How to change color of toolbar options background
<p>I want to change the light background of options in the toolbar as well as the section that appears when trying to copy something. It's really bad right now:</p>

<p>Here is my styles.xml :</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
&lt;resources&gt;
  &lt;style name="MyTheme.Base" parent="Theme.AppCompat.Light.NoActionBar"&gt;
    !-- All customizations that are NOT specific to a particular API-level can go here. --&gt;
    &lt;item name="windowNoTitle"&gt;true&lt;/item&gt;
    &lt;item name="colorPrimary"&gt;@color/primary&lt;/item&gt;
    &lt;item name="colorPrimaryDark"&gt;@color/primary_dark&lt;/item&gt;
    &lt;item name="colorAccent"&gt;@color/accent&lt;/item&gt;
     &lt;item name="android:textColorPrimary"&gt;@color/primary_text&lt;/item&gt;
     &lt;item name="android:textColorSecondary"&gt;@color/secondary_text&lt;/item&gt;

  &lt;/style&gt;

  &lt;!-- Application theme. --&gt;
  &lt;style name="MyTheme" parent="MyTheme.Base"&gt;
  &lt;/style&gt;

  &lt;style name="MyTheme.ToolBar" parent="MyTheme.Base"&gt;
    &lt;item name="android:textColorPrimary"&gt;@android:color/white&lt;/item&gt;
    &lt;item name="android:textColorSecondary"&gt;@android:color/white&lt;/item&gt;
  &lt;/style&gt;

  &lt;style name="MyTheme.NavMenu" parent="MyTheme.Base"&gt;
    &lt;item name="android:textColorPrimary"&gt;@color/gray&lt;/item&gt;
  &lt;/style&gt;

  &lt;style name="MyTheme.RightMenu" parent="MyTheme.Base"&gt;
    &lt;item name="android:textColorPrimary"&gt;@color/black&lt;/item&gt;
  &lt;/style&gt;
&lt;/resources&gt;

<p>As you may have noticed I'm using <code>NoActionBar</code> because I'm using a toolbar. It's on my main.xml :</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"&gt;
&lt;!-- your content layout --&gt;
    &lt;LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"&gt;
    &lt;!-- Toolbar instead of ActionBar so the drawer can slide on top --&gt;
        &lt;android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            app:theme="@style/MyTheme.ToolBar"
            android:layout_width="match_parent"
            android:layout_height="@dimen/abc_action_bar_default_height_material"
            android:background="?attr/colorPrimary"
            android:minHeight="?attr/actionBarSize" /&gt;
    &lt;!-- Real content goes here --&gt;
        &lt;FrameLayout
            android:id="@+id/content_frame"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1" /&gt;
    &lt;/LinearLayout&gt;
    &lt;android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:id="@+id/nav_view"
        app:headerLayout="@layout/nav_view_header"
        app:menu="@layout/nav_view_menu"
        app:theme="@style/MyTheme.NavMenu" /&gt;
&lt;/android.support.v4.widget.DrawerLayout&gt;
