Gson在"$ Types.resolve"上溢出StackOverflow异常

Question

我有一个ArrayList和一个ArrayList,并且在检索自定义对象ArrayList时gson工作正常,但在检索LinearLayout ArrayList时会导致stackOverflow异常.

码:

public Semester(JSONObject json) throws JSONException {

coursesAsString = json.getString(JSON_COURSES);
Type coursesType = new TypeToken<ArrayList<Course>>(){}.
courses = gson.fromJson(coursesAsString, // <--- THIS PART WORKS FINE

courseLayoutArrayAsString = json.getString(JSON_COURSELAYOUTARRAY);
Type courseLayoutArrayType = new TypeToken<ArrayList<LinearLayout>>(){}.getType();
courseLayoutArray = gson.fromJson(courseLayoutArrayAsString, courseLayoutArrayType); // <---- this line
//is where the problem lies. For some reason 
//"gson.fromJson(courseLayoutArrayAsString, courseLayoutArrayType)" causes a stackOverflow exception.

}

这是一个例外:

java.lang.StackOverflowError
        at com.google.gson.internal.$Gson$Types.resolve($Gson$Types.java:375)
        at com.google.gson.internal.$Gson$Types.resolve($Gson$Types.java:380)
        at com.google.gson.internal.$Gson$Types.resolve($Gson$Types.java:375)
        at com.google.gson.internal.$Gson$Types.resolve($Gson$Types.java:380)

它长期以来一直在这样下去.

您正在尝试序列化LinearLayouts？这是非常糟糕的做法.

您应该在这些LinearLayouts中序列化所需的数据,并在反序列化数据时重新创建LinearLayout.
