如何在Android Firebase數據庫中爲變量設置不同的名稱？

Question

我有一個叫「someThing」的課。我需要將該課程保存到Firebase，而不是「某些東西」，而是「some_thing」。我可以用HashMap保存它，但是我不清楚如何獲取值（主要是用於適配器）。

public class Something { 

    private int someThing; 

    public Something(int someThing) { 
    this.someThing = someThing; 
    } 

    public int getSomeThing() { 
    return someThing; 
    } 

    public void setSomeThing(int someThing) { 
    this.someThing = someThing; 
    } 

} 

將數據轉換成散列映射保存：

public Map<String, Object> toMap() { 
    HashMap<String, Object> result = new HashMap<>(); 
    result.put("some_thing", something_value); 
    return result; 
} 

但如何將它們回裝入適配器？適配器是基本適配器：

public class SomethingAdapter extends ArrayAdapter<Something> { 
    public SomethingAdapter(Context context, int resource) { 
    super(context, resource); 
    } 
} 

Answer 1

您可以使用火力地堡註解@PropertyName

Answer 2

感謝到Ahmed Abidi，這裏是解決方案：

public class Something { 

@PropertyName("some_thing") 
private int someThing; 

public Something(int someThing) { 
this.someThing = someThing; 
} 

@PropertyName("some_thing") 
public int getSomeThing() { 
return someThing; 
} 

@PropertyName("some_thing") 
public void setSomeThing(int someThing) { 
this.someThing = someThing; 
} 

}
