Question

我有一个每日警报，其中应包含我只能从活动上下文中获取的文本 - 该活动会根据用户的设置生成一个密钥，以获取特定日期的特定生成信息。

即使应用程序未运行，通知也会在每天上午10点从BootReceiver和AlarmManager启动。

如何将BroadcastReceiver上下文转换为活动，或者为了使用其方法而无形地运行活动？

这就是我设置闹钟的方法：

PendingIntent pendingIntent = PendingIntent.getBroadcast(context, requestCode, intent, 0);
        AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime, AlarmManager.INTERVAL_DAY, pendingIntent);

这是BroadcastReceiver：

public class PushNotificationReceiver extends BroadcastReceiver {

private Context context;


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

    this.context = context;

    String notificationTitle = intent.getExtras().getString("notificationTitle");
    String notificationText;
    boolean dailyNotification = intent.getExtras().getBoolean("dailyNotification ", false);
    int requestCode = intent.getExtras().getInt("requestCode");

    if(dailyNotification ) {

        Log.d("DAILY","DAILY");

        // HERE IS WHERE I NEED A BUNCH OF METHODS FROM THE ACTIVITY TO GENERATE THE TITLE AND THE TEXT FOR THE NOTIFICATION
        notificationTitle = "ASD";
        notificationText = "asd";
    } else {
         notificationText = intent.getExtras().getString("notificationText");
    }

    String soundResource = "android.resource://com.asdqwe.asd/raw/tone";
    Uri soundUri = Uri.parse(soundResource);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context).setContentTitle(notificationTitle)//
            .setContentText(notificationText)//
            .setSmallIcon(R.drawable.app_icon)//
            .setSound(soundUri)//
            .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.app_icon));//

    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(context, MyActivity.class);

    // The stack builder object will contain an artificial back stack for the
    // started Activity.
    // This ensures that navigating backward from the Activity leads out of
    // your application to the Home screen.
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(MyActivity.class);
    // Adds the Intent that starts the Activity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.setContentIntent(resultPendingIntent);
    NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    // mId allows you to update the notification later on.
    mNotificationManager.notify(543, mBuilder.build());


} // End of onReceive
