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);

使用LocalBroadcastManager的Kotlin版本:

请检查下面的注册代码， 发送和接收广播消息。

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // register broadcast manager
        val localBroadcastManager = LocalBroadcastManager.getInstance(this)
        localBroadcastManager.registerReceiver(receiver, IntentFilter("your_action"))
    }

    // broadcast receiver
    var receiver: BroadcastReceiver = object : BroadcastReceiver() {
        override fun onReceive(context: Context?, intent: Intent?) {
            if (intent != null) {
                val str = intent.getStringExtra("key")
                
            }
        }
    }

    /**
     * Send broadcast method
     */
    fun sendBroadcast() {
        val intent = Intent("your_action")
        intent.putExtra("key", "Your data")
        LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
    }

    override fun onDestroy() {
        // Unregister broadcast
        LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver)
        super.onDestroy()
    }

}

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。

我更愿意全面地回答。

LocalbroadcastManager included in android 3.0 and above so you have to use support library v4 for early releases. see instructions here Create a broadcast receiver: private BroadcastReceiver onNotice= new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // intent can contain anydata Log.d("sohail","onReceive called"); tv.setText("Broadcast received !"); } }; Register your receiver in onResume of activity like: protected void onResume() { super.onResume(); IntentFilter iff= new IntentFilter(MyIntentService.ACTION); LocalBroadcastManager.getInstance(this).registerReceiver(onNotice, iff); } //MyIntentService.ACTION is just a public static string defined in MyIntentService. unRegister receiver in onPause: protected void onPause() { super.onPause(); LocalBroadcastManager.getInstance(this).unregisterReceiver(onNotice); } Now whenever a localbroadcast is sent from applications' activity or service, onReceive of onNotice will be called :).

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);
