如何制作AdMob插页式广告，以便他们必须按广告才能继续

Question

我将在本月晚些时候在我的应用程序中运行一个comp，我想使用广告。我想要做的是当会员点击按钮显示广告时，如果他们点击广告打开Goog​​le Play，则会显示促销代码。我正在使用Ad Mob提供的股票代码来填充插页式广告。只是想知道如何编辑以便在点击广告后显示促销代码。

public class comp extends AppCompatActivity  {
  private InterstitialAd mInterstitialAd;
  private TextView  Pcode;


  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_comp);
    Pcode = (TextView) findViewById(R.id.PromoCode);

    mInterstitialAd = new InterstitialAd(this);
    mInterstitialAd.setAdUnitId(getString(R.string.fullscreen_ad_unit_id));
    Button bce = (Button) findViewById(R.id.bcompenter);
    bce.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showInterstitial();

            mInterstitialAd.setAdListener(new AdListener() {
                @Override
                public void onAdClosed() {
                    StartTask();
                }
            });
        }
    });
  }

  private void showInterstitial() {
    // Show the ad if it's ready. Otherwise toast and restart the game.
    if (mInterstitialAd != null && mInterstitialAd.isLoaded()) {
        mInterstitialAd.show();
    } else {
        Toast.makeText(this, "Thanks for installing using H20 Droid Apps", Toast.LENGTH_SHORT).show();
        StartTask();
    }
  }

  private void StartTask() {
    // Request a new ad if one isn't already loaded, hide the button, and kick off the timer.
    if (!mInterstitialAd.isLoading() && !mInterstitialAd.isLoaded()) {
        AdRequest adRequest = new AdRequest.Builder().build();
        mInterstitialAd.loadAd(adRequest);
        Pcode.setVisibility(View.VISIBLE);
    }
  }
}
