在Activity中设置监听器

class AuthorityListener implements OnClickListener{        int i;        public AuthorityListener(int i){            this.i=i;        }        @Override        public void onClick(View v) {            PermissionUtils.requestPermission(MainActivity.this,i);        }    }

findViewById(R.id.button_1).setOnClickListener(new AuthorityListener(PermissionUtils.CODE_RECORD_AUDIO));//0
