我想在OnReceive动作上播放一首歌，但事实并非如此

Question

+我的SetAction值在OnReceive方法上成功比较，但我想在该动作上播放一首歌，但我无法帮助我 +我的BroadcastReceiver类正在关注

package com.Audio.audioplayer;

import android.appwidget.AppWidgetManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat.Builder;
import android.util.Log;
import android.view.View;
import android.widget.ImageButton;
import android.widget.Toast;

public class MyReceiver extends BroadcastReceiver implements  Listenercalling{
    Listenercalling ls;
    private static final String TAG = "waaaawoooooooooOOOOOOjnjkhdfku";
    public void onReceive(Context context, Intent intent) {
        //btnplay=(ImageButton)btnplay;
         final String action=intent.getAction();
         if(action.equals("btnplay"))
         { 

             ls=new PlayerAudioActivity();

         }
        // if(AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)){
        Log.d(TAG, ""+action);
//           Bundle extras=intent.getExtras();
//           String ieString=extras.getString("Locale");
    //       try{
//               final int Appwidgid=extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID,AppWidgetManager.INVALID_APPWIDGET_ID);
//               if(Appwidgid!=AppWidgetManager.INVALID_APPWIDGET_ID)
//               {
//                   this.onDeleted(context, new int[] { Appwidgid });
//               }
//            else {
//                onReceive(context, intent);
//                 }
//              context.startService(new Intent(context,PlayerAudioActivity.class));
//              Log.i(TAG,"Starting Service ConnectivityListener");
//          }catch(Exception e){
//              Log.e(TAG,e.toString());
//          }
//       }
    }

    private void onDeleted(Context context, int[] is) {
        // TODO Auto-generated method stub

    }

}

My Notifiaction方法遵循以下功能AudiopllayerActivity

private void Notify(String notificationTitle, String notificationMessage) 
    {
        String ns=Context.NOTIFICATION_SERVICE;
        NotificationManager notificationManager=(NotificationManager)getSystemService(ns);
        @SuppressWarnings("deprecation")
        Notification notification=new Notification(R.drawable.bg,"Time",System.currentTimeMillis());
        RemoteViews notificationView=new RemoteViews(getPackageName(),R.layout.main);
        Intent notificationIntent=new Intent(this,PlayerAudioActivity.class);
        PendingIntent pendingNotificationIntent=PendingIntent.getActivity(this, 0, notificationIntent, 0);

        notification.contentView=notificationView;
        notification.flags|=Notification.FLAG_NO_CLEAR;
        //supposed button call intent
        Intent switchIntent=new Intent(this,MyReceiver.class);
        switchIntent.setAction("btnplay");
        PendingIntent pendingIntent=PendingIntent.getBroadcast(this, 0, switchIntent, 0);
        notificationView.setOnClickPendingIntent(R.id.btnPrevious, pendingIntent);
//      Builder mBuilder = new NotificationCompat.Builder(this);
//      
//      mBuilder
//        .setContentTitle(notificationTitle )
//        .setContentText(notificationMessage)
//        .setSmallIcon(R.drawable.btn_play)
//        .setContentIntent(pendingIntent)
//        .addAction(R.drawable.btn_previous,"", pendingIntent)
//        .addAction(R.drawable.btn_pause,"", pendingIntent)
//        .addAction(R.drawable.btn_next,"", pendingIntent).build();
//         btnprevious.setOnClickListener(new View.OnClickListener() {
//          
//          @Override
//          public void onClick(View v) {
//              if(currentSongIndex>0)
//              {
//                  playSong(currentSongIndex-1);
//                  currentSongIndex=currentSongIndex-1;
//              }
//              else
//              {
//                  playSong(songsList.size());
//                  currentSongIndex=(songsList.size()-1);
//              }
//              
//          }
//      });
//      
        notificationManager.notify(1, notification);
    }
