title: How to control header height in Android app?
body: <p>I have an older app that I am porting. In the app I had a non-standard header navigation made up of images and text over them.</p>
  
  <p>The images used to be square, but there was some way I was able to make them rectangular by limiting the height of the header on the page. </p>
  
  <p>I can't figure out how to do that. Where should I have such a setting and how should it look like?</p>
  
  <p>Here is my header file</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content"
   android:orientation="horizontal"
  &gt;
  
   &lt;Button android:id="@+id/home_header"
    android:layout_width="0dp" 
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:textColor="@color/white"
    android:text="Home"
    android:background="@drawable/ic_menu_not"
    android:textSize="11dp"
  /&gt; 
  
  
  
   &lt;Button android:id="@+id/learn_header"
    android:layout_width="0dp" 
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Learn"
    android:textColor="@color/white"
    android:textSize="11dp"
    android:background="@drawable/ic_menu_not"
    android:layout_toRightOf="@+id/businesses_header"
   /&gt;   
  
  
  &lt;Button android:id="@+id/questions_header"
   android:layout_width="0dp" 
   android:layout_height="wrap_content"
   android:textColor="@color/white"
   android:layout_weight="1"
   android:text="Plans"
   android:textSize="11dp"
     android:background="@drawable/ic_menu_not"
  android:layout_toRightOf="@+id/learn_header"  /&gt;  
  
  
  
   &lt;Button android:id="@+id/extra_help_header"
    android:layout_width="0dp" 
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:textColor="@color/white"
    android:text="More Help"
    android:textSize="11dp"
    android:background="@drawable/ic_menu_not"
    android:layout_toRightOf="@+id/questions_header"
   /&gt;   
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>and I include that header in screens like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:background="#1BB5E0"
          &gt;
  &lt;include android:id="@+id/header"
           layout="@layout/header"
           android:layout_height="wrap_content"
           android:layout_width="fill_parent"/&gt;  
  </code></pre>
  
  <p>How can I decrease the height of the header by about 50%? </p>
