How to use TextInputLayout in new android design library

TextInputLayout extends ViewGroup class.
So which means that you have to wrap your EditText in a TextInputLayout.

<android.support.design.widget.TextInputLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content">

     <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="hint"
        android:id="@+id/editText1" />

</android.support.design.widget.TextInputLayout>
