Android change background color of popup menu

Question

I don't understand why is so painful to change a color for an android app. I tried several ways to change the background color of the popup menu in my action bar with no success.

I'm using a AppTheme.NoActionBar to style, obviously, the action bar.

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="navigationIcon">@drawable/ic_return_dark</item>
    <item name="overlapAnchor">false</item>
    <item name="popupMenuStyle">@style/PopupMenu</item>
</style>

<style name="PopupMenu" parent="Widget.AppCompat.PopupMenu">
    <item name="android:popupBackground">@color/color4</item>
</style>

Following the examples that I found, there was this explanation that you need to insert in your custom style (in my case AppTheme.NoActionBar) a custom popupMenuStyle in order to custom the popupBackground, which changes the background color of popup menu. It doesn't work.

What can I do to change the background color of popup menu?

To change the color of the Options Menu in Android, changing themes and styles won't help. You have to initialise LayoutInflater Factory Class.

   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
   MenuInflater inflater = getMenuInflater();
   inflater.inflate(R.menu.my_menu, menu);
   getLayoutInflater().setFactory(new Factory() {
   @Override
   public View onCreateView(String name, Context context,
   AttributeSet attrs) {
   if (name .equalsIgnoreCase(“com.android.internal.view.menu.IconMenuItemView”)) {
   try {
   LayoutInflater f = getLayoutInflater();
   final View view = f.createView(name, null, attrs);
   new Handler().post(new Runnable() {
   public void run() {

   view.setBackgroundResource(R.drawable.your_color);

   ((TextView) view).setTextColor(Color.your_color);
   }
   });
   return view;
   } catch (InflateException e) {
   } catch (ClassNotFoundException e) {
   }
   }
   return null;
   }
   });
   return super.onCreateOptionsMenu(menu);
   }
