传递的ArrayList元素到下一个意图 [英] Pass ArrayList element to the next Intent

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);
}
