Question

我制作了Flappy Bird翻拍，不久前我就完成了它，一切都按预期工作，但当我尝试添加Google的广告时，广告会显示，但游戏无法执行和运行，它是只是一个黑屏。我也在为我的游戏使用LibGDX。这是MainActivity.java代码和Main.xml代码。

MainActivity.java：

    package com.kensleeinc.SuperBird;

import android.os.Bundle;

import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import com.kilobolt.ZombieBird.R;
import com.kilobolt.ZombieBird.ZBGame;

public class MainActivity extends AndroidApplication 
{
    private AdView adView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
        cfg.useGL20 = false;

        initialize(new ZBGame(), cfg);

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        AdView adView = (AdView)this.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
    }
}

Main.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        ads:adSize="BANNER"
        ads:adUnitId="@string/ad_unit_id"/>

</RelativeLayout>

任何人都可以帮我吗？谢谢！

您的异常是由两次super.onCreate(savedInstanceState);

调用引起的

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);  //Here ***

        AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
        cfg.useGL20 = false;

        initialize(new ZBGame(), cfg);

        super.onCreate(savedInstanceState); //and Here ***
        setContentView(R.layout.main);
        AdView adView = (AdView)this.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
    }

您的onCreate()方法必须类似于：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main);

        AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
        cfg.useGL20 = false;    
        initialize(new ZBGame(), cfg);

        AdView adView = (AdView)this.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
    }

我修好了，就是广告试图覆盖游戏显示，因此一个会显示而另一个则不显示。这是我为LibGDX工作的onCreate方法。

public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
       cfg.useGL20 = false;
       //setContentView(R.layout.main);
       RelativeLayout layout = new RelativeLayout(this);
       RelativeLayout.LayoutParams gameViewParams =
               new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, 
                       RelativeLayout.LayoutParams.WRAP_CONTENT);
       //gameViewParams.bottomMargin = 150;
       requestWindowFeature( Window.FEATURE_NO_TITLE );
       View gameView = initializeForView(new ZBGame(), cfg);
       layout.addView(gameView, gameViewParams);

       AdView adView = new AdView(this);
       adView.setAdUnitId("my-ad-unit-here");
       adView.setAdSize(AdSize.BANNER);

       RelativeLayout.LayoutParams adParams = 
           new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, 
                   RelativeLayout.LayoutParams.WRAP_CONTENT);
       adParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
       adParams.addRule(RelativeLayout.CENTER_HORIZONTAL);

       layout.addView(adView, adParams);

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

       setContentView(layout);    
    }
