title: Incorrect styling AlertDialog on Android API 19
body: <p>I'm trying to style an AlertDialog. It works fine on API  23 and 24, but on 19 it doesn't. Here is what it should look like:</p>
  
  <p><a href="https://i.stack.imgur.com/A4IaP.png" rel="nofollow noreferrer">Correct</a></p>
  
  <p>And what it looks like on API 19:</p>
  
  <p><a href="https://i.stack.imgur.com/EMjn4.png" rel="nofollow noreferrer">Incorrect</a></p>
  
  <p>I can't find any information on what items I have to edit to change those black colors, or remove that light blue line, or that extra shadow that shouldn't be there, or even a list of the style items that apply to an AlertDialog. Here is what my style looks like. I added a bunch of items that I probably don't need as I was trying to fix this.</p>
  
  <pre><code>    &lt;style name="AlertDialogTheme" parent="Base.Theme.AppCompat.Dialog.Alert"&gt;
      &lt;item name="colorPrimary"&gt;#ffffffff&lt;/item&gt;
      &lt;item name="colorPrimaryDark"&gt;#ffffffff&lt;/item&gt;
      &lt;item name="colorAccent"&gt;#ffffffff&lt;/item&gt;
      &lt;item name="android:actionModeBackground"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="android:textColor"&gt;#ffffffff&lt;/item&gt;
      &lt;item name="android:textColorPrimary"&gt;#ffffffff&lt;/item&gt;
      &lt;item name="android:background"&gt;#ff005e9e&lt;/item&gt;
      &lt;item name="actionModeBackground"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="actionButtonStyle"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="actionBarItemBackground"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="background"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="android:colorBackground"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="android:colorBackgroundCacheHint"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="colorBackgroundFloating"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="colorControlNormal"&gt;#ff005e9e&lt;/item&gt;
      &lt;item name="colorControlActivated"&gt;#ff005e9e&lt;/item&gt;
      &lt;item name="colorControlHighlight"&gt;#30FFFFFF&lt;/item&gt;
      &lt;item name="android:windowBackground"&gt;@color/dialogBackground&lt;/item&gt;
      &lt;item name="android:shadowColor"&gt;@color/dialogBackground&lt;/item&gt;
  &lt;/style&gt;

  <p>I need some help figuring out what setting I have to change here.</p>
  
  <p>Thanks in advance.</p>
