android - 单击推送通知时如何打开 Activity ？

Question

目前我正在我的项目中处理推送通知。当推送通知显示时，我想在单击通知时打开 Mynotification Activity ，但它总是打开 MainActivity 为什么？我也为此谷歌和 SO 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 list 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>

据我所知，这段代码在应用程序位于前台时运行。当它在后台时，Firebase 将通知发送到系统托盘。我遇到过类似的问题。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 Intent。我利用这种技术来读取自定义字符串(从 firebase 消息控制台打开高级选项并将键指定为“item”，将值指定为“MyNotification”)。 从主 Activity 中读取此字符串并将控件重定向到 MainActivity::onCreate() 方法中的适当 Activity

//private String ITEM = "item";
@Override
protected void onCreate(Bundle savedInstanceState) {
    //Parse the input passed to the activity
    Intent intent = getIntent();
    String input = intent.getStringExtra(ITEM);
    //Redirect to MyNotification
    Intent redirect = new Intent(this, MyNotification.class);
    startActivity(redirect);
}
