[android] 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>

hsThumbList.setLayoutParams(new LayoutParams(100, 400));

You can use something like code below, if you need to affect only specific value, and not touch others:

view.getLayoutParams().width = newWidth;

yourView.setLayoutParams(new LinearLayout.LayoutParams(width, height));

in code add below line:

spin27.setLayoutParams(new LinearLayout.LayoutParams(200, 120));

check it in mdpi device.. If the ad displays correctly, the error should be in "px" to "dip" conversion..

The first parameter to LayoutParams is the width and the second is the height. So if you want the width to be FILL_PARENT, but the width to be, say, 20px, then use something new LayoutParams(FILL_PARENT, 20). Of course you should never use actual pixels in your code; you'll need to conver that to density-independent pixels, but you get the idea. Also, you need to make sure your parent LinearLayout has the right width and height that you're looking for. Seems to be you want the LinearLayout to fill the parent width-wise and then have the adview fill that linearlayout witdh-wise as well, so you probably need to specify android:layout_width:"fill_parent" and android:layout_height:"wrap_content" in your linear layout's xml.
