Question

我正在尝试在我的应用进行每日检查时通知用户。代码运行正常但通知从未出现在状态栏中。谁能明白为什么？

public class OnNotificationReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    WakeReminderIntentService.acquireStaticLock(context);
    Intent i = new Intent(context, NotificationService.class);
    context.startService(i);

    Bundle extra = intent.getExtras();
    int icon = extra.getInt("icon");
    notification(context, icon);

    Log.d("DailyCheck", "Checking for sales");
}
 private void notification(Context ctx, int icon) {
        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) ctx.getSystemService(ns);


        CharSequence tickerText = "ticker";
        long when = System.currentTimeMillis() + 1000;


        Notification notification = new Notification(icon, tickerText, when);


        CharSequence contentTitle = "Title Here";
        CharSequence contentText = "Text here";
        Intent notificationIntent = new Intent(ctx, MainActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, notificationIntent, 0);

        notification.setLatestEventInfo(ctx, contentTitle, contentText, contentIntent);
        notification.flags |= Notification.DEFAULT_SOUND;

        mNotificationManager.notify(9999, notification);
    }

}

编辑：我尝试将其复制到我的主线程（通知方法），它工作正常。那么它必须是BroadcastReceiver的东西吗？

编辑2：传递给它的上下文是MainActivity.this（我的主要活动）

Answer 1

在通知顶部尝试此行，然后将此上下文用于方法的其余部分：

Context context = ctx.getApplicationContext();

通知无法从Android广播接收器工作
