          &lt;!-- Customize your theme here. --&gt;
          &lt;item name="windowNoTitle"&gt;true&lt;/item&gt;
          &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
          &lt;item name="android:windowFullscreen"&gt;true&lt;/item&gt;
          &lt;item name="android:windowContentOverlay"&gt;@null&lt;/item&gt;
