How to user Android-Volley to set animated image until the image loads

In android volley, I know there's an attribute called mDefaultImageId in the NetwrokImageView. But this only displays "Default" still images.

I need to show either an animated image or a progress bar.

I know I can accomplish this if I use RequestQueue, but still I need to take advantages of ImageLoader.

How to accomplish that?

Thanks.

if you are using method to load image then ProgressBar as parameter to that method may help you to hide ProgressBar:

You can try this: https://github.com/vinaysshenoy/enhanced-volley there is Animation added to Volley.

also you can use

NetworkImageView ivImage = (NetworkImageView) rootView.findViewById(R.id.ivImage);
ivImage.setImageUrl(key, mImageLoader);
ivImage.setDefaultImageResId(R.drawable.loading_text);

where for me drawable loading_text was image saying "Loading image..."

You can create your own implementation of the ImageListener class and pass it when requesting the image.

Something along the lines of:

// code for displaying animation / progress wheel

sImageLoader.get(imageUrl, new ImageListener() {

    @Override
    public void onErrorResponse(VolleyError error) {
        // handle errors
    }

    @Override
    public void onResponse(ImageContainer response, boolean isImmediate) {
        if (response.getBitmap() != null) {
            // code to switch out placeholder animation 
            // progress wheel with received response
        }
    }
});
