打赏后如何自动关闭打赏广告 [Android-Studio]

Question

所以我试图让它在奖励用户后自动关闭广告，这是我到目前为止所得到的。请记住，我是 android studio 和 java 的新手。如果它们间隔开，则它们采用不同的方法。private RewardedVideoAd mAd;AdView adView;void init_admob(){    adView = (AdView) findViewById(R.id.adView);    AdRequest adRequest = new AdRequest.Builder().setRequestAgent("android_studio:ad_template").build();    adView.loadAd(adRequest);    mAd = MobileAds.getRewardedVideoAdInstance(this);    mAd.setRewardedVideoAdListener(this);    loadRewardedVideoAd();}public void onRewarded(RewardItem reward) {    Toast.makeText(this, reward.getAmount()+ " " +getString(R.string.points_received), Toast.LENGTH_SHORT).show();    award(reward.getAmount(),getString(R.string.admob_credit));    exitAd();}public void exitAd() {    //dispatchKeyEvent(new KeyEvent (KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK)); Tried But didn't work (No Errors Just didn't work)    //dispatchKeyEvent(new KeyEvent (KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK)); Tried but didn't work (No Errors Just didn't work)    try {        LinearLayout linLay = (LinearLayout) findViewById(R.id.adView);        linLay.removeView(adView);    } catch (Exception e) {        e.printStackTrace();    }}linLay 错误java.lang.ClassCastException: com.google.android.gms.ads.AdView cannot be cast to android.widget.LinearLayout所以我真的不知道还有什么可尝试的，或者在广告获得任何帮助后如何关闭 AdView！

Answer 1

我不认为这是可能的。这在法律上也是不正确的。当您展示广告时，您应该等待用户点击或取消广告。如果您以编程方式关闭，则意味着您已有效地强迫用户取消广告。（可能对用户有好处，但要站在广告商的角度考虑）

Answer 2

您无法关闭应用内广告，但这是我所做的。

private fun showRewardedVideo() {

    if (mRewardedAd.isLoaded) {

      mRewardedAd.show(

              this,

              object : RewardedAdCallback() {

                  override fun onUserEarnedReward(

                          rewardItem: RewardItem

                  ) {

                      Toast.makeText(this@MainActivity, "onUserEarnedReward", Toast.LENGTH_LONG).show()

                      addCoins(rewardItem.amount)

                     // come back to ad activity

                      startActivity(Intent(this@MainActivity, MainActivity2::class.java))

                  }
