Answer 1

You can use anonymous inner classes to write an onClick function for each button.

Button button1 = getMyButton();
button1.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
      // button 1 was clicked!
   }
  });
Button button2 = getMyButton();
button2.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
      // button 2 was clicked!
   }
  });

As Konstantin mentioned, you can also use the passed in View and switch on the id. However, I find that a bit messier if you end up with lots of clickable things.
