that's all!

Answer 1

try something like this to increase width and height with 5 :

final android.view.ViewGroup.LayoutParams layoutParams = imageView.getLayoutParams();

    buttonIncrease.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            layoutParams.width += 5;
            layoutParams.height += 5;
            imageView.setLayoutParams(layoutParams);
        }
    });

Answer 2

imageView.getLayoutParams().height += 1; (or -) imageView.getLayoutParams().width += 1;
