模型类中的数组列表，但清除了数组列表

Question

我只是用model class创建了arraylist。但是，当数据设置为模型时，最后的索引值数据将存储在模型中。 对所有列表对象重复设置的最后一个响应索引值 主模型列表清晰，但数组列表不清楚。 抱歉语法错误，这是我在堆栈上的第一个问题。

这是我的活动代码

List<Search> search;
List<SegmentData> segmentData;


//on create

private void search()
{
    //webservice
    postJsonObject,
        new Response.Listener<JSONObject>()
        {
            @Override
            public void onResponse(JSONObject jsonObject)
            {
                loading.dismiss();
                if(search==null)
                {
                    search=new ArrayList<>();
                }
                else
                {
                    search.clear();
                }


                try
