传递的ArrayList元素到下一个意图

本文介绍了传递的ArrayList元素到下一个意图的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想一个ArrayList元素传递给下一个意向，如果有一个人能帮助我！

{尝试                JSONArray jArray =新JSONArray（结果）;                JSONObject的json_data = NULL;                的for（int i = 0; I＆LT; jArray.length（）;我++）                {                   json_data = jArray.getJSONObject（ⅰ）;                   r.add（json_data.getString（Nom_Serveur））;               }               setListAdapter（新ArrayAdapter＆LT;串GT;（这一点，android.R.layout.simple_expandable_list_item_1，R））;               ListView控件列表= getListView（）;               list.setTextFilterEnabled（真）;               list.setOnItemClickListener（新OnItemClickListener（）{                公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，ARG1查看，                        INT ARG2，长ARG3）{                    意图I =新意图（Serveur_EnPanne.this，Info_serveur.class）;                    i.putExtra（钥匙，??）                    startActivity（ⅰ）;                }

解决方案

做的是这样的：

公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，ARG1观，诠释ARG2，长ARG3）{         意图I =新意图（Serveur_EnPanne.this，Info_serveur.class）;         i.putExtra（钥匙，arg0.getSeletectedItem（）的toString（））;         startActivity（ⅰ）;}

或

公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，ARG1观，诠释ARG2，长ARG3）{         意图I =新意图（Serveur_EnPanne.this，Info_serveur.class）;         i.putExtra（钥匙，r.get（ARG2））;         startActivity（ⅰ）;}

I'd like to pass an ArrayList element to the next Intent, if some one can help me!

try{ JSONArray jArray = new JSONArray(result); JSONObject json_data=null; for(int i=0;i<jArray.length();i++) { json_data = jArray.getJSONObject(i); r.add(json_data.getString("Nom_Serveur")); } setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, r)); ListView list = getListView(); list.setTextFilterEnabled(true); list.setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Intent i = new Intent(Serveur_EnPanne.this, Info_serveur.class); i.putExtra("key", ??) startActivity(i); }

解决方案

do this way:

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Intent i = new Intent(Serveur_EnPanne.this, Info_serveur.class); i.putExtra("key", arg0.getSeletectedItem().toString()); startActivity(i); }

or

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Intent i = new Intent(Serveur_EnPanne.this, Info_serveur.class); i.putExtra("key", r.get(arg2)); startActivity(i); }
