yes its a value of Button , use following code to fetch Text of Button.

Button b = (Button)findViewById(R.id.button1);
String buttonText = b.getText().toString();

function call

b.setOnClickListener(new Button.OnClickListener() {
    @Override
    public void onClick(View v) {
                  // TODO Auto-generated method stub
                  function();
    }
