The JSONObject you provided is from the popular org.json library which contains a constructor like your example.您提供的JSONObject来自流行的org.json库，其中包含与您的示例类似的构造函数。
So simply switch to this lib.所以只需切换到这个库。

What it seems, is that you are importing the wrong library.看起来，您正在导入错误的库。 The library that you are using doesn't have a constructor that receives a string parameter only a boolean:您正在使用的库没有仅接收字符串参数的构造函数 boolean：
http://json-lib.sourceforge.net/apidocs/jdk15/net/sf/json/JSONObject.html#JSONObject(boolean) http://json-lib.sourceforge.net/apidocs/jdk15/net/sf/json/JSONObject.html#JSONObject(boolean)
The library that you are trying to use when you are initializing a new instance of JSONObject is from Google:您在初始化JSONObject的新实例时尝试使用的库来自 Google：
https://developer.android.com/reference/org/json/JSONObject#JSONObject(java.lang.String) https://developer.android.com/reference/org/json/JSONObject#JSONObject(java.lang.String)
