@Override

        switch (v.getId()) {
            case R.id.rl_back:
                ((Activity) mContext).finish();
                break;

            case R.id.rl_right:
                if (onRightClickListener != null) {
                    onRightClickListener.onRight();
                }
                break;

        }
    }

    public interface OnRightClickListener {
        void onRight();
    }

    private OnRightClickListener onRightClickListener;


    public void setOnRightClickListener(OnRightClickListener onRightClickListener) {
        this.onRightClickListener = onRightClickListener;
    }
}

布局文件中使用
