Question

大家好，我有以下代码从服务器上撤回一些数据，当我点击任何项目时，它会显示从服务器检索的ID。而不是在吐司中显示我想传递给另一个活动。这是原始代码

public class Test extends ListActivity  {
      Prefs myprefs = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listplaceholder);
        this.myprefs = new Prefs(getApplicationContext());
        // install handler for processing gui update messages
        ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
       JSONObject json = JSONfunctions.getJSONfromURL("http://midsweden.gofreeserve.com/proj/androidjson.php?identifier=" + 
        Test.this.myprefs.getPersonalno());

        try{

            JSONArray  earthquakes = json.getJSONArray("services");

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

                map.put("id",  String.valueOf(i));
                map.put("pic", "Service name : " + e.getString("employeepic"));
                map.put("serviceinfo", "" +  e.getString("employeename")+ " : "+ e.getString("starttime")
                        +" To " +  e.getString("endtime"));
                mylist.add(map);            
            }       
        }catch(JSONException e)        {
             Log.e("log_tag", "Error parsing data "+e.toString());
        }

        ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.test, 
                        new String[] { "servicename", "serviceinfo" }, 
                        new int[] { R.id.item_title, R.id.item_subtitle });

        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);                   
                Toast.makeText(Test.this, "ID '" + o.get("id") + "' was clicked.", Toast.LENGTH_SHORT).show(); 

            }
        });

    }

我正在尝试调整此代码，但每次＆＃34;强制关闭＆＃34;

Intent intent = new Intent(Test.this, passing.class);
intent.putExtra("Employename", employeename);
startActivity(intent);

以下列方式完成id。但现在如何用hireename取代它

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);                   
            Intent intent = new Intent(Test.this, passing.class);
            intent.putExtra("id", id);
            startActivity(intent); 

            }
        });

}

您好我向您提出了几个问题...您是否尝试在您拥有Toast声明的地方插入新的活动部分。如果是这样，插入后强制关闭对话框来了..请检查你是否有名称传递的类，并在清单中定义了一个活动...如果你仍然得到强制关闭anr只是发布你的logcat这将有所帮助我们来解决你的问题..

在活动之间传递价值
