How to change ActionBar menu background color (android 4 & 5)

Background Color of menu / drop down / spinner

One of a few options:

Edit styles.xml

<resources>
<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:popupMenuStyle">@style/PopupMenu</item>
        <item name="android:popupBackground">#272727</item>
        <item name="android:itemBackground">#cc9d3e</item>
</style>

Create popup_menu.xml under res/menu/ like this:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="32dp"
android:tint="@color/timeSettings"
app:popupTheme="@style/PopupMenu">

<item
    android:id="@+id/min0"
    android:orderInCategory="100"
    android:title="0"
    app:showAsAction="never" />

</menu>

Edit popupMenu in your java-file:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_clock);

    //Time
    secBtn = (Button) findViewById(R.id.btn_sec);
    secBtn.setText("00");
    //levelBtn.setTypeface(tf1);
    secBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            PopupMenu popupMenu = new PopupMenu(MainActivityClock.this, secBtn);
            popupMenu.getMenuInflater().inflate(R.menu.popup_menu_sec, popupMenu.getMenu());
            popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(MenuItem item) {
                    //Toast.makeText(MainActivity.this, "" + item.getTitle(), Toast.LENGTH_SHORT).show();
                    secBtn.setText("" + item.getTitle());
                    workTime_sec = Integer.parseInt(item.getTitle().toString());
                    //sec = item.getTitle().toString();
                    System.out.println("workTime_sec: " + workTime_sec);
                    return true;
                }
            });
            popupMenu.show();
        }
    });
}

You can simply add the line like this:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

    <!-- To change the background of options menu-->
    <item name="android:itemBackground">*Your_color*</item>

</style>

add actionOverflowMenuStyle item to your app theme

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="actionOverflowMenuStyle">@style/CMOptionsMenu</item>
    </style>


<style name="CMOptionsMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
     <item name="android:popupBackground">your color code</item>
</style>
