Is this POST or response ? 这是POST还是response ？ Your JSON looks fine. 您的JSON看起来不错。 Not familiar with the API but I think it may be one of four things: 我不熟悉API，但我认为这可能是以下四件事之一：
If posting you may want to convert this into a javascript object not a JSON object.
如果发布，则可能需要将其转换为javascript对象而不是JSON对象。 AccountType:"15516321",CustomerName:"1MACMONSAM NICOLAS",Currentbalance:"1100,000.00",AccountKey:"", ...
AccountType：“ 15516321”，CustomerName：“ 1MACMONSAM NICOLAS”，Currentbalance：“ 1100,000.00”，AccountKey：“”，... You may have exceeded the amount of data based on how you are sending/receiving the object.
根据您发送/接收对象的方式，您可能已经超出了数据量。 If you look in your dev console is the JSON string erroring out?
如果您在开发人员控制台中查看，JSON字符串是否出错？ If the string object is bad the dev console typically tells you. 如果字符串对象不好，则开发控制台通常会告诉您。 Maybe you have to encode the object. 也许您必须对对象进行编码。 Your class is not properly defined so it cannot handle the data
您的课程定义不正确，因此无法处理数据
EDIT 编辑
Since this is a response you will be able to determine whether or not your server-side class object is handling the data correctly. 由于这是响应，因此您将能够确定服务器端类对象是否正确处理了数据。 Since you have nested array I am almost guessing the class object needs its properties updated. 由于您具有嵌套数组，因此我几乎猜到该类对象需要更新其属性。 If it makes it to your browser you can see the object using Dev Console which I doubt that is the cas since your stack trace identifies the issue. 如果它进入您的浏览器，则可以使用Dev Console看到该对象，我怀疑这是cas，因为您的堆栈跟踪可确定问题所在。

Your model class is wrong.. You should have same variable names as the key of json. 您的模型类是错误的。您应该使用与json键相同的变量名。 Like for CustomerName you should have CustomerName as variable in your model class. 与CustomerName一样，您应该在模型类中将CustomerName作为变量。 Or 要么
Use this http://www.jsonschema2pojo.org/ . 使用此http://www.jsonschema2pojo.org/ 。 It converts you json to POJO... 它将您将json转换为POJO ...

The Json does not contain ClientNames field and hence it would be populated as null in the deserialized Object. Json不包含ClientNames字段，因此它将在反序列化的对象中填充为null。
From your log the following line throws Null Pointer as its previous statement is logged properly. 在您的日志中，由于正确记录了前一条语句，因此以下行将引发Null指针。 Log.e("Name", checklist.getClientNames()); Log.e（“ Name”，checklist.getClientNames（））;
This means that Log.e function gets checklist.getClientNames() as null and throws NPE while trying to work on it. 这意味着Log.e函数获取checklist.getClientNames（）为null并在尝试对其进行操作时抛出NPE。
Try adding the ClientNames field in JSon and it would work fine. 尝试在JSon中添加ClientNames字段，它将正常工作。
