Expandable custom notification Handle event by using BroadcastReceiver

I am writing code for handling action event from notification by using BroadcastReceiver and also you can handle by using other way with in same activity.

MainActivity.java

package com.example.addactionnotification;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.view.View.OnClickListener;

public class MainActivity extends ActionBarActivity implements OnClickListener {
 static String CLOSE_ACTION = "close_action";
 static String ACCEPT_ACTION = "accept_action";
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
 }

 @Override
 public void onClick(View view) {

  switch (view.getId()) {
  case R.id.btnAdddActionNotification:

   showAddActionNotification();
   break;
  default:
   break;
  }
 }

 private void showAddActionNotification() {

  int icon = R.drawable.ic_launcher;

  NotificationCompat.Builder builder = new NotificationCompat.Builder(this);

  builder.setSmallIcon(icon);

  builder.setContentText("Add action notification").setContentTitle("Here is accept and close action only");

  Intent closeIntent = new Intent(this, MyReceiver.class);


  closeIntent.setAction(CLOSE_ACTION);


  PendingIntent closePendingIntent = PendingIntent.getBroadcast(this, 12345, closeIntent, PendingIntent.FLAG_UPDATE_CURRENT);

  builder.addAction(R.drawable.history, "Close", closePendingIntent);

  Intent acceptIntent = new Intent();
  acceptIntent.setAction(ACCEPT_ACTION);

  PendingIntent acceptPendingIINtent = PendingIntent.getBroadcast(this, 12345, acceptIntent, PendingIntent.FLAG_UPDATE_CURRENT);


  builder.addAction(R.drawable.contact, "Accept", acceptPendingIINtent);

  Notification notification = builder.build();


  Intent notificationIntent = new Intent(this, MainActivity.class);

  PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


  notification.contentIntent = contentIntent;

  notification.flags |= Notification.FLAG_NO_CLEAR | Notification.FLAG_SHOW_LIGHTS;
  NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

  mNotificationManager.notify(1, notification);
 }
}

MyReceiver.java

package com.example.addactionnotification;
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) {
  String action = intent.getAction();
  if (MainActivity.CLOSE_ACTION.equals(action)) {

   // write code for close action
   Toast.makeText(context, "Hello close action", Toast.LENGTH_LONG).show();

  } else if (MainActivity.ACCEPT_ACTION.equals(action)) {
   Toast.makeText(context, "Hello close action", Toast.LENGTH_LONG).show();
   // write code for accept action
  }
 }
}

activity_main.xml
