title: Set View Width Programmatically
body: <p>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 <code>onCreate</code>.</p>
  
  <pre><code>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);
  </code></pre>
  
  <p>This results in the ad being displayed like this. As you can see the width doesn't quite fill the whole page.</p>
  
  <p><img src="https://i.stack.imgur.com/OYMBr.png" alt="enter image description here"></p>
  
  <p>Now when I change the code to this to attempt to set the size:</p>
  
  <pre><code>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);
  </code></pre>
  
  <p>I get this:</p>
  
  <p><img src="https://i.stack.imgur.com/Q2lPO.png" alt="enter image description here"></p>
  
  <p>I have tried all different combinations of <code>FILL_PARENT</code> and <code>WRAP_CONTENT</code> 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.</p>
  
  <p><em>EDIT</em> when I try to put it in XML I get an exception:</p>
  
  <pre><code>&lt;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"&gt;
  
  &lt;fragment
      android:name="com.jasoncrosby.app.tipcalculatorfree.MainButtonFragment"
  android:id="@+id/button_frag"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"/&gt;
  &lt;com.adsdk.sdk.banner.AdView
      android:id="@+id/banner"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"/&gt;
  
  &lt;/LinearLayout&gt;
