如何从静态片段显示Admob间隙广告？

<LinearLayout
    android:id="@+id/adLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">
</LinearLayout>

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

public class YourFragment extends Fragment {
    private AdView adView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.your_fragment_layout, container, false);

        adView = new AdView(getActivity());
        adView.setAdUnitId("YOUR_AD_UNIT_ID");
        adView.setAdSize(AdSize.BANNER);

        LinearLayout adLayout = view.findViewById(R.id.adLayout);
        adLayout.addView(adView);

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

        return view;
    }

    @Override
    public void onResume() {
        super.onResume();
        adView.resume();
    }

    @Override
    public void onPause() {
        super.onPause();
        adView.pause();
    }
}
