this theme:

<?xml version="1.0" encoding="utf-8"?> <resources> <!-- theme applied application or activity --> <style name="customactionbartheme"     parent="@style/theme.appcompat.light.darkactionbar">     <item name="android:actionbarstyle">@style/myactionbar</item>      <!-- support library compatibility -->     <item name="actionbarstyle">@style/myactionbar</item> </style>  <!-- actionbar styles --> <style name="myactionbar"     parent="@style/widget.appcompat.light.actionbar.solid.inverse">     <item name="android:background">@color/blue_pressed_want</item>      <item name="android:windownotitle">false</item>     <item name="android:windowactionbar">true</item>     <item name="windowactionbar">true</item>     <!-- support library compatibility -->     <item name="background">@color/blue_pressed_want</item> </style>

this main activity (oncreateoptionmenu method):

@override public boolean oncreateoptionsmenu(menu menu) {     menuinflater inflater = getmenuinflater();//getsupportmenuinflater();     getmenuinflater().inflate(r.menu.activity_main, menu);     relativelayout badgelayout = (relativelayout) menu.finditem(r.id.menu_notif).getactionview();     imageview bell= (imageview)badgelayout.findviewbyid(r.id.bell); //here error      // bell.setimageresource(r.drawable.notification);     if (sharedpreferences.contains(keynotifcount)) {         countnotif = sharedpreferences.getstring(keynotifcount, "");         mnotifcount= integer.parseint(countnotif);     }     if(mnotifcount!=0) {         textview notifcount = (textview) badgelayout.findviewbyid(r.id.actionbar_notifcation_textview);         notifcount.setvisibility(view.visible);         notifcount.settext(string.valueof(mnotifcount));         etat=true;     }     if(mnotifcount==0) {         textview notifcount = (textview) badgelayout.findviewbyid(r.id.actionbar_notifcation_textviewoff);         etat=false;     }     toast.maketext(this, "notifcount" + mnotifcount, toast.length_short).show();      bell.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             //startactivity(new intent(main.this, management.class));             displayview(4);               etat=false;              mnotifcount=0;              countnotif= string.valueof(mnotifcount);             sharedpreferences.editor editor = sharedpreferences.edit();             editor.putstring(keynotifcount, countnotif);              editor.commit();         }     });     // return true;     return super.oncreateoptionsmenu(menu);  }

here menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:background="@color/blue_pressed_want" xmlns:tools="http://schemas.android.com/tools" tools:context="com.nearby.pfe.mainactivity">  <item     android:id="@+id/menu_notif"     android:icon="@drawable/notification"     android:actionlayout="@layout/view_feed_update_count"      android:showasaction="always"     android:title="@string/notif"/>

here layout view_feed_update_count:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="48dp" android:layout_height="fill_parent" android:layout_gravity="right">  <!-- menu item image --> <imageview     android:layout_width="36dp"     android:layout_height="fill_parent"     android:clickable="true"     android:layout_alignparentright="true"     android:id="@+id/bell"      android:src="@drawable/notification" />  <!-- badge count --> <textview     android:id="@+id/actionbar_notifcation_textview"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:background="@drawable/counter_bg"     android:layout_alignparentright="true"     android:visibility="invisible"     android:paddingright="13px"     android:paddingleft="13px"     android:textcolor="#ffffff" />  <textview     android:id="@+id/actionbar_notifcation_textviewoff"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignparentright="true"     android:padding="13px"     android:layout_alignleft="@+id/actionbar_notifcation_textview"     android:layout_alignstart="@+id/actionbar_notifcation_textview" />

you haven't defined actionview attribute in items relativelayout.
