title: How to change radiobutton style in alertDialog
body: <p>I am working on an Android application where I would like to change the color of the RadioButton inside AlertDialogs. I want those RadioButtons to match my application theme.</p>
  
  <p>So I guessed that I should look for an Android attribute that defines the drawables of my RadioButtons and modify it inside my theme.</p>
  
  <p>First I found out that the AlertDialog uses CheckedTextView to display the RadioButton. In the layout select_dialog_singlechoice_holo.xml i found this:</p>
  
  <pre><code>&lt;CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
      ...
      android:checkMark="?android:attr/listChoiceIndicatorSingle"
      ...
  /&gt;
  </code></pre>
  
  <p>I then went to the themes.xml and looked in Holo.Light theme to find this:</p>
  
  <pre><code>&lt;item name="listChoiceIndicatorSingle"&gt;@android:drawable/btn_radio_holo_light&lt;/item&gt;
  </code></pre>
  
  <p>So in my theme i changed the latter to this:</p>
  
  <pre><code>&lt;style name="GreenTheme" parent="@android:style/Theme.Holo.Light" &gt;
  
      &lt;item name="android:listChoiceIndicatorSingle"&gt;@drawable/green_radio_button&lt;/item&gt;
  
  &lt;/style&gt;
  </code></pre>
  
  <p>Unfortunately nothing happened. </p>
  
  <p>What did I miss?</p>
