在不在应用程序上时发送Android通知

当用户单击按钮时，我会收到通知。我希望在用户不点击此按钮且不在应用程序上的情况下发送此通知

实现这一目标的最佳方式是什么

这是我的按钮，正在从广播接收器接收祝酒词：

public void onetimeTimer(View view){
Context context = this.getApplicationContext();
if(alarm != null){
    alarm.setOnetimeTimer(context);
}else{
    Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show();
}

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver {

final public static String ONE_TIME = "onetime";

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
//Acquire the lock
wl.acquire();

//You can do the processing here update the widget/remote views.
Bundle extras = intent.getExtras();
StringBuilder msgStr = new StringBuilder();

if(extras != null && extras.getBoolean(ONE_TIME, Boolean.FALSE)){
 msgStr.append("One time Timer : ");
}
Format formatter = new SimpleDateFormat("hh:mm:ss a");
// msgStr.append(formatter.format(new Date()));

    //msgStr.append();

Toast.makeText(context, msgStr, Toast.LENGTH_LONG).show();

//Release the lock
wl.release();

这是我的Alarm Manager广播接收器：

public void onetimeTimer(View view){
Context context = this.getApplicationContext();
if(alarm != null){
    alarm.setOnetimeTimer(context);
}else{
    Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show();
}

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver {

final public static String ONE_TIME = "onetime";

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
//Acquire the lock
wl.acquire();

//You can do the processing here update the widget/remote views.
Bundle extras = intent.getExtras();
StringBuilder msgStr = new StringBuilder();

if(extras != null && extras.getBoolean(ONE_TIME, Boolean.FALSE)){
 msgStr.append("One time Timer : ");
}
Format formatter = new SimpleDateFormat("hh:mm:ss a");
// msgStr.append(formatter.format(new Date()));

    //msgStr.append();

Toast.makeText(context, msgStr, Toast.LENGTH_LONG).show();

//Release the lock
wl.release();

} 以下是广播接收器中的方法：

public void setOnetimeTimer(Context context){
AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
   Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
   intent.putExtra(ONE_TIME, Boolean.TRUE);
   PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
   am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), pi);
   }

这是一个按钮后面的通知，我希望在不按下按钮的情况下由报警管理器启动

Button btnNotifyWorkout = (Button)findViewById(R.id.btnNotifyWorkout);
        btnNotifyWorkout.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent  = new Intent();
                PendingIntent pIntent = PendingIntent.getActivity(HomeActivity.this, 0, intent, 0);
                Notification noti = new Notification.Builder(HomeActivity.this)
                                            .setTicker("TickerTitle")
                                            .setContentTitle("Lukes App")
                                            .setContentText("You have a workout due today")
                                            .setSmallIcon(R.drawable.ic_launcher)
                                            .setContentIntent(pIntent).getNotification();

                noti.flags = Notification.FLAG_AUTO_CANCEL;
                NotificationManager nm  = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
                nm.notify(0, noti);
            } 
        });

我可能没有正确理解您的问题，但我假设您希望在触发警报时生成通知

您可以将通知移动到BroadcastReceiver的onReceive

您是否在清单中声明了接收人？

你在舱单上声明了接收人吗？

好的，冷静，我该怎么做？好的，冷静，我该怎么做？
