Android GCM 通知：无标题

Question

我正在构建一个 Android 应用程序，目前正在处理通知。我正在使用 Google 云消息服务，为此我编写了以下 PHP 代码：

<?php
define('API_ACCESS_KEY', 'blablabla');
$registrationIds = array($this->deviceId);

$data = array
(
    'title' => 'My Title',
    'message' => 'My message',
    'subtitle' => 'This is a subtitle. subtitle',
    'tickerText' => 'Ticker text here...Ticker text here...',
    'vibrate' => 1,
    'sound' => 1
);

$fields = array
(
    'registration_ids' => $registrationIds,
    'data' => $data
);

$headers = array
(
    'Authorization: key=' . API_ACCESS_KEY,
    'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://android.googleapis.com/gcm/send');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
curl_exec($ch);
curl_close($ch);

当我执行此 php 文件时，我会在我的 Android 设备上收到通知，如您在以下屏幕截图中所见。消息文本没问题。 android screenshot 但问题是通知的标题不是我在负载中写的 'My Title'，而是 'GCM Message'（看起来像默认的 GCM 标题）。尝试了很多不同的东西，但没有弄明白。

有什么我错的想法吗？谢谢

-------- 解决方案--------

我完全忘记了这必须在 android 端处理...解决方案是在 MyGcmListenerService 中自定义 sendNotification() 方法来处理额外数据：

private void sendNotification(String title, String message) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

感谢解答！

为了设置自定义通知标题，您应该在 GcmListenerService 的 onMessageReceived(String form, Bundle data) 方法中创建自己的通知 class...我为创建自定义通知所做的工作在以下代码：

public class MyGcmListenerService extends GcmListenerService {

private PendingIntent resultPendingIntent;

@Override
public void onMessageReceived(String from, Bundle data) {
    NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.app_logo)
                .setContentTitle(data.getString(getResources().getString(R.string.notification_title)))
                .setContentText(data.getString(getResources().getString(R.string.notification_body)))
                .setDefaults(Notification.DEFAULT_VIBRATE)
                .setContentIntent(resultPendingIntent);

        int mNotificationId = 001;
        NotificationManager mNotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        mNotifyMgr.notify(mNotificationId, nBuilder.build());
  }
 }

在 setContentTitle 中设置自定义通知标题的位置。
