title: How to change tab image scale
body: <p>I have a tab layout with drawable resources as tab images. 
  In landscape mode everything fine. But in portrait mode images doesn't have some margin from tabs. How I can change images scale or how to set some margin to image? I don't want use fixed size, don't think that it is right way.</p>
  
  <p>Here is my layout</p>
  
  <pre><code>&lt;TabWidget
                  android:id="@android:id/tabs"
                  android:layout_width="fill_parent"
                  android:layout_height="wrap_content"
                  /&gt;
          &lt;FrameLayout
                  android:id="@android:id/tabcontent"
                  android:layout_width="fill_parent"
                  android:layout_height="fill_parent"
                  android:padding="5dp"
                  &gt;
              &lt;ListView
                      android:id="@+id/list"
                      android:layout_width="fill_parent"
                      android:layout_height="fill_parent"
                      /&gt;
          &lt;/FrameLayout&gt;
  
  
  &lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:drawable="@drawable/logo" android:state_selected="true"  /&gt;
      &lt;item android:drawable="@drawable/logo_disabled" /&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>Here is tab creation</p>
  
  <pre><code>    Drawable d = res.getDrawable(R.drawable.logos); 
      spec = tabHost.newTabSpec(1).setIndicator("", res.getDrawable(R.drawable.logos)).setContent(intent);
      tabHost.addTab(spec);
  </code></pre>
