Android binding adapter passing multiple arguments cause error

Question

I am quite new in Android Data Binding. I am following this tutorial: Data Binding Library. I am trying to do an adapter that receive multiple parameters. This is my code:

XML

   <ImageView
            android:layout_width="@dimen/place_holder_size"
            android:layout_height="@dimen/place_holder_size"
            android:layout_alignParentRight="true"
            android:layout_alignParentTop="true"
            android:layout_centerVertical="true"
            app:url="@{image.imageUrl}"
            app:size="@{@dimen/place_holder_size}"
            />

BINDING ADAPTER CLASS

public class ViewBindingAdapters extends BaseObservable {

@BindingAdapter({"bind:url", "bind:size"})
public static void loadImage(ImageView imageView, String url, int size) {
    if (!Strings.isNullOrEmpty(url)) {
        Picasso.with(imageView.getContext()).load(url).resize(size, size).centerCrop().into(imageView);
    }
}
....


}

But I am getting this error:

java.lang.RuntimeException: Found data binding errors. ****/ data binding error ****msg:Cannot find the setter for attribute 'app:url' with parameter type java.lang.String on android.widget.ImageView. file:... li_image_item.xml loc:30:27 - 30:40 ****\ data binding error ****

Does anybody know why??

Thanks in advance!

Answer 1

Problem is @dimen/place_holder_size, it returns float while you are catching it as int

change you BindingAdapter method to this

@BindingAdapter({"bind:url", "bind:size"})
public static void loadImage(ImageView imageView, String url, float size) {

}
