按下后退按钮显示非页内广告？

Question

这是我的清单文件:

<activity
        android:screenOrientation="portrait"
        android:name="com.google.android.gms.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:theme="@android:style/Theme.Translucent" />

这是我的活动:

 @Override
public void onBackPressed() {
    InterstitialAd interstitialAd= new InterstitialAd(this);
    interstitialAd.setAdUnitId(getString(R.string.interstitial_full_screen));
    AdRequest adRequest = new AdRequest.Builder().build();
    interstitialAd.loadAd(adRequest);

    interstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdLoaded() {

            if (interstitialAd.isLoaded()) {
                interstitialAd.show();
            }

        }

        @Override
        public void onAdClosed() {
            super.onAdClosed();
            finish();

        }
    });

}

在按下后退按钮的同时,我只获得了2-3次广告屏幕.所以,我可以在每次按下后按钮时解决它.

试试吧

InterstitialAd interstitialAd = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_blue);

       interstitialAd= new InterstitialAd(this);
        interstitialAd.setAdUnitId(getString(R.string.interstitial_full_screen));
        AdRequest adRequest = new AdRequest.Builder().build();
        interstitialAd.loadAd(adRequest);

    }


    @Override
    public void onBackPressed() {
    if (interstitialAd.isLoaded()) {
        interstitialAd.show();
        interstitialAd.setAdListener(new AdListener() {
            @Override
            public void onAdClosed() {
                super.onAdClosed();
                finish();
            }
        });
       }else{
           super.onBackPressed();
       }

    }
