大家好，我在我的一个应用程序中使用 MMAdView，它在除 SAMSUNG S3 之外的所有设备中都运行良好，为什么会发生这种情况，对这个问题有任何想法。

这里附有屏幕短片

这个 480x800 Htc 设备

在此处输入图像描述

这里是三星 s3 设备 720x1280 在此处输入图像描述

IN 三星 s3 设备右侧角落的空白区域。

这是我正在使用的代码。

活动代码

public class MainActivity extends Activity { 

private static final int MED_BANNER_WIDTH = 480;
private static final int MED_BANNER_HEIGHT = 60;

//Constants for phone sized ads (320x50)
private static final int BANNER_AD_WIDTH = 320;
private static final int BANNER_AD_HEIGHT = 50;

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

    Log.i("MainActivity", "one");    

    int placementWidth = BANNER_AD_WIDTH;
    int placementHeight = BANNER_AD_HEIGHT;

    //Finds an ad that best fits a users device.
    if(canFit(BANNER_AD_WIDTH)) {
        Log.i("MainActivity", "two");
        placementWidth = BANNER_AD_WIDTH;
        placementHeight = BANNER_AD_HEIGHT;
    } else if(canFit(MED_BANNER_WIDTH)) {
        Log.i("MainActivity", "three");
        placementWidth = MED_BANNER_WIDTH;
        placementHeight = MED_BANNER_HEIGHT;
    }       

    MMAdView adView = new MMAdView(this);        
    adView.setApid("Appid");     
    MMRequest request = new MMRequest();         
    adView.setMMRequest(request);    
    adView.setId(MMSDK.getDefaultAdId());            
    adView.setWidth(placementWidth);
    adView.setHeight(placementHeight);

    //Calculate the size of the adView based on the ad size. Replace the width and height values if needed.
    int layoutWidth = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, placementWidth, getResources().getDisplayMetrics());
    int layoutHeight = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, placementHeight, getResources().getDisplayMetrics());

    //Create the layout parameters using the calculated adView width and height.
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(layoutWidth, layoutHeight);

    //This positions the banner.
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);

    adView.setLayoutParams(layoutParams);
    adView.getAd();     
    Log.i("MainActivity", "four");

    RelativeLayout layout = (RelativeLayout) findViewById(R.id.adBannerRelativeLayout);
    //Add the adView to the layout. The layout is assumed to be a RelativeLayout.
    layout.addView(adView);
}

protected boolean canFit(int adWidth) {

    Log.i("MainActivity", "five");
    int adWidthPx = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 
            adWidth, getResources().getDisplayMetrics());
    DisplayMetrics metrics = this.getResources().getDisplayMetrics();
    Log.i("MainActivity", " metrics==> "+ metrics);
    return metrics.widthPixels >= adWidthPx;
}
 }

这是 XML 文件

      <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:mm="http://millennialmedia.com/android/schema"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content" >

<RelativeLayout
    android:id="@+id/adBannerRelativeLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

</RelativeLayout>

EDIT:这是我正在使用MAdView的文档
