如何通过在Android中使用广告侦听器来设置来自另一个活动的按钮的可见性

Question

我正在开发一个Android应用程序，我正在尝试通过广告侦听器设置按钮的visiblity。有两个活动

1(MainActivity-其中包含2个按钮按钮1＆amp;Button 3，WebView和间质广告。另一个活动是我有一个隐形按钮的适当性。我想让广告听众从间隙广告中看到该按钮。

        MobileAds.initialize(this,"ca-app-pub-3940256099942544~3347511713");
        mAdview = (AdView)findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdview.loadAd(adRequest);

        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(interstitialAd.isLoaded())
                {
                    interstitialAd.show();
                }
                else
                {
                    Intent intent = new Intent(MainActivity.this,AdActivity.class);
                    startActivity(intent);
                }
            }
        });
        interstitialAd.setAdListener(new AdListener()
                                     {
                                         @Override
                                         public void onAdClicked() {
                                             Intent nextActivity = new Intent(MainActivity.this, AdActivity.class);
                                             Bundle bundle = new Bundle();
                                             bundle.putInt("VAL", 1);
                                             nextActivity.putExtras(bundle);
                                             startActivity(nextActivity);
                                         }
                                     }

        ); 
    }
}

 Bundle bun=getIntent().getExtras();
        int val=bun.getInt("VAL");

        if(val==1)
        {
            button2.setVisibility(View.VISIBLE);
        }

Bundle中的传递值：

Intent intent = new Intent(A.this, B.class);
Bundle extras = new Bundle();
extras.putString("VAL", 1 + "");
intent.putExtras(extras);
startActivity(intent);

从Bundle获取值：

Bundle extras = getIntent().getExtras();
String strVal = extras.getString("VAL");
int intVal = Integer.parseInt(strVal);
