This type of question was already made, but the answer is quick and I have no problem to give it here:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_VOLUME_UP)){
        // Code
    }
    else if ((keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)){
        // Code
    }
    return true;
}
