android - 如何在从json文件获取的textview中显示数组名称

Question

下面是我的代码我使用两个json文件一个包含数据第二个包含日期问题仅在第二个json文件中我想首先检查json文件中是否存在日期，然后在textview中显示该日期的json数组“标题”在帖子 onPostExecute 中只需检查这一行 if (Vacation_Date.contains(mydate)) { 匹配然后在 onPostExecute 的 textview 中显示该日期的 json 数组“标题”怎么做？？？

   static ArrayList<Long> Category_ID = new ArrayList<Long>();
static ArrayList<String> school_name = new ArrayList<String>();
static ArrayList<String> menu_name = new ArrayList<String>();

static ArrayList<String> dish_name = new ArrayList<String>();
static ArrayList<String> day = new ArrayList<String>();




static ArrayList<Long> Vacation_ID = new ArrayList<Long>();
static ArrayList<String> Vacation_name = new ArrayList<String>();
static ArrayList<String> Vacation_Date = new ArrayList<String>();
