Java Lang Classcastexception Com Google Gson Internal Linkedtreemap

Android Java Lang Noclassdeffounderror Com Google Gson Gson Stack You can iterate through the arraylist to convert each linkedtreemap item to a product item. you can use gson a second time to do the conversion. see example code here: randomgyan …. 由于要保存到shp的是arraylist，所以需要 使用gson 解析，在解析过程中报了如下错误： com.google. gson.internal. linkedtreemap cannot be cast to xxx 原先代码如下： 将list转化为json字符串保存在本地： ** * 保存list * public static void.

Java Lang Classcastexception Com Google Gson Internal Linkedtreemap The error 'java.lang.classcastexception: com.google.gson.internal.linkedtreemap cannot be cast to [your model]' occurs when attempting to cast a json deserialized object to a specific class type in java. Java.lang.classcastexception: com.google.gson.internal.linkedtreemap cannot be cast to com.hsa……. so after banging my head with different types of types like jsonarray, arraylist, jsonobject and even custom model with getters and setters, but nothing helped then finally cracked it to show listview data. json response format from server: {. Java.lang.classcastexception: cannot cast com.google.gson.internal.linkedtreemap to androidx.collection.arraymap. we can fix it either by using map as typetoken or moving to 8.0.77 r8 version. is this a known issue? do we need to update the r8 rules? i tried both the latest versions of r8 in 8.2, 8.1 series and both of them don't work. 本文介绍了在使用gson进行json到list数据对象转换时遇到的`java.lang.classcastexception: com.google.gson.internal.linkedtreemap cannot be cast to user`异常。 问题根源在于gson在处理有泛型的数据类型时需要指定泛型，通过`new typetoken> () {}.gettype ()`来指定类型，或者使用非泛型的实体类包裹。 这两种方法可以避免转换异常。 今天写项目发现了一个用gson做json串回list的数据对象时，报了这个错误，如下. list userlist;.

The classcastexception you're encountering occurs when gson deserializes json objects into a linkedtreemap instead of your specified class. this issue commonly arises when the json structure does not match the expected object design or lacks proper type information. A hashmap implements map interface, the reason i loled is that google has to be different 🙂 so in this case when you convert from json to object using typetoken and specifically state that it is map, fromgson returns com.google.gson.internal.linkedhashtreemap which is not assignable to hashmap.
