这需要花费很多时间来获取数据json.当删除并再次安装它将json在1分钟内得到,当我再次点击按钮,json它需要这么多时间,仍然数据没有进入listview

这是我的异常代码

这是java文件中的json代码:

progress = ProgressDialog.show(MainActivity.this, "dialog title", "dialog message", true);
Toast.makeText(MainActivity.this, "ok", Toast.LENGTH_LONG).show();

    if (isNetworkAvailable()) {

        String url = "ConstantValue.URL";
        RequestBody formBody = new …

这里我有一个查询,其中我根据条件获取名称和值,我在列表中存储empid和empname的值

这是一段代码:

List<String> _empid = new ArrayList<String>();
List<String> _empname = new ArrayList<String>();

在这里,我从数据库中获取值:

while (cur1.moveToNext()) {
if (cur1.getString(cur1.getColumnIndex("name"))
        .equalsIgnoreCase("DIS_FIELD_COLLECTION_EXECUTIVE")) {

         _empid.add(cur1.getString(cur1.getColumnIndex("value")));

   } else if (cur1.getString(cur1.getColumnIndex("name"))
                  .equalsIgnoreCase("FIELD_EXECUTIVE_NAME")) {

         _empname.add(cur1.getString(cur1.getColumnIndex("value")));

   }
}

 for (int i = 0; i < _empid.size(); i++) {
          HashMap<String, String> map = new HashMap<String, String>();
          map.put("id", _empid.get(i));
          map.put("name", _empname.get(i));

          Log.e("forloop", _empid.get(i));
          Log.e("forloop", _empname.get(i));

          emp.add(map);
          adp_emp = new Listadapter_emp(emp, Tracker_filter_Activity.this);
                        lst_employee.setAdapter(adp_emp);
}

这里的输出是这样的
