Set visibility of progress bar gone on completion of image loading using Glide library

Question

Hi I want to have a progress bar for image which will shown while image loading but when image loading will be completed I want to set it to gone. Earlier I was using Picass

Answer 1

This is the best answer as it does not use any hack like setting visibility to get the desired output.

Download a gif of progressbar and call it progressbargif and put it in the drawable folder.

        Glide.with(ctx)
            .load(url)
            .thumbnail(Glide.with(ctx).load(R.drawable.progressbargif))
            .diskCacheStrategy(DiskCacheStrategy.SOURCE)
            .error(R.drawable.image_unavailable)
            .crossFade(200)
            .into(iv);

Once the url image is loaded, the thumbnail vanishes. The thumbnail vanishes immediately when the cached image is loaded.

Answer 2

How I did things. the shorter way, cleaner code

example:

progress_bar.visibility = View.VISIBLE

profilePicturePath?.let {
    GlideApp.with(applicationContext)
        .load(CloudStorage.pathToReference(it))
        .placeholder(R.drawable.placeholder)
        .listener(GlideImpl.OnCompleted {
            progress_bar.visibility = View.GONE
        })
    .into(profile_picture)
} ?: profile_picture.setImageResource(R.drawable.placeholder)

usage:

GlideImpl.OnCompleted {
    // completed
}

just pass GlideImpl.OnCompleted { } to the Glide's .listener()

GlideImpl.kt class that accepts Glide's RequestListener

import android.graphics.drawable.Drawable
import com.bumptech.glide.load.DataSource
import com.bumptech.glide.load.engine.GlideException
import com.bumptech.glide.request.RequestListener
import com.bumptech.glide.request.target.Target

object GlideImpl {

    object OnCompleted : RequestListener<Drawable> {

        private lateinit var onComplete: () -> Unit

        operator fun invoke(onComplete: () -> Unit): OnCompleted {
            OnCompleted.onComplete = { onComplete() }
            return this
        }

        override fun onResourceReady(
            resource: Drawable?,
            model: Any?,
            target: Target<Drawable>?,
            dataSource: DataSource?,
            isFirstResource: Boolean
        ): Boolean {
            onComplete()
            return false
        }

        override fun onLoadFailed(
            e: GlideException?,
            model: Any?,
            target: Target<Drawable>?,
            isFirstResource: Boolean
        ): Boolean {
            onComplete()
            return false
        }
    }
}

and that is it!

1. In xml take progress bar with height & width(match_parent).

2. Before call below mention method , set progress bar visibility Visible.

   public void setImageWIthProgressBar(Context context, final ImageView imageView, String imageUrl, final ProgressBar progressBar) {
   
           Glide.with(context)
                   .load(imageUrl)
                   .listener(new RequestListener<String, GlideDrawable>() {
                       @Override
                       public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
                           progressBar.setVisibility(View.GONE);
                           return false;
                       }
   
                       @Override
                       public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
                           progressBar.setVisibility(View.GONE);
                           return false;
                       }
                   })
                   .into(imageView);
   
       }//setImageWIthProgressBar
   

Answer 4

Question is rather old, and I don't know what was the situation with glide in those times, but now it can be easily done with listener (not as proposed in the answer chosen as correct).

progressBar.setVisibility(View.VISIBLE);
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) {
             progressBar.setVisibility(View.GONE);
             return false;
         }
     })
     .into(imageFrame)
;

You return true if want to handle things like animations yourself and false if want glide to handle them for you.

Answer 5

GlideDrawable are deprecated, use simple Drawable

RequestOptions requestOptions = new RequestOptions();
requestOptions.placeholder(R.drawable.placeholder);
requestOptions.error(R.drawable.error);

Glide.with(getContext())
                 .setDefaultRequestOptions(requestOptions)
                 .load(finalPathOrUrl)
                 .listener(new RequestListener<Drawable>() {
                        @Override
                        public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                            progressBar.setVisibility(View.GONE);
                            return false;
                        }

                        @Override
                        public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                            progressBar.setVisibility(View.GONE);
                            return false;
                        }
                    })
                 .into(mImageView);

Answer 6

The above solution works pretty well for me too but when i use asBitmap() to download the image. It does not work.

We need to use BitmapImageViewTarget

Glide.with(this) .load(imageURL)
 .asBitmap()
 .placeholder(R.drawable.bg)
 .into(new BitmapImageViewTarget(imageView) {
            @Override
            public void onResourceReady(Bitmap  drawable, GlideAnimation anim) {
                super.onResourceReady(drawable, anim);
                progressBar.setVisibility(View.GONE);
            }
        });
