Data Binding

Custom Setters

I would like to custom the setter for the android:src attribute. A static binding adapter method with the BindingAdapter annotation allows me to customize how a setter for an attribute is called.

public class MyViewModel {

  @BindingAdapter("android:src")
  public static void loadImage(ImageView view, Drawable drawable) {
    GlideApp.with(view.getContext())
        .load(null)
        .placeholder(drawable)
        .into(view);
  }

}

Set image resource to TextView

TextView only receives the Drawable object, so we have to binding the resource Id to attribute of TextView.
