I am trying to create a badge like view in the Action bar. (Using the latest support library).
I am trying the following way. But its saying null pointer exception.
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.activity_dashboard_menu, menu);
MenuItem textBadge = menu.findItem(R.id.badge);
RelativeLayout badgeLayout = (RelativeLayout) MenuItemCompat.getActionView(textBadge);
TextView tv = (TextView) badgeLayout.findViewById(R.id.actionbar_notifcation_textview);
tv.setText("12");
return super.onCreateOptionsMenu(menu);
}
Menu.xml is
<item
android:id="@+id/badge"
android:actionLayout="@layout/actionbar_badge_layout"
android:icon="@drawable/btn_star_off_disabled_holo_light"
android:showAsAction="always|withText">
</item>
and the Layout.xml is
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="48dp"
android:layout_height="fill_parent"
android:layout_gravity="right" >
<!-- Menu Item Image -->
<ImageView
android:layout_width="48dp"
android:layout_height="fill_parent"
android:clickable="true"
android:src="@drawable/btn_star_off_disabled_holo_light" />
<!-- Badge Count -->
<TextView
android:id="@+id/actionbar_notifcation_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:padding="5dp"
android:text="99"
android:textColor="#ffffff" />
</RelativeLayout>
And here is my Log:

Thank you beworker for your help.
For all those who are looking for answer.
Its in the Menu XML thats causing the Null Pointer Exception. Changed android:actionLayout to app:actionLayout.
Earlier:
<item
android:id="@+id/badge"
android:actionLayout="@layout/actionbar_badge_layout"
android:icon="@drawable/btn_star_off_disabled_holo_light"
android:showAsAction="always|withText">
Changed to:
<item
android:id="@+id/badge"
yourapp:actionLayout="@layout/actionbar_badge_layout"
android:icon="@drawable/btn_star_off_disabled_holo_light"
yourapp:showAsAction="always|withText">
