要解决Android通知未显示为消息的问题,您可以尝试以下方法:
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, channelId)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("Notification Title")
.setContentText("Notification Message")
.setPriority(NotificationCompat.PRIORITY_HIGH);
检查您的设备通知设置,确保您的应用的通知权限已启用。
确保您在Firebase Cloud Messaging服务中正确设置了通知消息的标题和内容。
{
"to": "device_token",
"notification": {
"title": "Notification Title",
"body": "Notification Message"
}
}
public class MyFirebaseMessagingService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
// 处理通知消息
if (remoteMessage.getNotification() != null) {
String title = remoteMessage.getNotification().getTitle();
String message = remoteMessage.getNotification().getBody();
showNotification(title, message);
}
}
private void showNotification(String title, String message) {
// 创建并显示通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle(title)
.setContentText(message)
.setPriority(NotificationCompat.PRIORITY_HIGH);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, builder.build());
}
}
通过使用上述方法,您应该能够解决Android通知未显示为消息的问题。如果问题仍然存在,请确保您的设备和应用都是最新的,并检查是否有其他可能的错误或冲突。
