title: Spinner with ArrayAdapter<CharSequence> doesn't display
body: <pre><code>ArrayAdapter&lt;CharSequence&gt; spinAdapterHrs;
  char[] charArrayHours =    new char[]{'0','1','2'};
  CharSequence[] charSeqArrayHrs =
          new String[]{ charArrayHours.toString() };
  spinnerLeftHrs = new Spinner( this );
  spinnerLeftHrs.setSelection( startLeftHrs );
  spinnerLeftHrs.setPrompt( "prompt" );
  spinnerLeftHrs.setOnItemSelectedListener( this );
  spinAdapterHrs = new ArrayAdapter&lt;CharSequence&gt;
          ( this,
            android.R.layout.simple_spinner_item,
            charSeqArrayHrs );
  spinnerLeftHrs.setAdapter( spinAdapterHrs );
  </code></pre>
  
  <p>This compiles okay and doesn't crash, but the root of the Spinner
  has a text/prompt of [C@4 which when selected shows an overlapping
  box with the full [C@417ca5a0.
  It does not show the usual Spinner lines.</p>
  
  <p>I had it working with Integers but wanted to save CPU time on my rotten Samsung Galaxy Ace II x; and it is a realtime app with conversions running just-about all the time (as far as the user is concerned at least).</p>
  
  <p>It's a recent Android sdk but the API target is 15.</p>
  
  <p>The environment is Ant under win 10 using TextPad.</p>
  
  <p>Hope you can help!</p>
