我的 AdMob 广告未在 android studio 中展示

Question

我的 AdMob 横幅未显示在我的 Android 应用程序中。在看到关于同一问题的旧问题后，没有任何帮助，因为它们指的是以前版本的 android studio。现在有些东西已经被弃用了。

我的NewRecord.java 文件包含以下代码：

package com.example.anxietycalendar;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

import com.akaita.android.circularseekbar.CircularSeekBar;
import com.google.android.gms.ads.AdListener;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.InterstitialAd;
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.initialization.InitializationStatus;
import com.google.android.gms.ads.initialization.OnInitializationCompleteListener;

import java.text.DateFormat;
import java.text.DecimalFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;

public class NewRecord extends AppCompatActivity {
    DatabaseHelper myDB;
    private Button Submit;
    public float pr;
    private AdView mAdView;

    private InterstitialAd mInterstitialAd;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_new_record);

        MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });
        mAdView = findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mAdView.loadAd(adRequest);
        mAdView.setAdListener(new AdListener() {
                                  @Override
                                  public void onAdFailedToLoad(int errorCode) {
                                      String onAdFailedToLoad = null;
                                      Log.d(onAdFailedToLoad, "This is why: " + errorCode);
                                  }
        });

        myDB=new DatabaseHelper(this);

        Submit= (Button) findViewById(R.id.submit);
        CircularSeekBar seekBar = (CircularSeekBar) findViewById(R.id.seekbar);
        seekBar.setProgressTextFormat(new DecimalFormat("###,###,###,##0.00"));
        seekBar.setProgress(0);
        seekBar.setRingColor(Color.GREEN);

        seekBar.setOnCircularSeekBarChangeListener(new CircularSeekBar.OnCircularSeekBarChangeListener() {
            @Override
            public void onProgressChanged(CircularSeekBar seekBar, float progress, boolean fromUser) {
                if (progress < 5) {
                    seekBar.setRingColor(Color.GREEN);
                    pr = progress;
                } else if (progress < 8) {
                    seekBar.setRingColor(Color.YELLOW);
                    pr = progress;
                } else {
                    seekBar.setRingColor(Color.RED);
                    pr = progress;
                }
            }

            @Override
            public void onStartTrackingTouch(CircularSeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(CircularSeekBar seekBar) {

            }
        });

        Submit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                myDB.insertData(Math.round(pr));
            }
        });


    }


}

虽然activity_new_record.xml 包含以下代码：

这是我尝试添加横幅应用程序的活动。我尝试使用测试广告单元 ID，但仍然失败。

我也想添加AndroidManifest.xml的这部分代码：

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="Anxiety Calendar"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:replace="android:label">
        <activity android:name=".Statistics"></activity>
        <!-- Include the AdActivity configChanges and theme. -->
        <activity
            android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" /> <!-- Sample AdMob App ID: ca-app-pub-3940256099942544~3347511713 -->
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-6417467530528623~3872355031" />

我该如何解决这个问题？我已经尝试了好几天...我正在使用 Galaxy Nexus API 22 模拟器。

你在你的 gradle 中添加了这个吗？

dependencies {

implementation 'com.google.android.gms:play-services-ads:19.0.0'
}

和

String myid=getString(R.string.appid);
MobileAds.initialize(this, myid);
//myid is ca-app-pub-3940256099942544/6300978111
mAdView = findViewById(R.id.adView);

AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
mAdView.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
    // Code to be executed when an ad finishes loading.
}
@Override
public void onAdOpened() {
    // Code to be executed when an ad opens an overlay that
    // covers the screen.
}
});

我想你忘了添加这一行

String myid=getString(R.string.appid);
MobileAds.initialize(this, myid);
