First of let s your image name is myimage  So what you have to do is that go to Drawable and save the image name myimage   Now assume you know only image name and you need to access it  Use below snippet to access it   what you did is correct   ensure you saved image name you are going to use inside coding   public static int getResourceId Context context  String name  String resourceType        return context getResources   getIdentifier toResourceString name   resourceType  context getPackageName        private static String toResourceString String name        return name replace                          replace                          replace                           replace  -                        replace                          replace   amp                        toLowerCase        In addition to it you should ensure that there is no empty spaces and case sensitives

ImageView imageView findViewById R id imageView   if you have image in drawable folder then use imageView setImageResource R drawable imageView   if you have uri and want to display it in imageView then use imageView setImageUri  quot uri quot    if you have bitmap and want to display it in imageView then use imageView setImageBitmap bitmap   note - 1  imageView setImageDrawable   is now deprecated in java 2  If image uri is from firebase or from any other online link then use     Picasso get        load  quot uri quot        into imageView    https   github com square picasso  or use Glide with context               load  quot uri quot                into imageView    https   github com bumptech glide
