当应用程序关闭时，AlarmManager 调用的通知活动不会弹出答案

【问题描述】：

对于自定义提醒应用，我使用AlarmManager 和PendingIntent 设置弹出Notification 的特定时间。

我在ReceiverActivity 中有我的NotificationManager

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_alarm_receiver);
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager mNotificationManager = (NotificationManager)
            getSystemService(ns);
    Context context = getApplicationContext();
    CharSequence ticker = "You have notification";
    CharSequence contentTitle = "My Reminder";
    CharSequence contentText = "Reminder Content";
    Notification notification = new Notification(R.drawable.notif_icon,
            ticker, System.currentTimeMillis());
    Intent notificationIntent = new Intent(this,
            AlarmReceiverActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
        notificationIntent, 0);
    notification.setLatestEventInfo(context, contentTitle, contentText,
        contentIntent);
    final int HELLO_ID = 1;
    mNotificationManager.notify(HELLO_ID, notification);
}

ReceiverActivity在指定时间弹出，加上通知栏（左上角）的通知，一切正常。但它不是那么用户友好，我只希望通知出现在通知栏中，而不会在应用关闭时弹出任何活动（在实际情况下，可能在您的提醒到期时关闭）

【问题讨论】：

实际上我需要做的就是将 ReceiverActivity 设置为透明，这可以通过更改 xml 中的主题来实现，但我还没有一个可行的解决方案
请发布更多代码，我感觉你在 AlarmManager 调用中启动了错误的东西，但如果没有看到代码就无法判断。

【解决方案1】：

定义您的AlarmManager 的PendingIntent 以由BroadcastReceiver 接收

Intent i = new Intent(context, YourReceiver.class);
PendingIntent alarmPendingIntent= PendingIntent.getBroadcast(context, 0, i,
            PendingIntent.FLAG_UPDATE_CURRENT);

然后

public class YourReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // use a BUILDER all this is deprecated
        CharSequence ticker = "You have notification";
        CharSequence contentTitle = "My Reminder";
        CharSequence contentText = "Reminder Content";
        Notification notification = new Notification(R.drawable.notif_icon,
                ticker, System.currentTimeMillis());
        Intent notificationIntent = new Intent(this,
                AlarmReceiverActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);
        notification.setLatestEventInfo(context, contentTitle, contentText,
            contentIntent);
        // post notification
        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager)
                context.getSystemService(ns);
        final int HELLO_ID = 1;
        mNotificationManager.notify(HELLO_ID, notification);
    }
}
