因爲我是新手，我不知道是什麼問題，我做了谷歌，但我並沒有得到解決，任何人都可以幫我嗎？

嗨維韋克，做你檢查你的反應？它是有效的Json，它似乎是有效的，即使我建議在jsonlint.org檢查一次。 –

是的，我在jsonlint.org檢查過。它是有效的JSON。 –

關於你的評論。你需要改變你的模型。您的LaboratoryList應該只包含一個配置文件。

將其更改爲：

private LaboratoryProfile laboratory_profile; 

public LaboratoryProfile getLaboratory_profile() { 
    return laboratory_profile; 
}

thanx很多先生，它爲我工作。 –

歡迎您。如果你喜歡，你也可以投票;） –

在你的LaboratoryList.java中有一個配置文件列表，但是你的JSON並不代表這個。它是一個JSON對象。將其更改爲數組或使配置文件列表只有一個配置文件。

你JSON的輪廓應該是這樣的：

"laboratory_profile":[ 
     { 
      "head_name":"MR X", 
      "degree_name":"MBBS", 
      "speciality":null, 
      "license_number":"123456", 
      "laboratory":"Diagnostic" 
     } 
    ]

你能幫我嗎我該怎麼辦？正如我已經提到，我是一個新手，所以我沒有太多的想法。 –

我編輯了我的答案。 –

還有其他方法嗎？不改變JSON我們可以做到嗎？ –

改變你的LaboratoryList班線

private ArrayList<LaboratoryProfile> laboratory_profile = new ArrayList<LaboratoryProfile>();

這個

private LaboratoryProfile laboratory_profile;

，並刪除以前的getter和setter與新的。你完成了
