Question

我正在使用PhoneBap的StatusBarNotification插件（Android）来发送通知。现在我想在特定的时间到这个，从我读过的，我必须使用Android的AlarmManager。我尝试了一些方法，但似乎无法让它起作用。

关于我如何做到这一点的任何建议？

编辑：我可以收到通知，以显示我是否将onReceive（）中的代码放到showNotification（）中。问题似乎是接收器没有收到Alarm-thingy。可能是因为我在IntentFilter中没有正确的操作。

这是我的代码。我从Phonegap的StatusBarNotification插件构建它，找到了here

public class StatusBarNotification extends Plugin {
//  Action to execute
public static final String ACTION="notify";

private Context context;
BroadcastReceiver receiver;

public StatusBarNotification() {
    this.receiver = null;
}

public void setContext(PhonegapActivity ctx) {
    super.setContext(ctx);
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction(); //Dunno what to put here
    if(receiver == null) {
        this.receiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                Log.d("Notification", "inside onReceive");
                /*int icon = R.drawable.notification;
                long when = System.currentTimeMillis();
                NotificationManager manager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

                Intent notificationIntent = new Intent(context, context.getClass());
                PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
                Notification noti = new Notification(icon, "NOTIFICATION", when);
                noti.setLatestEventInfo(context, "TITLE", "TEXT", contentIntent);
                manager.notify(1, noti);
                */
            }
        };
        ctx.registerReceiver(this.receiver, intentFilter);
    }
}

/**

 *

 *  @param data         JSONArray of arguments to the plugin
 *  @param callbackId   The callback id used when calling back into JavaScript
 *
 *  @return             A PluginRequest object with a status
 * */
@Override
public PluginResult execute(String action, JSONArray data, String callbackId) {
    String ns = Context.NOTIFICATION_SERVICE;

    context = this.ctx.getApplicationContext();

    PluginResult result = null;
    if (ACTION.equals(action)) {
        try {

            String title = data.getString(0);
            String body = data.getString(1);
            Log.d("NotificationPlugin", "Notification: " + title + ", " + body);

            showNotification(title, body);
            result = new PluginResult(Status.OK);
        } catch (JSONException jsonEx) {
            Log.d("NotificationPlugin", "Got JSON Exception "
                    + jsonEx.getMessage());
            result = new PluginResult(Status.JSON_EXCEPTION);
        }
    } else {
        result = new PluginResult(Status.INVALID_ACTION);
        Log.d("NotificationPlugin", "Invalid action : "+action+" passed");
    }
    return result;
}

/**
 *  Displays status bar notification
 *
 *  @param contentTitle Notification title
 *  @param contentText  Notification text
 * */
public void showNotification( CharSequence contentTitle, CharSequence contentText) {
    Intent intent = new Intent(ctx, ctx.getClass());
    PendingIntent pi = PendingIntent.getBroadcast(ctx, 1234, intent, PendingIntent.FLAG_CANCEL_CURRENT);
    Calendar cal = Calendar.getInstance();
    AlarmManager am = (AlarmManager) ctx.getSystemService(ctx.ALARM_SERVICE);
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pi);

}

public void onDestroy() {
    if (this.receiver != null) {
        try {
            this.ctx.unregisterReceiver(this.receiver);
        } catch (Exception e) {
            Log.e("LOG TAG", "Error unregistering network receiver: " + e.getMessage(), e);
        }
    }
}

}

Answer 1

您应该使用LocalNotification.js为特定日期和时间设置警报。因为我使用它并且工作正常。

Answer 2

您可能需要编写可以执行AlarmManager操作的PhoneGap插件。

以下是插件中BroadcastReceivers的一些示例：

https://github.com/callback/callback-android/blob/master/framework/src/com/phonegap/NetworkManager.java

https://github.com/phonegap/phonegap-plugins/blob/master/Android/PhoneListener/PhoneListener.java

带有phonegap的AlarmManager
