Android自定义Notification添加点击事件

public class MyService extends Service {

 public static final String ONCLICK = "com.app.onclick";


 private BroadcastReceiver receiver_onclick = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
   if (intent.getAction().equals(ONCLICK)) {
    Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
    vibrator.vibrate(1000);
   }
  }
 };
 @Override
 public void onCreate() {
  super.onCreate();
  Notification notification = new Notification(R.drawable.ic_launcher,
    "JcMan", System.currentTimeMillis());
  RemoteViews view = new RemoteViews(getPackageName(),R.layout.notification);
  notification.contentView = view;
  IntentFilter filter_click = new IntentFilter();
  filter_click.addAction(ONCLICK);
  //注册广播
  registerReceiver(receiver_onclick, filter_click);
  Intent Intent_pre = new Intent(ONCLICK);
  //得到PendingIntent
  PendingIntent pendIntent_click = PendingIntent.getBroadcast(this, 0, Intent_pre, 0);
  //设置监听
  notification.contentView.setOnClickPendingIntent(R.id.btn,pendIntent_click);
  //前台运行
  startForeground(1, notification);
 }
 @Override
 public IBinder onBind(Intent intent) {
  return null;
 }
}
