I had this menu xml that works fine:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:id="@+id/context_menu_save"
android:actionViewClass="my.app.TextViewPlus"
android:showAsAction="always"
android:title="@string/logout"
android:visible="false"/>
</menu>
But when i started using AppComap v7 i hade null exception when using getActionView()
.
I change my menu layout to:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:myapp="http://schemas.android.com/apk/res-auto" >
<item
android:id="@+id/context_menu_save"
myapp:actionViewClass="my.app.TextViewPlus"
myapp:showAsAction="always"
android:title="@string/logout"
android:visible="false"/>
</menu>
And now it works fine. Can anyone explain, why is it happens?

In Android Studio v1.5, I see the following message for this scenario:
When using the appcompat library, menu resources should refer to the app: namespace, not the android: namespace.
When not using the appcompat library, you should be using the android: namespace.

xmlns:myapp this is used when you create your own (or use others) customized views.
xmlns:android this is used when default android views.
so as ur question, i hope ur using your own (or use others) customized views. so u got error.
