如何在Android中的ListView中获取特定textView的值？

Question

在我的应用程序中,我需要根据单击的列表从一个活动移动到另一个活动.在每个列表视图中将有三个textview,即:Emp_id,Emp_name,Emp_address,因此每当我点击应该移动到相应Emp_id的下一个活动的特定列表时.所以在这里我想抓住Emp_id,这是我无法做到的.我已经尝试了很多,但只获得了第一个Emp_id而不是我点击的列表.

码:

ArrayList<HashMap<String, String>> mylist2 = new ArrayList<HashMap<String, String>>();

        try{
            JSONObject jObj = new JSONObject(Mydetail);
            JSONArray data = jObj.getJSONArray("mydata");

            for(int i=0;i<data.length();i++){                       
                HashMap<String, String> map = new HashMap<String, String>();    
                JSONObject e = data.getJSONObject(i);

                map.put("id", String.valueOf(i));
                map.put("Eid", "" + e.getString("E_id"));
                map.put("Ename", "" + e.getString("E_name"));
                map.put("Eaddress", "" + e.getString("E_address"));
                mylist2.add(map);
            }       
        }catch(JSONException e)        {
             Log.e("log_tag", "Error parsing data "+e.toString());
        }

         ListAdapter adapter = new SimpleAdapter(this, mylist2 , R.layout.datalist,
                                  new String[] { "Eid", "Ename", "Eaddress" }, 
                                  new int[] {  R.id.TextView1,R.id.TextView2e,R.id.TextView3 });
                                  setListAdapter(adapter);


        final ListView lv = getListView();
        lv.setTextFilterEnabled(true);  
        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {              
                @SuppressWarnings("unchecked")
                HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);                   
                //String val = o.get("id");

                Pnm = (TextView)findViewById(R.id.TextView1);
                 String str = ((TextView)Pnm).getText().toString();


                Toast.makeText(projects.this, str,Toast.LENGTH_LONG).show();

                Intent newActivitySecond = new Intent(projects.this, modules.class);     
                projects.this.startActivity(newActivitySecond);


            }
        });

谢谢

试试这样:

 ListView lv_ArchivePartylist;

    lv_ArchivePartylist = (ListView)findViewById(R.id.archive_ListView01);
            lv_ArchivePartylist.setOnItemClickListener(new OnItemClickListener()
                {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
                    // TODO Auto-generated method stub
                    String message = view.findViewById(R.id.txt_box1).getText().toString;
                    Toast.makeText(Activityname.this, message, Toast.LENGTH_SHORT).show();

    }
    }

    });
