android - Ripple effect using itemBackground on NavigationView -

-

i wonder if having problems when redefining background of items on navigationview app:itembackground"? behavior shown on screenshot, no matter item press last item shows ripple instead.

here drawer_menu.xml:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android">      <group android:checkablebehavior="single" android:id="@+id/first_group">         <item             android:id="@+id/nav_home"             android:icon="@drawable/ic_home"             android:title="@string/nav_home" />     </group>      <group android:id="@+id/second_group">         <item             android:id="@+id/nav_settings"             android:title="@string/nav_settings" />         <item             android:id="@+id/nav_about"             android:title="@string/nav_about" />         <item             android:id="@+id/nav_logout"             android:title="@string/nav_logout" />     </group>  </menu>

my my_ripple.xml:

<ripple xmlns:android="http://schemas.android.com/apk/res/android"         android:color="#ffff0000">     <item         android:id="@android:id/mask"         android:drawable="@android:color/white" /> </ripple>

my navigationview:

<android.support.design.widget.navigationview     android:id="@+id/navigation_view"     android:layout_width="wrap_content"     android:layout_height="match_parent"     android:layout_gravity="start"     android:background="@android:color/white"     app:headerlayout="@layout/drawer_header"     app:itembackground="@drawable/my_ripple"     app:itemicontint="@color/drawer_item"     app:itemtextcolor="@color/drawer_item"     app:menu="@menu/drawer_menu" />

ripple fail

apply itembackground attribute menu rather navigationview. ripple stay contained menu item handling touch event.
