Android，無法讓靜態getter setter屬性工作？

Question

我嘗試這個...

public class Info { 
    private static Info ourInstance = new Info(); 
    public static Info getInstance() { return ourInstance; } 

    private static int currentIndex; 

    public static void setCurrentIndex(int i) { 
     Log.d("DEV", "setter!"); 
     currentIndex = i; 
     // do other work here 
    } 

    public static int getCurrentIndex() { 
     Log.d("DEV", "getter!"); 
     return currentIndex; 
    } 

    private Info() { 
     Log.d("DEV", "class initialized no problem..."); 
     currentIndex = 42; // just doesn't work, only sets the field 
    } 

} 

任何其他類

...

Info.currentIndex = 666; // just doesn't work 

這是行不通的 - 什麼可能的問題是什麼？試了一切。

如果你打算最終這樣做，爲什麼要定義setter/getter？

Info.currentIndex = 666; 

如果是這樣，那麼改變CURRENTINDEX知名度，公衆...

，甚至更好，是一致的代碼，做

Info.setCurrentIndex(666);
