title: Focusable EditText inside ListView
body: <p>I've spent about 6 hours on this so far, and been hitting nothing but roadblocks.  The general premise is that there is some row in a <code>ListView</code> (whether it's generated by the adapter, or added as a header view) that contains an <code>EditText</code> widget and a <code>Button</code>.  All I want to do is be able to use the jogball/arrows, to navigate the selector to individual items like normal, but when I get to a particular row -- even if I have to explicitly identify the row -- that has a focusable child, I want that child to take focus instead of indicating the position with the selector.</p>
  
  <p>I've tried many possibilities, and have so far had no luck.</p>
  
  <p>layout:</p>
  
  <pre><code>&lt;ListView
      android:id="@android:id/list" 
      android:layout_height="fill_parent" 
      android:layout_width="fill_parent"
      /&gt;
  </code></pre>
  
  <p>Header view:</p>
  
  <pre><code>EditText view = new EditText(this);
  listView.addHeaderView(view, null, true);
  </code></pre>
  
  <p>Assuming there are other items in the adapter, using the arrow keys will move the selection up/down in the list, as expected;  but when getting to the header row, it is also displayed with the selector, and no way to focus into the <code>EditText</code> using the jogball.  Note: tapping on the <code>EditText</code> <em>will</em> focus it at that point, however that relies on a touchscreen, which should not be a requirement.</p>
  
  <p><code>ListView</code> apparently has two modes in this regard:<br>
  1. <code>setItemsCanFocus(true)</code>: selector is never displayed, but the <code>EditText</code> can get focus when using the arrows.  Focus search algorithm is hard to predict, and no visual feedback (on any rows: having focusable children or not) on which item is selected, both of which can give the user an unexpected experience.<br>
  2. <code>setItemsCanFocus(false)</code>: selector is always drawn in non-touch-mode, and <code>EditText</code> can never get focus -- even if you tap on it.</p>
  
  <p>To make matters worse, calling <code>editTextView.requestFocus()</code> returns true, but in fact does not give the EditText focus.</p>
  
  <p>What I'm envisioning is basically a hybrid of 1 &amp; 2, where rather than the list setting if <em>all</em> items are focusable or not, I want to set focusability for a <em>single</em> item in the list, so that the selector seamlessly transitions from selecting the entire row for non-focusable items, and traversing the focus tree for items that contain focusable children.</p>
  
  <p>Any takers?</p>
