如何从切换组中获取选定的切换？

Question

我已经创建了一个切换组，现在我想用一些最简单的方法检索选定的切换项目。

与我分享您的侧面建议...

编辑： 这里有 ToggleGroup 详细信息：

我正在使用这段代码来检查：

public class RandomMatchMakerPanelController : MonoBehaviour
{


public Sprite defaultPlayerPhoto;
//
[Header ("Player-1")]
public Image player1Photo;
public Text player1NameText;
public Text player1CountryText;
public ToggleGroup player1BallGroup;

[Header ("Player-2")]
public Image player2Photo;
public Text player2NameText;
public Text player2CountryText;
public ToggleGroup player2BallGroup;

void OnEnable ()
{
//      StartCoroutine (CreateRandomMatches ());
        GetSelectedToggle ();
    ShowLocalPlayerDetails ();
}

private void ShowLocalPlayerDetails ()
{
    if (DataCollection.localPlayer.ProfilePhoto == null)
        player1Photo.sprite = defaultPlayerPhoto;
    else
        player1Photo.sprite = DataCollection.localPlayer.ProfilePhoto;
    player1NameText.text = DataCollection.localPlayer.PlayerName;
    player1CountryText.text = DataCollection.localPlayer.Country;
}

private void GetSelectedToggle ()
{
//      Toggle[] ballToggles = player1BallGroup.GetComponentsInChildren<Toggle> ();
    foreach (Toggle toggle in player1BallGroup.ActiveToggles()) {
        Debug.Log ("toggle: "+ toggle.isOn);
    }
    // May have several selected toggles
//      foreach (Toggle toggle in ballToggles) {
//          if(toggle.isOn)
//      }
}

IEnumerator CreateRandomMatches ()
{
    yield return new WaitForSeconds (0.25f);
    RandomMatchMaker matchMaker = GameObject.FindGameObjectWithTag (GameConstants.TAG_NETWORK_MANAGER).GetComponent<RandomMatchMaker> ();
    matchMaker.FindInternetMatch ("Dodgels-");
}

public void OnBackButtonClick ()
{
    SoundManager.Instance.PlayButtonClickSound ();
    Camera.main.SendMessage (GameConstants.ACTIVATE_RANDOM_MATCH_MAKER_PANEL, false, SendMessageOptions.DontRequireReceiver);
    Camera.main.SendMessage (GameConstants.ACTIVATE_RANDOM_PLAYER_GAMEPLAY, false, SendMessageOptions.DontRequireReceiver);
    Camera.main.SendMessage (GameConstants.ACTIVATE_MAIN_MENU_PANEL, true, SendMessageOptions.DontRequireReceiver);
}
}

目前，控制台中没有显示任何内容，但一次一个切换始终保持活动状态。

您可以使用选择组中活动开关集的ActiveToggles()功能来获取所有活动开关。通常，这个集合是由一个独特的Toggle组成的。

using System.Linq;

// ...

public UnityEngine.UI.ToggleGroup ToggleGroup ; // Drag & drop the desired ToggleGroup in the inspector

private void Start()
{
    if( ToggleGroup == null ) ToggleGroup = GetComponent<ToggleGroup>();
}

public void LogSelectedToggle()
{
    // May have several selected toggles
    foreach( Toggle toggle in ToggleGroup.ActiveToggles() )
    {
         Debug.Log( toggle, toggle ) ;
    }

    // OR

    Toggle selectedToggle = ToggleGroup.ActiveToggles().FirstOrDefault();
    if( selectedToggle != null )
        Debug.Log( selectedToggle, selectedToggle ) ;
}
