Set View Width Programmatically

Question

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>

Answer 1

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

view.getLayoutParams().width = newWidth;
