处理android通知内的按钮

我在通知中添加了一个按钮

但是我不知道如何在点击它时调用它。

我尝试了类似https://code.google.com/p/languagepickerwidget/source/browse/trunk/trunk/src/org/gnvo/langpicker/LangPicker.java的方法,因为它也使用了RemoteViews对象,但是当我点击按钮时没有任何反应。

这就是我目前所拥有的:

private void createNotification(){
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager notificationManager = (NotificationManager) getSystemService(ns);

    Notification notification = new Notification(R.drawable.ic_launcher, null, System.currentTimeMillis());
    RemoteViews notificationView = new RemoteViews(getPackageName(), R.layout.notification_switch);

    //the intent that is started when the notification is clicked (works)
    Intent notificationIntent = new Intent(this, SettingsActivity.class);
    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

    notification.contentView = notificationView;
    notification.contentIntent = pendingNotificationIntent;
    notification.flags |= Notification.FLAG_NO_CLEAR;

    //this is the intent that is supposed to be called when the button is clicked
    Intent switchIntent = new Intent(this, switchButtonListener.class);
    PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, switchIntent, 0);

    notificationView.setOnClickPendingIntent(R.id.buttonswitch, pendingSwitchIntent);

    notificationManager.notify(1, notification);
}

public static class switchButtonListener extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("TAG", "test");
    }

}

我可以使用按钮开始一个活动,但我没有成功让它调用一个简单的函数。最好的方法是什么?

修改 我发现我必须在AndroidManifest.xml中注册“switchButtonListener”

<receiver android:name="SettingsActivity$switchButtonListener" />

后来我发现我也可以使用这样的代码来实现相同的功能,而无需修改清单。

switchButtonListener = new SwitchButtonListener();
registerReceiver(switchButtonListener, new IntentFilter(SWITCH_EVENT));

public class switchButtonListener extends BroadcastReceiver {
@Override
    public void onReceive(Context context, Intent intent) {
        Log.d("TAG", "test");
    }

}

Intent switchIntent = new Intent(LangService.SWITCH_EVENT);
PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(context, 0, switchIntent, 0);

notificationView.setOnClickPendingIntent(R.id.buttonswitch, pendingSwitchIntent);


请注意,这样我可以声明没有静态属性的switchButtonListener类(如果不是静态的,它会在前面的例子中崩溃)给我更多的灵活性。
不要忘记稍后调用unregisterReceiver()。
