java - GSON java.lang.IllegalArgumentException：类 android.widget.TextView 声明了多个名为 mMinWidth 的 JSON 字段

Question

我正在做什么：我正在尝试使用 GSON 对自定义对象的 ArrayList 进行序列化。我正在制作一个聊天应用程序，所以我需要保存对话。

我已经查看了同一个问题的许多不同解决方案，并且我知道答案.. GSON 正在尝试序列化一个同时在子类和超类中的字段对象，但我的情况有点困难，因为我无权访问这些课程中的任何一个。这是我的堆栈跟踪。

int mMinWidth如您所见，它似乎在 TextView 和 View 中都在抱怨，它是超类。我完全迷失了，我不确定我的代码中包含什么，但我会尽力而为。如果您需要更多信息，请发表评论。

导致问题的代码：

public void saveConversationList()
    {
        SharedPreferences sharedPreferences = getSharedPreferences(SharedPrefStrings.SHARED_PREFS, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        Gson gson = new Gson();
        String jsonOne = gson.toJson(ConversationWrapper.conversationsHistoryList); ERROR ON THIS LINE
        String jsonTwo = gson.toJson(ConversationWrapper.activeConversationIDs);
        editor.putString(SharedPrefStrings.CONVERSATION_LIST, jsonOne);
        editor.putString(SharedPrefStrings.CONVERSATION_LIST_IDS, jsonTwo);
        editor.commit();
    }

会话包装类：

public class ConversationWrapper {
    public static ArrayList<Conversation> conversationsHistoryList;
}

会话课：

public class Conversation extends LinearLayout {

    private TextView id_tag_view;

    private TextView contact_name_view;
    private String contact_name;

    private TextView last_message_view;
    private String last_message;

    private ArrayList<MessageContainer> messageHistory;

    public Conversation(Context context) {
        super(context);
        init();
    }

    public Conversation(Context context, String contact_name, String last_message) {
        super(context);
        this.contact_name = contact_name;
        this.last_message = last_message;
        init();
    }

    public Conversation(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public Conversation(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    public Conversation(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
        init();
    }

    private void init()
    {
        inflate(getContext(), R.layout.conversation_preview_view, this);
        this.contact_name_view = (TextView) findViewById(R.id.contact_name_textview);
        this.contact_name_view.setText(this.contact_name);
        this.last_message_view = (TextView) findViewById(R.id.last_message_textview);
        this.last_message_view.setText(this.last_message);
        this.id_tag_view = (TextView) findViewById(R.id.id_tag);
        this.messageHistory = new ArrayList<MessageContainer>();
    }

    public void setContactName(String name)
    {
        this.contact_name = name;
        this.contact_name_view.setText(this.contact_name);
        postInvalidate();
    }

    public void setLastMessage(String lastMessage)
    {
        this.last_message = lastMessage;
        this.last_message_view.setText(this.last_message);
        postInvalidate();
    }

    public void setConversationID(int id)
    {
        this.id_tag_view.setText(id + "");
    }

    public int getConversationID()
    {
        int id = Integer.parseInt(this.id_tag_view.getText().toString());
        return id;
    }

    public void addMessage(MessageContainer mc)
    {
        this.messageHistory.add(mc);
    }

    public ArrayList<MessageContainer> getMessageHistory()
    {
        return this.messageHistory;
    }

}

任何帮助，将不胜感激。谢谢。
