在 Flutter 中实现 Firebase 原生广告

Question

我想使用 firebase_admob 和 Native 广告通过我的 Flutter 应用获利。在 firebase_admob 的 pub.dev 页面中，他们只显示了 Java 的步骤，但我的 MainActivity 页面是在 Kotlin 中。我对科特林一无所知。如何实现从 MainActivity.java 到 MainActivity.kt 的相同内容？

Java代码：

package my.app.path;

import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.firebaseadmob.FirebaseAdMobPlugin;

public class MainActivity extends FlutterActivity {
  @Override
  public void configureFlutterEngine(FlutterEngine flutterEngine) {
    flutterEngine.getPlugins().add(new FirebaseAdMobPlugin());

    FirebaseAdMobPlugin.registerNativeAdFactory(flutterEngine, "adFactoryExample", NativeAdFactoryExample());
  }

  @Override
  public void cleanUpFlutterEngine(FlutterEngine flutterEngine) {
    FirebaseAdMobPlugin.unregisterNativeAdFactory(flutterEngine, "adFactoryExample");
  }
}

给你伙计

注意：java-kotlin 转换器转换得很好，但你必须在 中再添加一件事"customOptions", "?" 标志以防止在我已经添加的原生广告加载到屏幕上时出现恐慌攻击，因此您可以复制粘贴。

MainActivity.kt

import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.googlemobileads.GoogleMobileAdsPlugin
import io.flutter.plugins.googlemobileads.GoogleMobileAdsPlugin.NativeAdFactory


class MainActivity : FlutterActivity() {
    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)
        val factory: NativeAdFactory = NativeAdFactoryExample(layoutInflater)
        GoogleMobileAdsPlugin.registerNativeAdFactory(flutterEngine, "adFactoryExample", factory)
    }

    override fun cleanUpFlutterEngine(flutterEngine: FlutterEngine) {
        GoogleMobileAdsPlugin.unregisterNativeAdFactory(flutterEngine, "adFactoryExample")
    }
}

NativeAdFactoryExample.kt

import android.graphics.Color
import android.util.Log
import android.view.LayoutInflater
import android.view.View
import android.widget.TextView
import com.google.android.gms.ads.formats.UnifiedNativeAd
import com.google.android.gms.ads.formats.UnifiedNativeAdView
import io.flutter.plugins.googlemobileads.GoogleMobileAdsPlugin.NativeAdFactory


internal class NativeAdFactoryExample(private val layoutInflater: LayoutInflater) : NativeAdFactory {
    override fun createNativeAd(
        nativeAd: UnifiedNativeAd, customOptions: Map<String, Any>?): UnifiedNativeAdView {
        val adView = layoutInflater.inflate(R.layout.my_native_ad, null) as UnifiedNativeAdView
        val headlineView = adView.findViewById<TextView>(R.id.ad_headline)
        val bodyView = adView.findViewById<TextView>(R.id.ad_body)
        headlineView.text = nativeAd.headline
        bodyView.text = nativeAd.body
        adView.setBackgroundColor(Color.YELLOW)
        adView.setNativeAd(nativeAd)
        adView.bodyView = bodyView
        adView.headlineView = headlineView
        return adView
    }
}
