title: android:digits Problem
body: <p>I am using the following xml to limit input to digits only in an EditText widget. The android:digits attribute uses the below array resource. Everything works great except for the fact that I can't enter the number 4 even though its in the array. Any Ideas? </p>
  
  <pre><code>&lt;EditText
      android:id="@+id/mynumber"  
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"
      android:textSize="40dp"
      android:textStyle="bold"
      android:gravity="center_horizontal"
      android:layout_centerHorizontal="true"
      android:textColor="#aaffaa"
      android:numeric="integer"
      android:digits="@array/digits"
      android:background="#00000000"
      android:inputType="phone"
      android:focusable="true"
      android:singleLine="true" /&gt;
  </code></pre>
  
  <p>String array resource excerpt:</p>
  
  <pre><code>&lt;string-array name="digits"&gt;
    &lt;item&gt;0&lt;/item&gt;
    &lt;item&gt;1&lt;/item&gt;
    &lt;item&gt;2&lt;/item&gt;
    &lt;item&gt;3&lt;/item&gt;
    &lt;item&gt;4&lt;/item&gt;
    &lt;item&gt;5&lt;/item&gt;
    &lt;item&gt;6&lt;/item&gt;
    &lt;item&gt;7&lt;/item&gt;
    &lt;item&gt;8&lt;/item&gt;
    &lt;item&gt;9&lt;/item&gt;
  &lt;/string-array&gt;
  </code></pre>
