android广播怎么把接受到的消息返回至activity

android广播怎么把接受到的消息返回至activity

1. 发送广播
Intent intent = new Intent(BroadcastAction);
Bundle bundle = new Bundle();
bundle.putString("***", SUCCESS);
bundle.putString("FullPathName", mFullPathName);
intent.putExtras(bundle);
sendBroadcast(intent);
2.在Activity中创建一个内部类MyBroadcastReceiver扩展BroadcastReceiver，并在其中实现onReceive方法。
 3.在Activity中声明一个MyBroadcastReceiver类型的成员变量，并注册
 private MyBroadcastReceiver myBroadcastReceiver; ... 
myBroadcastReceiver = new MyBroadcastReceiver();
 IntentFilter filter = new IntentFilter(); 
filter.addAction(BroadcastAction); 
registerReceiver(receiver, filter); 
4.使用完后要记得释放 
unregisterReceiver(receiver);

一定会的。
