在通知中将 Activity 作为参数传递

Question

我将通知定义为：

   private void sendNotification(String msg, Activity onClickActivity) {

        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);

        // Send to the login activity, since if already a member and logged in, should be able to start that activity

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, onClickActivity), 0);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.gcm_cloud)
                .setContentTitle("Hello")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

    }

如您所见，我希望能够允许动态引用 PendingIntent，以便用户可以单击通知并随后访问给定 Activity onClickActivity 的不同活动。目前错误说明它无法解析构造函数。

我怎样才能让它工作？

Intent constructor 需要 class，而不是 instance。只需将您的方法签名更改为

private void sendNotification(String msg, Class<? extends Activity> onClickActivity) {
