在按钮上单击Admob插页式广告

我使用kotlin在android studio中制作了一个应用程序，当点击一个按钮的广告出现时，我尝试添加插页式广告，并在广告关闭后使用onAdClosed()方法显示第二个活动，问题在于应用程序有时候会在主要活动2中保持压制状态3.这就是我的代码的样子

 private lateinit var mInterstitialAd: InterstitialAd private lateinit var adRequest : AdRequest override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713") mInterstitialAd = InterstitialAd(this) mInterstitialAd.adUnitId = "ca-app-pub-3940256099942544/1033173712" requestNewInterstitial() button2.setOnClickListener{ val intent1 = Intent(this,Main2Activity::class.java) startActivity(intent1) if (mInterstitialAd.isLoaded) { mInterstitialAd.show() } else { } mInterstitialAd.adListener = object : AdListener() { override fun onAdClosed() { requestNewInterstitial() //go to second activity or do something } override fun onAdLoaded() { requestNewInterstitial() } override fun onAdFailedToLoad(i: Int) { requestNewInterstitial() } } } } private fun requestNewInterstitial() { adRequest = AdRequest.Builder().build() mInterstitialAd.loadAd(adRequest)} 

我想当用户点击按钮时，应该看到广告，当他关闭广告，他应该去第二次活动

尝试这个

 class MainActivity : AppCompatActivity() { lateinit var mInterstitialAd: InterstitialAd override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713") mInterstitialAd = InterstitialAd(this) mInterstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712") mInterstitialAd.loadAd(AdRequest.Builder().build()) mInterstitialAd.adListener = object : AdListener() { override fun onAdClicked() { super.onAdClicked() } override fun onAdClosed() { val intent = Intent(applicationContext, SecondActivity::class.java) startActivity(intent) } } btn.setOnClickListener { if (mInterstitialAd.isLoaded()) { mInterstitialAd.show() } else { Log.d("TAG", "The interstitial wasn't loaded yet.") } } } }
