MainActivity代码

package com.example.luobo.mybroadcastreceiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.support.v4.content.LocalBroadcastManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

  private Button button;
  private IntentFilter intentFilter;
  private LocalBroadcastManager localBroadcastManager ;
  private LocalReceiver localReciiver;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    button = (Button)findViewById(R.id.send_button);
    button.setOnClickListener(this);
    localBroadcastManager = LocalBroadcastManager.getInstance(this);//使用
    intentFilter = new IntentFilter();
    intentFilter.addAction("com.example.luobo.mybroadcastreceiver.LOCAL_BROADCAST");
    localReciiver = new LocalReceiver();
    localBroadcastManager.registerReceiver(localReciiver,intentFilter);
  }

  @Override
  protected void onDestroy() {
    super.onDestroy();
    localBroadcastManager.unregisterReceiver(localReciiver);
  }

  @Override
  public void onClick(View view) {
    Intent intent = new Intent("com.example.luobo.mybroadcastreceiver.LOCAL_BROADCAST");
    localBroadcastManager.sendBroadcast(intent);
  }
  class LocalReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
      Toast.makeText(context,"received local broadcast",Toast.LENGTH_SHORT).show();
    }
  }
}

首先通过LocalBroadcastManager（本地广播管理类）的getInstance(this)方法获取实例，注册广播消息时是调用localBroadcastManager实例的registerReceiver(参数1,参数2)方法注册（参数1是本地广播接受者，参数2是过滤器只选择接收特定的广播消息），调用localBroadcastManager实例的sendBroadcast（Initent initent）方法发送广播消息。

MyRecevity

package com.example.luobo.mybroadcastreceiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class MyReceiver extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
    Toast.makeText(context,"Received in MyBroadCastReceiver",Toast.LENGTH_SHORT).show();
    abortBroadcast();
  }
}
