You can include the viewModel in <include> layouts too.

[izyaboi]

but how? i have this

[izyaboi]

<data>
    <import type="android.view.View" />

    <variable
        name="dataContext"
        type="canvasm.myo2.usagemon.MobileUsageNationalViewModel" />
</data>

and this

<include
    android:id="@+id/additional_item_top"
    layout="@layout/o2theme_usagemon_additional_item_top"
    bind:dataContext="@{dataContext}"/>

and the include have this

[izyaboi]

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:app="<http://schemas.android.com/apk/res-auto>">
    <data>
        <variable
            name="dataContext"
            type="canvasm.myo2.usagemon.MobileUsageNationalViewModel" />
    </data>

    <LinearLayout xmlns:android="<http://schemas.android.com/apk/res/android>"
        xmlns:tools="<http://schemas.android.com/tools>"
        android:id="@+id/additional_info_layout_top"
        app:visibleOrGone="@{dataContext.isAdditionalTopInfo}"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginBottom="5dp"
        android:orientation="vertical">

        <TextView
            style="@style/sg.label.with_horizontal_spacing"
            android:id="@+id/um_top_additional_info"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:gravity="center_horizontal"
            android:text ="@{dataContext.additionalTopInfo}"
            tools:text="Info Text hier"
            tools:visibility="visible"
            android:visibility="gone" />

</LinearLayout>
</layout>

bind:dataContext try replacing this with app:dataContext

[izyaboi]

that makes no difference i got this

[izyaboi]

D:\dev\android_b2c_app\app\build\generated\source\kapt\fl_o2Debug\canvasm\myo2\DataBinderMapperImpl.java:334: error: cannot find symbol
import canvasm.myo2.databinding.O2themeUsageMobileNationalBindingImpl;
                               ^
  symbol:   class O2themeUsageMobileNationalBindingImpl

[izyaboi]

in onCreateView in my fragment i make this

viewDataBinding = O2themeUsageMobileNationalBinding.inflate(inflater, container, false)
    .apply { dataContext = viewModel }

[Gokul]

Make sure you have

xmlns:app="<http://schemas.android.com/apk/res-auto>"

in your parent <layout>

[izyaboi]

all there

[izyaboi]

@George Mount or @yigit can u help

[yigit]

sorry saw this late but the include looks fine, probably there is some other error that breaks O2themeUsageMobileNationalBindingImpl code generation hence the other error is received

[yigit]

there should be something else about O2themeUsageMobileNationalBindingImpl in the error logs
