触发不同的每个通知按钮被点击

Question

我正在创建一个媒体通知，它需要根据单击的按钮触发不同的功能。有什么方法可以区分按钮还是我需要创建 4-5 个单独的 Intent 和 PendingIntent？这是有效的代码，但不完全是应该的：

编辑：我添加了一个新函数来初始化新的挂起意图，但事情是这样的，当我按下播放时，会触发 playIntent，但是当我按下暂停意图时，会再次触发 playIntent。

 private void showNotification(boolean persistent) {
        String channel_id = "TEST_CHANNEL";
        NotificationManager manager = (NotificationManager) getSystemService(
                Context.NOTIFICATION_SERVICE
        );

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            NotificationChannel testChannel = new NotificationChannel(
                    channel_id,
                    "TEST_CHANNEL",
                    NotificationManager.IMPORTANCE_DEFAULT
            );

            testChannel.setLightColor(Color.GREEN);

            assert manager != null;
            manager.createNotificationChannel(testChannel);
        }


        PendingIntent pauseIntent = initIntent("pause");
        PendingIntent playIntent = initIntent("play");

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this, channel_id)
                        .setSmallIcon(R.drawable.ic_remote_control)
                        .addAction(R.drawable.ic_play_button, "Play", playIntent)
                        .addAction(R.drawable.ic_round_pause_button, "Pause", pauseIntent)
                        .addAction(R.drawable.ic_forward, "Title", null)
                        .addAction(R.drawable.ic_back_left_arrow_circular_button, "Title", null)
                        .setStyle(new android.support.v4.media.app.NotificationCompat.MediaStyle())
                        .setOngoing(persistent)
                        .setAutoCancel(true);


        assert manager != null;
        manager.notify(123, mBuilder.build());
    }

    private PendingIntent initIntent(String action) {
        Intent tempIntent = new Intent(this, ActionReceiver.class);

        tempIntent.putExtra("action", action);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

        stackBuilder.addNextIntent(tempIntent);


        return PendingIntent.getBroadcast(
                this,
                1,
                tempIntent,
                PendingIntent.FLAG_UPDATE_CURRENT
        );
    }

您需要为每个操作创建不同的待处理意图。尽管如此，您可以使用同一个类来处理基于每个待处理意图的不同操作的所有操作。
