Answer 1

Most ellegant pattern to follow:

public void onClick(View v) { switch(v.getId()) { case R.id.button_a_id: // handle button A click; break; case R.id.button_b_id: // handle button B click; break; default: throw new RuntimeException("Unknow button ID"); } 

This way it's much simplier to debug it and makes sure you don't miss to handle any click.

Answer 2

I have 10 buttons performing the same method updateText(), I used this code to get the clicked button's text:

public void updateText(View v){     Button btn = (Button) findViewById(v.getId());     String text = btn.getText().toString(); }
