u can use % operator. It returns remainder of a division. For example, if you have 6 views and 4 images, you can do this way:

ImageView[] viewsArray = new ImageView[6];
//init your array with findViewById()

for(int i = 0; i < viewsArray.length; ++i) {
   viewsArray[i].setImageDrawable(imagesArray[i % 4]); // if your index is 5 % operator will return 1.  
}
