java一个应用程序中的两个并行通知（安卓）

Question

我想编写一个应用程序，发送两种类型的通知。用户应该同时看到它们

到目前为止，即使我更改了PendingEvents的标志，通知也会相互更新

这是我的代码：

Calendar calendar = Calendar.getInstance();

Intent intent = new Intent(this, Push.class);
Intent intent2 = new Intent(this, Push2.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent pendingIntent2 = PendingIntent.getBroadcast(this, 1, intent2, PendingIntent.FLAG_UPDATE_CURRENT);

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
AlarmManager alarmManager2 = (AlarmManager) getSystemService(ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis()+10, pendingIntent);
alarmManager2.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis()+10, pendingIntent2);

Answer 1

创建两个不同的通知生成器对象

范例

第一个通知对象

Notification.Builder builder = new Notification.Builder(context);

builder.setContentIntent(contentIntent)
            .setSmallIcon(R.drawable.some_img)
            .setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.some_big_img))            
            .setAutoCancel(true)
            .setContentTitle(res.getString(R.string.your_notif_title))
            .setContentText(res.getString(R.string.your_notif_text));
Notification n1 = builder.build();

第二个通知对象

Notification.Builder builder2 = new Notification.Builder(context);

builder.setContentIntent(contentIntent)
            .setSmallIcon(R.drawable.some_img)
            .setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.some_big_img))            
            .setAutoCancel(true)
            .setContentTitle(res.getString(R.string.your_notif_title))
            .setContentText(res.getString(R.string.your_notif_text));
Notification n2 = builder2.build();

NotificationManager nm = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);

使用通知管理器显示通知

nm.notify(YOUR_NOTIF_ID, n1);
nm.notify(YOUR_NOTIF_ID_2, n2);
