Android Glide placeholder size

Question

I have a problem with Android Glide. I am trying to quickly swap my image, they just become all placeholder size, and my placeholder image is very low size. So what I need t

Answer 1

I do it like mentioned below:

The idea is to set the scale type to as required by the place holder initially & attach listener to change the scale type again to as required by the downloaded image after the image is downloaded.

//ivBuilderLogo = Target ImageView
//Set the scale type to as required by your place holder
//ScaleType.CENTER_INSIDE will maintain aspect ration and fit the placeholder inside the image view
holder.ivBuilderLogo.setScaleType(ImageView.ScaleType.CENTER_INSIDE); 

//AnimationDrawable is required when you are using transition drawables
//You can directly send resource id to glide if your placeholder is static
//However if you are using GIFs, it is better to create a transition drawable in xml 
//& use it as shown in this example
AnimationDrawable animationDrawable;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
     animationDrawable=(AnimationDrawable)context.getDrawable(R.drawable.anim_image_placeholder);
else
     animationDrawable=(AnimationDrawable)context.getResources().getDrawable(R.drawable.anim_image_placeholder);
animationDrawable.start();

Glide.with(context).load(logo_url)
                   .placeholder(animationDrawable)
                   .listener(new RequestListener() {
                        @Override
                        public boolean onException(Exception e, String model, Target target, boolean isFirstResource)
                        {
                           return false;
                        }

                        //This is invoked when your image is downloaded and is ready 
                        //to be loaded to the image view
                        @Override
                        public boolean onResourceReady(GlideDrawable resource, String model, Target target, boolean isFromMemoryCache, boolean isFirstResource)
                        {   
                        //This is used to remove the placeholder image from your ImageView 
                        //and load the downloaded image with desired scale-type(FIT_XY in this case)
                        //Changing the scale type from 'CENTER_INSIDE' to 'FIT_XY' 
                        //will stretch the placeholder for a (very) short duration,
                        //till the downloaded image is loaded
                        //setImageResource(0) removes the placeholder from the image-view 
                        //before setting the scale type to FIT_XY and ensures that the UX 
                        //is not spoiled, even for a (very) short duration
                            holder.ivBuilderLogo.setImageResource(0);
                            holder.ivBuilderLogo.setScaleType(ImageView.ScaleType.FIT_XY);
                            return false;
                        }
                    })
                    .into( holder.ivBuilderLogo);

My transition drawable (R.drawable.anim_image_placeholder) :
