Different scale type for place holder and image

Question

I want fitXY scaleType for image and fitCenter for place holder. I am fetching data from api using volley and loading image using glide. How am I supposed to know that image is null ?

XML and code

<ImageView
    android:id="@+id/NewsImage"
    android:layout_width="120dp"
    android:layout_height="120dp"
    android:scaleType="fitCenter" />

Glide.with(context).load(news.getUrlToImage()).placeholder(R.drawable.place_holder).dontAnimate().into(holder.NewsImage);

1.USING LISTENER

Using GLIDE you can add a listener for image loading. Once the image is loaded change the SCALE type of the ImageView.

Glide.with(getActivity())
 .load(args.getString(IMAGE_TO_SHOW))
 .listener(new RequestListener<String, GlideDrawable>() {
     @Override
     public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
         return false;
     }

     @Override
     public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
         imgview.setScaleType(ImageView.ScaleType.FIT_XY);
         return false;
     }
 })
 .into(imgview)

2.USING GLIDE

You can use one of the GLIDE transformations for the image or create your custom transformation https://github.com/bumptech/glide/wiki/Transformations
