In my main activity, I've already declared an array of image view objects, that are referencing the die images in the activity layout. I've also created a reference variable that's pointing to this text view object, that's the text at the top of the screen. When the user clicks the floating action button in the lower-right corner, I want to roll the dice using the code in the DiceHelper class. So I'll place this code inside my fabClickHandler function. First I'll create a variable that I'll name dice and I'll get its value by calling DiceHelper.rollDice. So now I have a randomized integer array, now I'm going to loop through the image view objects and set the images one die at a time. I'm going to use an iteration loop that starts with a value of zero and goes until the size of the image view's array…
