问题 I want to create an "inflateWhen" BindingAdapter and attach it to a viewstub to have it inflate when a boolean value is true. However, the BindingAdapter keeps trying to operate on the root view of the viewstub, causing it to fail to compile.

问题 Suppose I have a custom setter method where I need two arguments: @BindingAdapter({"imageUrl", "placeholder"}) public static void loadImage(ImageView imageView, String imageUrl, Drawable drawable) { Picasso.with(imageView.getContext()).load(imageUrl).placeholder(drawable).into(imageView); } What would the corresponding xml look like? 回答1: Looks like it can be done like this: <ImageView app:imageUrl=“@{data.imageUrl}” app:placeholder=“@{@drawable/placeholder}”/> see http://developer.android
