從領域文件加載數據

Question

我喜歡使用getter加載我的json中的整數，如下所示，但它不起作用。難道我做錯了什麼

int position; 

Setting setting = new Setting(); 
position = setting.getRadioPosition(); 

我的境界類如下：

public class Setting extends RealmObject { 
    @Required 
    private Integer RadioPosition; 

    public Integer getRadioPosition() { 
    return RadioPosition; 
    } 

    public void setRadioPosition(Integer radioposition) { 
    RadioPosition = radioposition; 
    } 

} 

我的JSON文件如下：

[ 
    { 
"Notification": "True", 
"RadioPosition": 1 
    } 
]

我應該補充下面先加載所有數據。

RealmResults test = realm.where（Setting.class）.findAll（）;

以下是我如何插入我的兩個JSON文件：

private void loadJsonFromStream() throws IOException { 

    InputStream stream = getAssets().open("school.json"); 
    InputStream streamSetting = getAssets().open("setting.json"); 

    realm.beginTransaction(); 
    try { 
     realm.createAllFromJson(School.class, stream); 
     realm.createAllFromJson(Setting.class, streamSetting); 
     realm.commitTransaction(); 
    } catch (IOException e) { 
     // Remember to cancel the transaction if anything goes wrong. 
     realm.cancelTransaction(); 
    } finally { 
     if (stream != null && streamSetting != null) { 
      stream.close(); 
      streamSetting.close(); 


     } 
    } 

}
