java - Why am I getting Dark theme when I have declared it to be light? -

i'm developing app material design.

i have added toolbar activity & have set it's theme light here: app:popuptheme="@style/themeoverlay.appcompat.light", still i'm getting dark theme after running it.

here's activity_about.xml file's code:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"                 xmlns:tools="http://schemas.android.com/tools"                 xmlns:app="http://schemas.android.com/apk/res-auto"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 tools:context="com.abc.xyz.aboutactivity">      <android.support.v7.widget.toolbar         android:id="@+id/toolbar"         android:layout_width="match_parent"         android:layout_height="?attr/actionbarsize"         android:background="?attr/colorprimary"         app:layout_scrollflags="scroll|enteralways"         app:popuptheme="@style/themeoverlay.appcompat.light"/>  </relativelayout> 

here's aboutactivity.java file's code:

public class aboutactivity extends appcompatactivity {      toolbar toolbar;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_about);          spannablestring s = new spannablestring("about");         s.setspan(new typefacespan(this, "pacifico.ttf"), 0, s.length(),                 spannable.span_exclusive_exclusive);          toolbar = (toolbar) findviewbyid(r.id.toolbar);         setsupportactionbar(toolbar);          getsupportactionbar().setdisplayhomeasupenabled(true);         getsupportactionbar().settitle(s);      }      @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.menu_about, menu);         return true;     }      @override     public boolean onoptionsitemselected(menuitem item) {         // handle action bar item clicks here. action bar         // automatically handle clicks on home/up button, long         // specify parent activity in androidmanifest.xml.         int id = item.getitemid();          //noinspection simplifiableifstatement         if (id == r.id.action_settings) {             return true;         }          return super.onoptionsitemselected(item);     } } 

here's styles.xml file's code:

<resources>      <!-- base application theme. -->     <style name="apptheme" parent="theme.appcompat.light.darkactionbar">         <!-- customize theme here. -->     </style>      <style name="mymaterialtheme" parent="mymaterialtheme.base">      </style>      <style name="mymaterialtheme.base" parent="theme.appcompat.light.darkactionbar">         <item name="windownotitle">true</item>         <item name="windowactionbar">false</item>         <item name="colorprimary">@color/colorprimary</item>         <item name="colorprimarydark">@color/colorprimarydark</item>         <item name="coloraccent">@color/coloraccent</item>     </style>  </resources>
