退出确认屏幕为Android游戏统一

Question

我正在使用统一制作自己的安卓游戏，我想像这样制作退出确认屏幕：

如何使用c＃进行制作？

Answer 1

您可以像这样访问java.lang.Class和java.lang.Object。

AndroidJavaClass unityPlayer = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");
AndroidJavaObject activity = unityPlayer.GetStatic<  AndroidJavaObject >  ("currentActivity");

从这里你应该能够设置GUI组件，按钮和点击监听器来模仿警报对话框

有关进一步理解，请参阅this post

Answer 2

我为你做了一个小例子

1. 将以下脚本附加到游戏对象（例如画布）
2. 添加到普通用户的根（例如面板）a CanvasGroup组件
3. 添加到退出确认ui的根目​​录（例如面板）a CanvasGroup组件
4. 将两个画布组链接到放置脚本的游戏对象
5. 对于每个按钮（退出，确认是，确认否）添加检查器 一个onclick事件到脚本对应的方法

6. 这就是我想的全部（我试着对代码进行评论 参考），Reference

   public class QuitHandler : MonoBehaviour { 
   
    public CanvasGroup uiCanvasGroup;
    public CanvasGroup confirmQuitCanvasGroup;
   
    // Use this for initialization
    private void Awake()
    {
        //disable the quit confirmation panel
        DoConfirmQuitNo();
    }
   
    /// <summary>
    /// Called if clicked on No (confirmation)
    /// </summary>
    public void DoConfirmQuitNo()
    {
        Debug.Log("Back to the game");
   
        //enable the normal ui
        uiCanvasGroup.alpha = 1;
        uiCanvasGroup.interactable = true;
        uiCanvasGroup.blocksRaycasts = true;
   
        //disable the confirmation quit ui
        confirmQuitCanvasGroup.alpha = 0;
        confirmQuitCanvasGroup.interactable = false;
        confirmQuitCanvasGroup.blocksRaycasts = false;
    }
   
    /// <summary>
    /// Called if clicked on Yes (confirmation)
    /// </summary>
    public void DoConfirmQuitYes()
    {
        Debug.Log("Ok bye bye");
        Application.Quit();
    }
   
    /// <summary>
    /// Called if clicked on Quit
    /// </summary>
    public void DoQuit()
    {
        Debug.Log("Check form quit confirmation");
   
        //reduce the visibility of normal UI, and disable all interraction
        uiCanvasGroup.alpha = 0.5f;
        uiCanvasGroup.interactable = false;
        uiCanvasGroup.blocksRaycasts = false;
   
        //enable interraction with confirmation gui and make visible
        confirmQuitCanvasGroup.alpha = 1;
        confirmQuitCanvasGroup.interactable = true;
        confirmQuitCanvasGroup.blocksRaycasts = true;
    }
   
    /// <summary>
    /// Called if clicked on new game (example)
    /// </summary>
    public void DoNewGame()
    {
        Debug.Log("Launch a new game");
    }
