我如何将数据从数据库传递到广播接收器并在那里再次接收它们？

Question

我正在尝试开发生日提醒应用程序。我将一些数据存储为姓名、姓氏、生日日期。当用户设置生日日期时，我想将名称变量传递给 BroadcastReciever，这样当警报通知时，我可以显示特定生日的姓名.我怎么能那样做？这是我从 activity 发送数据到 BroadcastReciever:

的一小部分代码

if (dateSelected != null) {
    Intent intent = new Intent(AddBirthday.this, AlarmReceiver.class);
    intent.putExtra("extra", getFirstName);
    sendBroadcast(intent);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(AddBirthday.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    // Set the alarm for a particular time.
    //alarmManager.set(AlarmManager.RTC_WAKEUP, test, PendingIntent.getBroadcast(AddBirthday.this, 1 , intent, PendingIntent.FLAG_UPDATE_CURRENT));
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, test, AlarmManager.INTERVAL_DAY, pendingIntent);
}

这里是 BroadcastReciever:

public class AlarmReceiver extends BroadcastReceiver{

    private int MID;

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

        // TODO Auto-generated method stub
        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        Intent notificationIntent = new Intent(context, MainActivity.class);
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent = PendingIntent.getActivity(context,0,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder mNotifyBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(
                context).setSmallIcon(R.drawable.ic_launcher_icon)
                .setContentTitle("Birthday Upcoming")
                .setContentText("Its " + "birthday" + "Dont Forget To Buy Some Present!").setSound(alarmSound)
                .setAutoCancel(true).setWhen(when)
                .setContentIntent(pendingIntent)
                .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
        notificationManager.notify(MID, mNotifyBuilder.build());
        MID++;
    }
}

我看到了一些关于此的问题，但我不确定我该怎么做。

在你的AndroidManifest.xml中：

<receiver android:name="com.yourapplication.AlarmReceiver">
    <intent-filter>
        <action android:name="com.yourapplication.CUSTOM_INTENT" />
    </intent-filter>
</receiver>

准备在警报响起时触发您的 Intent 时：

Intent intent = new Intent("com.yourapplication.CUSTOM_INTENT");
intent.putExtra("extra", getFirstName);
PendingIntent pendingIntent = PendingIntent.getBroadcast(AddBirthday.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, test, AlarmManager.INTERVAL_DAY, pendingIntent);

名称存储在发送给 AlarmReceiver 的 Intent 中：

@Override
public void onReceive(Context context, Intent intent) {
    String name = intent.getStringExtra("extra");
    ...
    NotificationCompat.Builder mNotifyBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(context).setSmallIcon(R.drawable.ic_launcher_icon)
        .setContentTitle("Birthday Upcoming for " + name)
        ...
