EventBus与适配器

EventBus导入依赖：compile 'org.greenrobot:eventbus:3.0.0'

//注册EventBus

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {    view = inflater.inflate(R.layout.fragment_shopping, null);    //注册EventBus    EventBus.getDefault().register(this);    initView();    return view;}
//订阅方法，当接收到事件的时候，会调用该方法//获取价格@Subscribe(threadMode = ThreadMode.MAIN)public void onEvent(MoneyAndCount moneyAndCount) {    //double类型保留2位小数点    DecimalFormat df = new DecimalFormat("######0.00");    contprice.setText("总价:" + df.format(moneyAndCount.getPrice()));    jiesuan.setText("结算(" + moneyAndCount.getCount() + ")");}

//解除注册

@Overridepublic void onDestroy() {    super.onDestroy();    //解除注册    EventBus.getDefault().unregister(this);}
