ANDROID: Get Button XML Id

I have a 4x4 table from buttons. Their Id like this:

b11 b12 b13 b14
b21 b22 b23 b24
b31 b32 b33 b34
b41 b42 b43 b44

How can I get programmatically the clicked button xml id? For example:

I click to button which has got id:b33
I need the following id-s upper:b23 righter:b32 lefter:b34 under:b43

I can calculate them but I can't get the clicked id :/
I hope you can help me
(Excuse me for the grammar mistakes. I am not a native speaker)
My listener:

public void click(View v){
    Button b = (Button)v;
    String[] string = b.getText().toString().split("|");
    String id = b.getId();
    String[] source = id.split("|");
    Integer y = Integer.parseInt(source[2]);
    Integer x = Integer.parseInt(source[3]);
    Integer uppery = y-1;
    Integer lowery = y+1;
    Integer rightx = x-1;
    Integer leftx = x+1;
    String upperid = uppery.toString()+x.toString();
    String lowerid = lowery.toString()+x.toString();
    String rightid = y.toString()+rightx.toString();
    String leftid = y.toString()+leftx.toString();
}

My xml:

set onClickListener to your Buttons and in your onClick method :

@Override 
public void onClick(View v) {
    int id = v.getId(); // clicked Button id
    switch (id) {
     case R.id.b11:
      ...
      break;
     case R.id.b12:
      ...
      break;
     ...
     default:
      break;
    }
    ...
}
