我似乎找不到这个问题的答案，一直到处搜寻。
我正在尝试在我的项目中管理两个单独的通知。我有一个通知，在帐单到期时会发送给用户，而在付款成功时会发送给用户。
当我从AlarmReceiver类调用通知时，即使是账单到期通知，也会调用付款通知。我认为这是因为它在OnReceive中被称为最后一个，因此这取消了该账单的到期通知。
我可以在OnReceive中放入某种if或switch语句，以查看已调用了哪个请求代码（101或102），然后调用该通知吗？
这是我的代码：
public class AlarmReceiver extends BroadcastReceiver {
private static final String CHANNEL_ID = "bills.channelId";
/**
* @param context
* @param intent
*/
@Override
public void onReceive(Context context, Intent intent) {
// run notification 1
userHasBill(context, intent);
// run notification 2
userPaymentIsSuccessful(context, intent);
}
/**
* Notification to call when the user sets a reminder
* @param intent
*/
public void userHasBill(Context context, Intent intent) {
Intent notificationIntent = new Intent(context, MainMenuActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(EmailActivity.class);
stackBuilder.addNextIntent(notificationIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(101, PendingIntent.FLAG_UPDATE_CURRENT);
Notification.Builder builder = new Notification.Builder(context);
// Notification Builder and setting parameters?
Notification notification = builder.setContentTitle("Bill Reminder!")
.setContentText("Just a reminder that you have a bill due!")
.setTicker("Just a reminder that you have a bill due!")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pendingIntent).build();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId(CHANNEL_ID);
}
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(
CHANNEL_ID,
"bills",
IMPORTANCE_DEFAULT
);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(1, notification);
}
/**
* Notification to call when bill payment is successful
*
* @param context current context
* @param intent intent to go to home activity
*/
public void userPaymentIsSuccessful(Context context, Intent intent) {
Intent notificationIntent = new Intent(context, MainMenuActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(EmailActivity.class);
stackBuilder.addNextIntent(notificationIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(102, PendingIntent.FLAG_UPDATE_CURRENT);
Notification.Builder builder = new Notification.Builder(context);
Notification notification = builder.setContentTitle("Payment successful!")
.setContentText("Your payment was successful!")
.setTicker("Your Payment was Successful!")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pendingIntent).build();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId(CHANNEL_ID);
}
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(
CHANNEL_ID,
"bills",
IMPORTANCE_DEFAULT
);
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(1, notification);
}
}
我已经尝试制作两个频道ID，但是它仍然调用OnReceive中的第二个通知
最佳答案
您需要使用唯一的通知ID。当前，您为两个通知使用相同的ID：
notificationManager.notify(1, notification);
另请参阅通知指南中的"Show the notification"
我可以在OnReceive中放入某种if或switch语句，以查看已调用了哪个请求代码（101或102），然后调用该通知吗？
AlarmReceiver由其他组件触发。该组件可以为广播使用的Intent附加一些标志。然后，您可以在Intent中评估onReceive()附加项目
