title: android:clickable="true" mean's that it's not clickable?
body: <p>I have a ListView with some custom sections in it. Each section has it's own header View. I want the elements in the list to be clickable, but obviously do not want the section headers to be clickable. So in the xml for the section headers I added <code>android:clickable="false"</code>.</p>
  
  <p>When debugging I noticed that the section headers were still responding to my <code>setOnItemClickListener()</code>. Then I tried setting <code>android:clickable="true"</code> in the XML. And sure enough, the section header views no longer respond to the clicks...</p>
  
  <p>So what is the deal here? Why is it that setting <code>clickable</code> = <code>true</code> telling it that it is <strong>NOT</strong> clickable? Am I misunderstanding something here? Here is my XML:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;TextView
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/item_text"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:textColor="@color/black"
      android:background="@android:color/transparent"
      android:textAppearance="?android:attr/textAppearanceLarge"
      android:paddingLeft="30dp"
      android:clickable="true" /&gt;
  </code></pre>
  
  <p>If I set that <code>clickable="false"</code> at the bottom, then this view begins to respond to the <code>setOnItemClickListener()</code>...</p>
