Set Background Image to Relative Layout using Glide in Android

Question

How can I do this using Glide? I want to cache image to use it another time also. Thanks in advance.

Answer 1

Glide.with(ctx).asBitmap().load(url).centerCrop().into(object: CustomTarget(){
            override fun onLoadCleared(placeholder: Drawable?) {
            }

            override fun onResourceReady(resource: Bitmap, transition: Transition?) {
                val wRatio = view.width/resource.width.toFloat()
                val hRatio = view.height / resource.height.toFloat()

                val minRatio = min(wRatio,hRatio)

                val destBitmap = Bitmap.createScaledBitmap( resource,(resource.width*minRatio).toInt(), (resource.height*minRatio).toInt(),false)
               view.background = BitmapDrawable(resources,destBitmap)
            }
        })

This works for me

PS: There would be an error when the bitmap is too large

java.lang.RuntimeException: Canvas: trying to draw too large bitmap.

So you'd better scale that bitmap like what i did in above code
