Set View Width Programmatically

I am trying to set the width and height of a view in code to show an ad for a free app I am working on. All of the UI is done in XML with the exception of this ad. Here is the code that displays the ad. It is in onCreate.

AdView adView = new AdView(this,"ad_url","my_ad_key",true,true);
LinearLayout layout = (LinearLayout) findViewById(R.id.testing);
adView.setAdListener(this);
layout.addView(adView);

This results in the ad being displayed like this. As you can see the width doesn't quite fill the whole page.

Now when I change the code to this to attempt to set the size:

AdView adView = new AdView(this,"ad_url","my_ad_key",true,true);
LinearLayout layout = (LinearLayout) findViewById(R.id.testing);
adView.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                       LayoutParams.WRAP_CONTENT));
adView.setAdListener(this);
layout.addView(adView);

I get this:

I have tried all different combinations of FILL_PARENT and WRAP_CONTENT all with the same result. Is there something I am missing? Or another way I can have the ad fill the width of the device without filling the height? Any suggestions and help is greatly appreciated.

EDIT when I try to put it in XML I get an exception:

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:id="@+id/main_layout">

<fragment
    android:name="com.jasoncrosby.app.tipcalculatorfree.MainButtonFragment"
android:id="@+id/button_frag"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>
<com.adsdk.sdk.banner.AdView
    android:id="@+id/banner"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>

</LinearLayout>

This code let you fill the banner to the maximum width and keep the ratio. This will only work in portrait. You must recreate the ad when you rotate the device. In landscape you should just leave the ad as is because it will be quite big an blurred.

Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
double ratio = ((float) (width))/300.0;
int height = (int)(ratio*50);

AdView adView = new AdView(this,"ad_url","my_ad_key",true,true);
LinearLayout layout = (LinearLayout) findViewById(R.id.testing);
mAdView.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT,height));
adView.setAdListener(this);
layout.addView(adView);
