[DISCUSSION] OnClickListener() usage

Hi guys. When i am writing code, i wondered something

Which OnClickListener type is more CPU and power friendly ?

A: Implementing OnClickListener to the Acitivity.

for example:

Code:

---

cpu_freq_limit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
              //something

            }

        });

---

B: Setting OnClickListener to a object. (like button)

for example:

Code:

---

@Override
    public void onClick(View v) {
        if(v==read) {
        //something
        }
