Display default text in a SpinnerAdapter (For an ActionBar navigation)
<p>I've had a look at the documentation, but I'm not sure what would be the best way to approach this.</p>

<p>This is what I'm doing:</p>

<pre><code>mActionBar = getActionBar();
mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);

SpinnerAdapter mSpinnerAdapter = ArrayAdapter.createFromResource(this,
            R.array.platform_list,
            android.R.layout.simple_spinner_dropdown_item);
</code></pre>

<p>What I'm trying to do is give the dropdown list a default value - "Please Select a Type", when the application loads up and nothing is selected yet. This is because the selection will trigger a change in the listview fragment displayed below, and without a selection (at startup) i would like to display a simple placeholder image or something.</p>

<p>Any ideas? Thanks a lot in advance!</p>
