() {} override fun requestInterAd(activity: Activity, adProviderType: String, alias: String, listener: InterListener) {} override fun showInterAd(activity: Activity) {} override fun destroyInterAd() {} override fun getNativeAdList(activity: Activity, adProviderType: String, alias: String, maxCount: Int, listener: NativeListener) {} override fun nativeAdIsBelongTheProvider(adObject: Any): Boolean { return false } override fun resumeNativeAd(adObject: Any) {} override fun pauseNativeAd(adObject: Any) {} override fun destroyNativeAd(adObject: Any) {} override fun requestRewardAd(activity: Activity, adProviderType: String, alias: String, listener: RewardListener) {} override fun showRewardAd(activity: Activity) {} } ``` 再创建一个文件模仿 TogetherAdGdt 自定义小米的初始化 ``` /** * 自定义小米初始化 * * Created by Matthew Chen on 2020/10/23. */ object TogetherAdXiaomi { var idMapXiaomi = mapOf() fun init(@NotNull context: Context, @NotNull adProviderType: String, @NotNull xiaomiAdAppId: String) { init(context, adProviderType, xiaomiAdAppId, null, null) } fun init(@NotNull context: Context, @NotNull adProviderType: String, @NotNull xiaomiAdAppId: String, providerClassPath: String? = null) { init(context, adProviderType, xiaomiAdAppId, null, providerClassPath) } fun init(@NotNull context: Context, @NotNull adProviderType: String, @NotNull xiaomiAdAppId: String, xiaomiIdMap: Map? = null) { init(context, adProviderType, xiaomiAdAppId, xiaomiIdMap, null) } fun init(@NotNull context: Context, @NotNull adProviderType: String, @NotNull xiaomiAdAppId: String, xiaomiIdMap: Map? = null, providerClassPath: String? = null) { TogetherAd.addProvider(AdProviderEntity(adProviderType, if (providerClassPath?.isEmpty() != false) XiaomiProvider::class.java.name else providerClassPath)) xiaomiIdMap?.let { idMapXiaomi = it } //小米SDK初始化 } } ``` 枚举里面添加``XIAOMI`` ```kotlin /* * 广告提供商枚举 * * Created by Matthew_Chen on 2018/8/23. */ enum class AdProviderType(val type: String) { //百度 Mob （ 百青藤 ） BAIDU("baidu"), //腾讯的广点通（ 优量汇 ） GDT("gdt"), //穿山甲 CSJ("csj"), //小米 XIAOMI("xiaomi") } ``` 最后不要忘记再Application中初始化： ```kotlin TogetherAdXiaomi.init(context = this, adProviderType = AdProviderType.XIAOMI.type, xiaomiAdAppId = "xxxxxxxx") ``` 以上只是举例子，更多扩展同理。
