How to load interstitial ads admob on adview?

Question

This is the code for when I use native express ads (working)

RelativeLayout mAdView = (RelativeLayout)findViewById(R.id.adView);
NativeExpressAdView adObj = new NativeExpressAdView(this);
adObj.setAdUnitId(getResources().getString(R.string.native_ad_unit_id));
adObj.setAdSize(new AdSize(800,800));
mAdView.addView(adObj);

AdRequest request = new AdRequest.Builder().build();
adObj.loadAd(request);

And this code is for when I use interstitial ads (working)

InterstitialAd adObj = new InterstitialAd(this);
adObj.setAdUnitId(getResources().getString(R.string.interstitial_ad_id));

AdRequest request = new AdRequest.Builder().build();
adObj.loadAd(request);
adObj.show();

Can I use Interstitial ads like native express, not pop up just on layout?

Answer 1

非页内广告的主要功能是在布局上展示广告，但如果您想要弹出广告，请使用其他广告

Answer 2

InterstitialAd interstitialAd;
public void show(Context context) {

    interstitialAd = new InterstitialAd(context);

    interstitialAd.setAdUnitId(context.getResources().getString(R.string.id_ad_interstitial));

    AdRequest adRequest = new AdRequest.Builder().build();

    interstitialAd.loadAd(adRequest);

    interstitialAd.setAdListener(new AdListener() {
        public void onAdLoaded() {
            // Call displayInterstitial() function
            displayInterstitial();
        }
    });
}

public void displayInterstitial() {
    // If Ads are loaded, show Interstitial else show nothing.
    if (interstitialAd.isLoaded()) {
        interstitialAd.show();
    }
}
