Example BindingAdapter

example.xml

<layout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    >
    <data>
        <variable
            name="model"
            type="net.sarangnamu.test.viewmodel.TestViewModel" />
        <variable
              name="list"
              type="java.util.ArrayList&lt;java.lang.String&gt;"/>
    </data>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="250dp"
        android:orientation="horizontal"
        app:bindList="@{list}"
        />
</layout>

TestViewModel.java

public class TestViewModel extends ViewModel {
  @BindingAdapter("bindList")
  public static void bindList(LinearLayout layout, ArrayList<String> list) {
    // TODO
  }
}

어노테이션에서 app:bindList 를 쓰면 워닝 발생함
