如何在 android studio 中实现 Admob 插页式广告 - Kotlin

Question

我是一名初学者，我需要帮助在 android studio 中使用 Kotlin 实施 Admob 插页式广告。对不起我的问题，如果你能一步一步地向我展示，那么我可以学习这个过程并每隔一段时间自己做一次。提前致谢。

package com.example.myapplication

import android.content.ContentValues.TAG
import android.content.Intent
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import android.widget.TextView
import com.google.android.gms.ads.*
import com.google.android.gms.ads.interstitial.InterstitialAd
import com.google.android.gms.ads.interstitial.InterstitialAdLoadCallback

class MainActivity : AppCompatActivity() {

    private var mInterstitialAd: InterstitialAd? = null


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val one_Page: TextView = findViewById(R.id.one_Page)
        val three_Page: TextView = findViewById(R.id.three_Page)

   

        one_Page.setOnClickListener {
            val intent = Intent(this, PageActivity2::class.java)
            // start your next activity
            startActivity(intent)

        }
        three_Page.setOnClickListener {
            val intent = Intent(this, PageActivity2::class.java)
            // start your next activity
            startActivity(intent)
        }


    }

}

我认为您可能遗漏了几个步骤以使其正确，请按照以下步骤操作：

注意：我将使用示例 ID 加载演示广告，您需要确保它可以正常工作，然后考虑将示例 ID 替换为真实 ID

1：设置 Admob 依赖项：

implementation 'com.google.android.gms:play-services-ads:20.1.0'

2：在<application>标签内的AndroidManifest.xml中添加sn-p代码

<!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
<!-- Replace sample id if you have a real id from AdMob project - pattern ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy --> 
<meta-data
     android:name="com.google.android.gms.ads.APPLICATION_ID"
     android:value="ca-app-pub-3940256099942544~3347511713"/>

3：初始化 Admob 并加载广告：

import com.google.android.gms.ads.interstitial.InterstitialAd
import com.google.android.gms.ads.interstitial.InterstitialAdLoadCallback
class MainActivity : AppCompatActivity() {
  private var mInterstitialAd: InterstitialAd? = null
  private final var TAG = 'MainActivity'
    override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)

      // Initialize Admob
      MobileAds.initialize(this) {}
      var adRequest = AdRequest.Builder().build()
      // ca-app-pub-3940256099942544/1033173712 is a sample interstial id. 
      InterstitialAd.load(this,"ca-app-pub-3940256099942544/1033173712", adRequest, object : InterstitialAdLoadCallback() {
        override fun onAdFailedToLoad(adError: LoadAdError) {
          Log.d(TAG, adError?.message)
          mInterstitialAd = null
        }

        override fun onAdLoaded(interstitialAd: InterstitialAd) {
          Log.d(TAG, 'Ad was loaded.')
          mInterstitialAd = interstitialAd
        }
      })
    }
}

4：在InterstitialAd.load下面添加FullScreenContentCallback：

mInterstitialAd?.fullScreenContentCallback = object: FullScreenContentCallback() {
  override fun onAdDismissedFullScreenContent() {
    Log.d(TAG, 'Ad was dismissed.')
  }

  override fun onAdFailedToShowFullScreenContent(adError: AdError?) {
    Log.d(TAG, 'Ad failed to show.')
  }

  override fun onAdShowedFullScreenContent() {
    Log.d(TAG, 'Ad showed fullscreen content.')
    mInterstitialAd = null;
  }
}

6：将 showFullAd 添加到 MainActivity 并在要显示的 Activity 中调用 showFullAd

fun showFullAd(){
    if (mInterstitialAd != null) {
      mInterstitialAd?.show(this)
    } else {
      Log.d("TAG", "The interstitial ad wasn't ready yet.")
    }
}

https://developers.google.com/admob/android/interstitial#kotlin 解释了如何请求插页式广告。您上面的代码创建了一个mInterstitialAd 变量，但仍需要：

1. 加载广告
2. 在应用的自然停止点展示广告
