Android 广播的使用

先创建一个类继承广播，并且定义一个接口传递所需要的参数

public class ADReceiver extends BroadcastReceiver {

    private BRInteraction brInteraction;
    @Override
    public void onReceive(Context context, Intent intent) {
        // 广告发送消息后,这里接受广播(ADSendMsg为发送广播标识)
        if (intent.getAction().equals("ADSendMsg")) {
            String name = intent.getExtras().getString("name");
            brInteraction.app2IsClosedcallBack(name);
        }
    }

    // 自定义接口实现对广告发送消息的处理
    public interface BRInteraction {
        public void app2IsClosedcallBack(String content);
    }

    public void setBRInteractionListener(BRInteraction brInteraction) {
        this.brInteraction = brInteraction;
      }
}

在需要接受广播的类里面注册广播

Tip:这个方法的类里面需要继承广播的接口

private void initBroadcastReciver() {
        IntentFilter mIntentFilter = new IntentFilter();
        mIntentFilter .addAction("ADSendMsg");
        myReceiver = new ADReceiver();
        // 注册此监听
        myReceiver.setBRInteractionListener(this);
        registerReceiver(myReceiver, mIntentFilter);
    }

在需要发送广播的地方

// 发送广播
private void sendBroadcastReciver() {
    Intent intent = new Intent("ADSendMsg");
    intent.putExtra("key", value);
    sendBroadcast(intent);
  }
