本文提供了Android中发送和接收广播的具体代码示例。发送方通过Intent传递数据，接收方解析并处理这些数据来更新UI。文章展示了如何使用广播进行组件间通信。

1. 发送广播的代码

Intent intent1 = new Intent();
     intent1.setAction("com.mshop");
     double sum = countSum();
     String mzhekouPrices= zhekouPrice();
     intent1.putExtra("sum", sum);
     intent1.putExtra("mzhekouPrice", mzhekouPrices.replace("null", ""));
     mContext.sendBroadcast(intent1);

2. 接收广播的代码

class MyReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
   // TODO Auto-generated method stub

   zhekouPriceSum = intent.getDoubleExtra("sum", 0);
   mzhekouPrices = intent.getStringExtra("mzhekouPrice");
   Double price = Double.parseDouble(splash_win.order_price);
   Double cuxiaoPrice = Double.parseDouble(splash_win.cuxiao);
   Double mpostFee = Double.parseDouble(splash_win.postFee);
   TextView acturl_price = (TextView) findViewById(R.id.payment);
   double sum = zhekouPriceSum + price + mpostFee - cuxiaoPrice;
   acturl_price.setText(sum+"");
  }
