BroadcastReceiverHelper 类：

package com.scd.broadcastreceiver.helper;

import com.scd.broadcastreceiver.activity.MainActivity;

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

  }

  @Override

    if (intent.getAction().equals(MainActivity.ACTION_SENDMESSAGE)) {
      toast("发送成功");
    } else if (intent.getAction()
        .equals(MainActivity.ACTION_DELIVERMESSAGE)) {

  }

  public void toast(String text) {
