android - 从 pendingIntent 的堆栈中删除启动器 Activity

Question

我有一些问题。当我的应用程序不在后台(从最近删除)时，一切正常。但是当我的应用程序是最近的，然后我通过通知挂起 Intent 打开“ResponseActivity”时，在“ResponseActivity”上单击后退我进入我的 MainActivity(启动器 Activity )。我已经添加了 FLAG_ACTIVITY_NEW_TASK，但它似乎没有这样做。

    Intent intent = new Intent(this, ResponseActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP   | Intent.FLAG_ACTIVITY_NEW_TASK);

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_launcher_background)
            .addAction(0, "Other", pendingIntent) 
            .setLargeIcon(getCircleBitmap(bitmap))
            .setContentTitle(userDB.getName())
            .setContentText(smallText)
            .setAutoCancel(true)
            .setDefaults(Notification.DEFAULT_ALL)
            .setColor(getResources().getColor(R.color.colorPrimary))
            .setPriority(NotificationCompat.PRIORITY_DEFAULT);


    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel channel = mNotificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID);

        channel.setDescription("");
        channel.enableLights(true);
        channel.setLightColor(Color.RED);
        channel.enableVibration(true);

        mNotificationManager.createNotificationChannel(channel);
    }

    mNotificationManager.notify(1000, mBuilder.build());

        </intent-filter>
    </service>

    <activity android:name=".MainActivity" />
    <activity android:name=".LoginActivity" />

    <activity android:name="verification.MyVerifyPhoneActivity" />
    <activity android:name=".ResponseActivity"
        android:theme="@style/AppTheme2">

    </activity>
</application>

如果您想确保在选择通知时只有 ResponseActivity 在堆栈中，您可以这样做:

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);

代替:

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
