java.lang.ClassCastException: com.google.gson.internal.LinkedTreeMap cannot be cast to xxxxxx
The reason is that when converting ordinary String strings to List objects, the solution can be the following conversion methods:
/**
* Convert a json string to a List containing POJO objects
*
* @param string
* @param cls
* @param <T>
* @return
*/
public static <T> List<T> jsonStringConvertToList(String string, Class<T[]> cls) {
Gson gson = new Gson ();
T[] array = gson.fromJson(string, cls);
return Arrays.asList(array);
}
For example, a Java object MyPOJO.class of your own, then the method is:
jsonStringConvertToList(string,MyPOJO[].class);
