问题描述

我从这种反应越来越姓名和日期在我的微调,现在我所想的,如果用户从微调百合选择,然后我想在字符串OCC价值,但我没有得到它,下面是我的反应和code,任何一个可以告诉我,什么是问题

  [
    {
        friend_id:1,
        user_spoc_dob:1993年11月11日,
        状态:真正的,
        spouse_name:百合,
        OCC:SPOC
    },
    {
        friend_id:1,
        user_mother_dob:1974年12月12日,
        状态:真正的,
        mother_name:SITA,
        消息:详细地址不可用,
        OCC:妈妈
    },
    {
        friend_id:1,
        user_father_dob:1972年11月19日,
        状态:真正的,
        father_name:公羊,
        消息:详细地址不可用,
        OCC:爸爸
    },
    {
        friend_id:1,
        user_dob:1994年2月20日,
        状态:真正的,
        user_fname:苏,
        OCC:杀破狼
    }

    }


解决方案

下面:

  testlist =新的ArrayList<串GT;();
如果(OCCS!= NULL)
   testlist.add(OCCS);

这些线路引起的问题,因为 testlist 正在初始化每次。移动 testlist 初始化出端 for循环

  jsonObj =新JSONArray(jsonStr);
testlist =新的ArrayList<串GT;();
的for(int i = 0; I< jsonObj.length();我++){   // ...您code这里JSON解析
   如果(OCCS!= NULL)
     testlist.add(OCCS);
   其他
     testlist.add();
}

        }

        protected void onPostExecute(ArrayList<String> result) {
            super.onPostExecute(result);
            pDialog.dismiss();
            arrallstates = new String[statedata.size()]; // you can also use "result" array instead
            for (int index = 0; index < statedata.size(); index++) {
                arrallstates[index] = statedata.get(index);// or result.get(index);
                //arrallstates[index] =testlist.get(index);
            }
            // pass arrConuntry array to ArrayAdapter<String> constroctor :
            adapterallstates = new ArrayAdapter<String>(
                    WishFriendsFamily.this.getActivity(),
                    android.R.layout.simple_spinner_dropdown_item, arrallstates);
            System.out.println("adpttest" + adapterallstates);
            staticSpinner.setAdapter(adapterallstates);

            staticSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {

                        String oocs=testlist.get(i).toString();
                    System.out.println("slected ocs" + oocs);
                }
                @Override
                public void onNothingSelected(AdapterView<?> adapterView) {

                }
            });
        }
    }

解决方案

Here:

testlist=new ArrayList<String>(); 
if(occs!=null)    
   testlist.add(occs);

these lines causing issue, because testlist is initializing every time. move testlist initialization out-side for-loop:

jsonObj = new JSONArray(jsonStr);
testlist=new ArrayList<String>();
for (int i = 0; i < jsonObj.length(); i++) {

   //... your code here for json parsing 
   if(occs!=null) 
     testlist.add(occs);
   else
     testlist.add("");
}
