Answer 1

You can create an ArrayList of Integers and then easily assign the image to the imageview:

Example code:

ArrayList<Integer> list = new ArrayList<Integer>();
list.add(R.drawable.your_image);
imageView.setImageResource(Integer.intValue(list.get(0)));

Answer 2

Within the array will store the names of the pictures, like R.drawable.img1 , R.drawable.img2... Then, use the command:

ImageView img;
img.setImageResource(R.drawable.img1);
