title: How do I change the theme of a SettingsActivity in Android?
body: <p>TL;DR: How am I supposed to change the background of a SettingsActivity to be white or off-white to match Holo.Light? Changing the theme of the app changes the text but keeps the background as black.</p>
  
  <p>I recently changed the theme of my application from default (Holo) to Holo.Light. Everything seemed to work perfectly until I opened my SettingsActivity and was greeted by this: </p>
  
  <p><img src="https://i.stack.imgur.com/SNY5Y.png" alt="enter image description here"></p>
  
  <p>As you can see, all of the test is black on a black background. </p>
  
  <p>This is the original: </p>

  <p>I am trying to make the settingsActivity have a white background. </p>
  
  <p>I have added the following to my Manifest: </p>
  
  <pre><code>&lt;application
      ...
      android:theme="@android:style/Theme.Holo.Light" &gt;
      ...
      &lt;activity
          android:name="edu.purdue.SafeWalk.settings.SettingsActivity"
          ...
          android:theme="@android:style/Theme.Holo" &gt;
      &lt;/activity&gt;
  </code></pre>
  
  <p>However even the redundant theme setting does not help. </p>
  
  <p>Obviously it is changing the theme of the text, but not the background which leads me to believe that I have manually overridden the background color. However I have not defined a layout for this SettingsActivity and I see no XML or Java that sets the background. </p>
  
  <p>I can post whatever other relevant code here, but the source is public <a href="https://github.com/Purdue-ACM-SIGAPP/SafeWalk" rel="nofollow noreferrer">here</a>. </p>
