Question

我正在制作一个GymExercises应用程序。我有两个问题：

我在每个练习中都包含广告，但现在用户界面太多了。如何将它们放在后台以便它们在后台运行？
当我使用智能横幅时，有时它不会显示广告。使用小横幅，它可以很好地工作。

BenchFragment.java：

package com.Hristijan.Aleksandar.GymAssistant.Exercises; 
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Handler;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.MediaController;
import android.widget.VideoView;
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView; 

public class BenchFragment extends Fragment {

    private VideoView player;
    private String videopath;
    private MediaController mediacon;
    public  View rootView;
    private AdView mAdView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {

        rootView = inflater.inflate(R.layout.fragment_bench, container, false);
        mAdView = rootView.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        MobileAds.initialize(getActivity().getApplicationContext(), "ca-app-pub-7751214307362146~7028081975");
        mAdView.loadAd(adRequest);
        mediacon = new MediaController(getActivity());
        player = (VideoView) rootView.findViewById(R.id.videoplayer);
        videopath = "android.resource://" + getActivity().getPackageName() + "/" + R.raw.bench;
        player.setVideoURI(Uri.parse(videopath));
        mediacon.setAnchorView(player);
        player.start();
        player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {
                mp.setLooping(true);
                mp.setVolume(0, 0);
            }
        });
        return rootView;
    }
}

fragment_bench.xml：
