How do I create an ImageView in java code, within an existing Layout?

Question

I\'m looking for an easy way for the user to see how many drinks they\'ve had for a BAC calculator.

In the button's click callback, create an ImageView object, set the bottle image, and position it. For example (I'm assuming the names of your elements):

ImageView imageView = new ImageView(this);
imageView.setImageResource(R.drawable.beerbottle);

RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.RelativeLayout01);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WRAP_CONTENT,
    RelativeLayout.LayoutParams.WRAP_CONTENT
);
layoutParams.addRule(RelativeLayout.BELOW, R.id.ButtonRecalculate);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

relativeLayout.addView(imageView, layoutParams);

I haven't tested this, mind you, but it should give you a good start. You'll probably need to add other parameters to the ImageView and possibly to the LayoutParams to make it look good, plus tracking how many bottles are displayed, etc.
