You need to include <data> inside your <layout>:

<layoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/tools"><data></data><LinearLayoutandroid:orientation="vertical"android:layout_width="match_parent"android:layout_height="wrap_content"><TextViewandroid:id="@android:id/text1"android:layout_width="match_parent"android:layout_height="wrap_content"app:attribute="name"/></LinearLayout></layout>

On a side note, classpath 'com.android.databinding:dataBinder:1.0-rc4' and apply plugin: 'com.android.databinding' are no more needed if you are using gradle version 2.+.
