[android-developers] Databinding. How to create anonymous class instance inside tag?

[Alexandr Bobro]

Are there any experts in databinding? I've read all articles that I've 
found but haven't find an answer...

For example I have next layout:

<layout xmlns:android="http://schemas.android.com/apk/res/android";>
    <data>
        <variable
            name="focusChangeListener"
            type="android.view.View.OnFocusChangeListener" />
    </data>

    <EditText
        android:id="@+id/entry"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:onFocusChange="@{focusChangeListener}"/>
</layout>


And I want to include it into another one like that : 

<layout xmlns:android="http://schemas.android.com/apk/res/android";
    xmlns:bind="http://schemas.android.com/apk/res-auto";>
    <data>
        <variable
            name="listener"
            
type="com.netpulse.mobile.register.view.actionlisteners.EmailFieldActionListener"
 />
    </data>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <include layout="@layout/edittext"
            bind:focusChangeListener="@{(v,hasFocus) -> 
listener.onEmailFocusChanged(hasFocus)}"/>

    </LinearLayout>
</layout>


But construction like (v,hasFocus) -> listener.onEmailFocusChanged(hasFocus)  
doesn't work inside <include>. 
I want to receive something similar to 
that 
https://github.com/googlesamples/android-architecture/blob/todo-databinding/todoapp/app/src/main/res/layout/taskdetail_frag.xml#L74
 
but for <include>

Is there any way to do something with that?
