Android: how to handle button click

Question

Having a solid experience in non-Java and non-Android area, I\'m learning Android.

I have a lot of confusion with different areas, one of them is how to handle butt

Answer 1

Option 1 and 2 involves using inner class that will make the code kind of clutter. Option 2 is sort of messy because there will be one listener for every button. If you have small number of button, this is okay. For option 4 I think this will be harder to debug as you will have to go back and fourth the xml and java code. I personally use option 3 when I have to handle multiple button clicks.
