title: clicking on the fragment invokes activity behind it
body: <p>Im guessing its something really simple, maybe a setting in listview or fragment.
  But I couldnt find solution for it for couple of hours now.
  So..
  I have a listView like this</p>
  
  <pre><code>&lt;RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/content"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:isScrollContainer="true"&gt;
  
  &lt;ListView 
      android:id="@+id/list"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:background="#fffafa"
      /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>when someone clicks on the list item. I replace it with a fragment like this</p>
  
  <pre><code>    FragmentManager manager = getSupportFragmentManager();
      FragmentTransaction ft = manager.beginTransaction();
      ft.replace(R.id.content, newFragment);
  
      ft.addToBackStack(null);
      ft.commit();
  </code></pre>
  
  <p>If I click on the item on the List, The whole list is replaced with a fragment(*) consisting of a Button and and couple of text fields.
  The Fragment replaces the listView properly with information about the item. When I press back it does properly bring the list view back.</p>
  
  <p>The problem is that if i click on the background of the * it behaves as if I would click on the list that is behind it.. and brings fragment about that item to the front. I can click endlessly on background to bring other fragments. I can dig back to list by clicking back,back..</p>
  
  <p>Why this fragment is transparent? how can i fix this?</p>
