目前我正在我的项目中处理推送通知。当推送通知显示我想在单击通知时打开Mynotification活动，但它总是打开MainActivity为什么？我也用谷歌搜索，但找不到正确的答案

这是我的MyFirebaseMessagingService：

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMsgService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        sendNotification(remoteMessage.getNotification().getBody());

    }

    private void sendNotification(String messageBody) {


        Intent intent = new Intent(this, MyNotification.class);
        intent.putExtra("Message",messageBody);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                0);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("Shri Sidhbali Baba")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notificationBuilder.build());
    }
}
这是我的清单文件：

 <activity android:name=".MyNotification"
            android:parentActivityName=".MainActivity">
            <intent-filter>
                <action android:name=".MyNotification" android:label="@string/app_name"/>

                <category android:name="android.intent.category.DEFAULT"/>


            </intent-filter>

        </activity>
单击“推送通知”时如何打开我的通知活动。 感谢您抽出时间…

更新此信息：

 private void sendNotification(String messageBody) {


    Intent intent = new Intent(this, MyNotification.class);
    intent.putExtra("Message",messageBody);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
     PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MyNotification.class), 0);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle("Shri Sidhbali Baba")
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationBuilder.setContentIntent(contentIntent);

    notificationManager.notify(0, notificationBuilder.build());
}
尝试删除清单中的此行

android:parentActivityName=".MainActivity"
编辑1：您可以在此处阅读更多内容

原因是当您调用“MyNotification”活动时，back stack会“自动”将其父活动添加到back stack中，这样您就可以按back返回到“MainActivity”了。好的，这段代码在应用程序位于前台时运行。当它在后台时，Firebase会将通知发送到系统托盘。我曾面临过类似的问题。当它传送到系统托盘时，它总是打开MainActivity。我注意到firebase允许将参数传递给意图。我利用这种技术来读取自定义字符串（从firebase消息控制台打开advance选项，并将键指定为'item'，将值指定为'MyNotification'）。 从主活动中读取此字符串，并从MainActivity:：onCreate（）方法将控件重定向到相应的活动

试试这个

ResourceReady（位图资源，GlideAnimation）上的公共无效@MinWan有何原因？添加此行notificationBuilder.setContentIntent（contentIntent）；setContentIntent（pendingIntent）；更改为setContentIntent（contentIntent）；嘿，我在此处添加此行notificationBuilder.setContentIntent（contentIntent）；让我们来看看。在我的FCM控制台中，高级选项用于删除应用程序…你能告诉我如何添加密钥吗？我指的是控制台中的“新消息”。firebase.google.com->通知单击“高级选项”，你会看到下面的转换事件。这是用于向你的应用程序发送通知的同一个控制台不适用于我。它显示错误无法启动t activity.intent为null。实际上我不想使用外部libs…但感谢您花时间@vishnumm93
