android - 单击菜单按钮后如何在启动新 Activity 之前显示插页式广告？

Question

我使用选项菜单按钮转到第二个 Activity 。当用户在启动第二个 Activity 后单击该菜单按钮插页式广告时。但是我想在启动第二个 Activity 之前显示插页式广告，当用户点击插页式广告的关闭按钮时，第二个 Activity 应该启动。

我正在使用下面的代码来显示插页式广告。

case R.id.button_id:
   startActivity(new Intent(this, secondactivity.class ));               

                    interstitial = new InterstitialAd(getApplicationContext());
                    interstitial.setAdUnitId(getString(R.string.admob_interstetial_ad));
                    AdRequest adRequest9 = new AdRequest.Builder()
                            .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)


                            .build();
                    interstitial.loadAd(adRequest9);
                    interstitial.setAdListener(new AdListener() {
                        public void onAdLoaded() {
                            if (interstitial.isLoaded()) {
                                interstitial.show();
                            }
                        }
                    });


                    return true;

@user8240773 建议的答案是正确的，但有一种更有效的方法来处理您的问题。这是我的代码:

// Has the interstitial loaded successfully?
// If it has loaded, perform these actions
if(mInterstitialAd.isLoaded()) {
    // Step 1: Display the interstitial
    mInterstitialAd.show();
    // Step 2: Attach an AdListener
    mInterstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdClosed() {
            // Step 2.1: Load another ad
            AdRequest adRequest = new AdRequest.Builder()
                                    .addTestDevice(AdRequest.DEVICE_EMULATOR_ID)
                                    .build();
            mInterstitialAd.loadAd(adRequest);

            // Step 2.2: Start the new activity
            startActivity(new Intent(Activity1.this, Activity2.class));
        }
    });
}
// If it has not loaded due to any reason simply load the next activity
else {
    startActivity(new Intent(Activity1.this, Activity2.class));
}

这样一来，您也不必担心由于没有互联网连接或其他原因导致广告无法加载。此代码将按照您描述问题的方式处理所有内容。
