问题描述

我试图从一个活动发送JSON对象数据到其他的活动。我有一个成功的从一个JSON数组填充一个列表视图,但正如我在一个列表项单击,它没有响应。正在对项目点击执行任何操作。我看到一些教程,但它并没有帮助。我需要的列表项的JSON数据发送到另一个活动。任何帮助将是AP preciated。

的ListView填充使用JSON的活动。

  {尝试         jArray =新JSONArray(结果);
         ListView控件的ListView =(ListView控件)findViewById(R.id.listtour_cat);
         listView.setAdapter(新ListViewAdapter(JSONUseActivity.this,jArray));
         listView.setOnItemClickListener(新OnItemClickListener(){            @覆盖
            公共无效onItemClick(适配器视图<>为arg0,ARG1观,诠释ARG2,
                    长ARG3){
                // TODO自动生成方法存根
                尝试{
                    如果(!jArray.isNull(ARG2)){
                           意向意图=新意图(getApplicationContext(),TourDetailActivity.class);
                           intent.putExtra(ID,jArray.optJSONObject(ARG2).getString(tour_id));
                           startActivity(意向);
                     }                }
                赶上(JSONException E){
                       Log.e(log_tag,错误分析数据+ e.toString());
               }            }
        });
       }
       赶上(JSONException E){
               Log.e(log_tag,错误分析数据+ e.toString());
       }  }
        赶上(例外五){
          Log.e(log_tag,在HTTP连接错误!+ e.toString());
  }

目标活动:

 意向意图= getIntent();
字符串rcvid = intent.getStringExtra(ID);
Toast.makeText(getApplicationContext(),rcvid,Toast.LENGTH_LONG).show();


解决方案

转换JsonArray为字符串,然后将其连接到意向ANS发送。

 的JSONObject jObject =新的JSONObject(你的JSON响应);    意图obj_intent =新意图(Main.this,Main1.class);
    束B =新包();
    b.putString(阵列,jObject4.toString());
    obj_intent.putExtras(二);

在哪里jObject4是JSON对象。

获取下一页:

 意图B = getIntent()getExtras()。
        字符串数组= b.getString(阵列);

I am trying to send the json object data from one activity to other activity. I have a listview that is successfully populated from a json array, but as i click on a list item, it is not responding. No action is being performed on item click. I saw some tutorials but it did not helped. I need to send the list item's json data to another activity. Any help would be appreciated.

Activity of listview populated with Json.

       try{

         jArray = new JSONArray(result);
         ListView listView=(ListView)findViewById(R.id.listtour_cat);
         listView.setAdapter(new ListViewAdapter(JSONUseActivity.this,jArray));
         listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                // TODO Auto-generated method stub
                try{
                    if(!jArray.isNull(arg2)){
                           Intent intent = new Intent(getApplicationContext(),TourDetailActivity.class);  
                           intent.putExtra("id", jArray.optJSONObject(arg2).getString("tour_id"));
                           startActivity(intent);    
                     }

                }
                catch(JSONException e){
                       Log.e("log_tag", "Error parsing data "+e.toString());
               }

            }
        });
       }
       catch(JSONException e){
               Log.e("log_tag", "Error parsing data "+e.toString());
       }

  }
        catch (Exception e) {
          Log.e("log_tag","Error in http connection!!" + e.toString());     
  }

Target Activity:

Intent intent = getIntent();
String rcvid = intent.getStringExtra("id");
Toast.makeText(getApplicationContext(), rcvid, Toast.LENGTH_LONG).show();

解决方案

Convert JsonArray to String then attach it to Intent ans send it.

    JSONObject jObject = new JSONObject("Your Json Response");

    Intent obj_intent = new Intent(Main.this, Main1.class);
    Bundle b = new Bundle();                
    b.putString("Array",jObject4.toString());
    obj_intent.putExtras(b);

Where jObject4 is JSON Object.

Get in next Page :

        Intent b = getIntent().getExtras();
        String Array=b.getString("Array");
