android - 将ArrayList元素传递给下一个Intent

如果有人可以帮助我，我想将ArrayList元素传递给下一个Intent！

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);

                }

最佳答案

这样做：

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);
}

要么

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);
}
