接收端:

First register LocalBroadcast Receiver Then handle incoming intent data in onReceive. @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LocalBroadcastManager lbm = LocalBroadcastManager.getInstance(this); lbm.registerReceiver(receiver, new IntentFilter("filter_string")); } public BroadcastReceiver receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (intent != null) { String str = intent.getStringExtra("key"); // get all your data from intent and do what you want } } };

发送端:

   Intent intent = new Intent("filter_string");
   intent.putExtra("key", "My Data");
   // put your all data using put extra 

   LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

在Eclipse中，最终我不得不通过右键单击我的项目并选择添加兼容性/支持库:

Android工具->添加支持库

一旦添加了它，我就可以在代码中使用LocalBroadcastManager类了。

我还是要回答这个问题。以防有人需要。

ReceiverActivity.java

一个监视名为“custom-event-name”的事件通知的活动。

@Override
public void onCreate(Bundle savedInstanceState) {

  ...

  // Register to receive messages.
  // We are registering an observer (mMessageReceiver) to receive Intents
  // with actions named "custom-event-name".
  LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
      new IntentFilter("custom-event-name"));
}

// Our handler for received Intents. This will be called whenever an Intent
// with an action named "custom-event-name" is broadcasted.
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
    // Get extra data included in the Intent
    String message = intent.getStringExtra("message");
    Log.d("receiver", "Got message: " + message);
  }
};

@Override
protected void onDestroy() {
  // Unregister since the activity is about to be closed.
  LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
  super.onDestroy();
}

SenderActivity.java

第二个活动发送/广播通知。

@Override
public void onCreate(Bundle savedInstanceState) {

  ...

  // Every time a button is clicked, we want to broadcast a notification.
  findViewById(R.id.button_send).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
      sendMessage();
    }
  });
}

// Send an Intent with an action named "custom-event-name". The Intent sent should 
// be received by the ReceiverActivity.
private void sendMessage() {
  Log.d("sender", "Broadcasting message");
  Intent intent = new Intent("custom-event-name");
  // You can also include some extra data.
  intent.putExtra("message", "This is my message!");
  LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
}

使用上面的代码，每次按钮都是R.id。button_send被点击，Intent被广播并被ReceiverActivity中的mMessageReceiver接收。

调试输出应该是这样的:

01-16 10:35:42.413: D/sender(356): Broadcasting message
01-16 10:35:42.421: D/receiver(356): Got message: This is my message! 

我们也可以使用接口相同的broadcastManger在这里我分享broadcastManager的测试代码，但通过接口。

首先，创建如下界面:

public interface MyInterface {
     void GetName(String name);
}

2-这是第一个需要实现的类

public class First implements MyInterface{

    MyInterface interfc;    
    public static void main(String[] args) {
      First f=new First();      
      Second s=new Second();
      f.initIterface(s);
      f.GetName("Paddy");
  }
  private void initIterface(MyInterface interfc){
    this.interfc=interfc;
  }
  public void GetName(String name) {
    System.out.println("first "+name);
    interfc.GetName(name);  
  }
}

3-这里是实现相同接口的第二个类，其方法自动调用

public class Second implements MyInterface{
   public void GetName(String name) {
     System.out.println("Second"+name);
   }
}

因此，通过这种方法，我们可以使用与broadcastManager功能相同的接口。

接收端:

First register LocalBroadcast Receiver Then handle incoming intent data in onReceive. @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LocalBroadcastManager lbm = LocalBroadcastManager.getInstance(this); lbm.registerReceiver(receiver, new IntentFilter("filter_string")); } public BroadcastReceiver receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (intent != null) { String str = intent.getStringExtra("key"); // get all your data from intent and do what you want } } };

发送端:

   Intent intent = new Intent("filter_string");
   intent.putExtra("key", "My Data");
   // put your all data using put extra 

   LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

如何将全局广播更改为局部广播

1)创建实例

LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);

2)用于注册BroadcastReceiver

取代

registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

与

localBroadcastManager.registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

3)用于发送广播信息

取代

sendBroadcast(intent);

与

localBroadcastManager.sendBroadcast(intent);

4)注销广播信息

取代

unregisterReceiver(mybroadcast);

与

localBroadcastManager.unregisterReceiver(mybroadcast);
