Question

在回收者视图中单击一个单元时，我试图将数据发送到广播接收者。因此它可以启动计时器并在计时器中输入正确的数据后显示通知。

但是，当我将数据发送到广播接收器时，在触发通知时我会收到不正确的数据。

这是我的Adapter类中的代码，它将数据发送到public void onBindViewHolder(MyViewHolder holder, final int position)方法中的Boradcast Reciever中

                @Override
                public void onClick(View view) {
                    int ONE_SECOND = 1000;
                    Intent intent = new Intent(context, BroadcastReminder.class);
                    Bundle bundle = new Bundle();
                    bundle.putString("name", timer.getTimer_name());
                    bundle.putString("img", timer.getTimer_img());
                    intent.putExtra("bundle", bundle);
                    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
                    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

                    long timeAtStart = System.currentTimeMillis();
                    long duration_s = ONE_SECOND * 10;

                    alarmManager.set(AlarmManager.RTC_WAKEUP,
                            timeAtStart + duration_s, pendingIntent);
                }
            });

然后将启动服务，并在触发通知时，广播接收者将从意图包中接收数据并显示通知。（但是，接收到错误的数据，每次总是在项目中使用相同的元素）

public class BroadcastReminder extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

        Bundle bundle = intent.getBundleExtra("bundle");
        String timer_name = bundle.getString("name");
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "notifyLemubit")
                .setSmallIcon(icon)
                .setContentTitle("Timer Finished")
                .setContentText("Your " + timer_name + " Tree is Ready!")
                .setPriority(NotificationCompat.PRIORITY_DEFAULT);

        NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(context);
        notificationManagerCompat.notify(200, builder.build());

    }
}

感谢您的帮助。谢谢

问题在于待处理的意图标志为0。应该在FLAG_UPDATE_CURRENT每次运行时更新值的时间。

将数据从Recycler View适配器发送到BroadcastReciever
