Exception:

 under Caused by: Java. Lang. ClassCastException: com. Google. Gson. Internal. LinkedTreeMap always be cast to com. Xx. Xx. The entity. The response. VehicleBindingList 

Request the results Shared ResponseResult Result=new Gson (). FromJson (response, gsonType);

Problem: generic do not specify a specific type,

Want to ask how to solve, to share fromJson this line of code,

Request the results analysis, sharing the jsonHttpWithData method, Class Clazz now don't have access to, useful to the before,
Why not use the

 return new ParameterizedType () {
@ Override 
The public Type [] getActualTypeArguments () {
Return the args. 
} 

@ Override 
The public Type getRawType () {
Return raw; 
} 

@ Override 
The public Type getOwnerType () {

} 
}; 

No such specified directly reason is: the data not only the object, also may be List
