ライブ壁紙設定アクティビティを作成しています。いくつかのシークバーとAdMob広告ビューがあります。シークバーの1つに触れるたびに、広告は一時的に消えてから、新しい追加をリロードします。ただし、他の設定に触れても広告は変更されません。シークバーの設定に触れたときに広告が再読み込みされないようにするにはどうすればよいですか？私はこれにかなり困惑しています:-)。コードは次のとおりです。

広告設定クラス：

import android.app.Activity;
import android.content.Context;
import android.preference.Preference;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;

import com.google.ads.AdRequest;
import com.google.ads.AdSize;
import com.google.ads.AdView;

public class AdPreference extends Preference {

    public AdPreference(Context context, AttributeSet attrs, int defStyle) {super    (context, attrs, defStyle);}
    public AdPreference(Context context, AttributeSet attrs) {super(context, attrs);}
    public AdPreference(Context context) {super(context);}

    @Override
    protected View onCreateView(ViewGroup parent) {
        // this will create the linear layout defined in ads_layout.xml
        View view = super.onCreateView(parent);

        // the context is a PreferenceActivity
        Activity activity = (Activity)getContext();

        // Create the adView
        AdView adView = new AdView(activity, AdSize.BANNER, "a151390e12917b5");

        ((LinearLayout)view).addView(adView);

        // Initiate a generic request to load it with an ad
        AdRequest request = new AdRequest();
        request.addTestDevice("23392C83B8B55DE893A18286CB92DDA2");
        request.addTestDevice("E1BAA0317138AEE05268B2E4F76B2D3F");
        adView.loadAd(request);     

        return view;    
    }
}

onCreateViewは複数回呼び出されるので、毎回広告リクエストが作成されると思います。AdMobコードをonBindやonAttachedなどに移動してみてください。
