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; }}
