How to convert a bitmap to an image resource - Android

Question

I am trying to set an image to a custom View, but my problem is that this custom view only accept the setImageResource() method.

My image files are stored locally inside the phone, so I use a code to encode them to bitmap.

Can I use the setImageResource() function to display bitmap images in some way?

Answer 1

No, sorry. The custom view would need to be modified to support other image sources.

Answer 2

For the custom view you need to modify the support, once you have do it, then If it is encoded on Base64, you can transform that content to a image

val decodedString = Base64.decode(document.thumbnailImage, Base64.DEFAULT)
val decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.size)
imageView.setImageBitmap(decodedByte)
