如何從一個活動

Question

訪問的AsyncTask定義的值我有這樣的代碼

@Override 
public void onCreate(Bundle savedInstanceState) { 
    addItemsOnSpinnerOrgaLevel(); 

     btn_getReport.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View v) { 

      //How can i access map and list defined in orgaLevelTask(AsyncTask)??? 
      Like 
      String option = parent.getItemAtPosition(pos).toString();    
      int orgaCode = orgaLevelMap.get(option); 

      // Both are defined in AsyncTask ?? 

    }); //end of anonymous class 

} //end of onCreate() 

public void addItemsOnSpinnerOrgaLevel() { 

    orgaLevelTask = new OrgaLevelTask(AccountReportActivity.this, spinner_orgaLevel, spinner_branch, txt_extra, txt_extra1);  
    orgaLevelTask.execute(); 

} //end of addItemsOnSpinnerOrgaLevel() 

在的AsyncTask onPostExecute（）方法I具有

@Override 
protected void onPostExecute(ArrayList<OrgaLevel> result) {  
    super.onPostExecute(result);       
    if (result != null) {    
     addItemsOnSpinnerOrgaLevel(result);          
    } 
    dialog.dismiss(); 
} //end of onPostExecute() 

public void addItemsOnSpinnerOrgaLevel(ArrayList<OrgaLevel> result) { 

    orgaLevelElementslist = new ArrayList<String>(); 
    orgaLevelElementslist.add("All"); 
    orgaLevelMap = new HashMap<String, Integer>(); 
    orgaLevelMap.put("All", 0); 

    for (int i=0; i<result.size(); i++) { 

     OrgaLevel orgaLevelRecord = (OrgaLevel) result.get(i); 
     String key = orgaLevelRecord.getOrgaName(); 
     String value = orgaLevelRecord.getOrgaCode(); 

     orgaLevelMap.put(key, Integer.parseInt(value));    
     orgaLevelElementslist.add(key); 

    } //end of for() 

    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(accountReportActivity, android.R.layout.simple_spinner_item, orgaLevelElementslist); 
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    spinner_orgaLevel.setAdapter(dataAdapter); 

    setSpinnerOrgaLevelListener(); 

} //end of addItemsOnSpinnerOrgaLevel() 

private void setSpinnerOrgaLevelListener() { 

    spinner_orgaLevel.setOnItemSelectedListener(new OnItemSelectedListener() { 

     @Override 
     public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {    
      String option = parent.getItemAtPosition(pos).toString();    
      int orgaCode = orgaLevelMap.get(option);    
      subOrgaLevelTask = new SubOrgaLevelTask(accountReportActivity, spinner_branch, orgaCode);  
      subOrgaLevelTask.execute();    

     } //end of onItemSelected() 

    }); //end of anonymous class 

} //end of setSpinnerOrgaLevelListener() 

在subOrgaLevelTask​​我也有相同的散列映射就像這堂課一樣。你可以看到我想要做的是，把一個關鍵的價值放在微調。所以當我的btn_getReport按鈕得到點擊，然後我得到所選項目的值。就像所有被選中，然後我得到0等等。這個關鍵的價值是工作。問題是當btn_getReport得到點擊，然後我如何獲得所選項目的值。因爲我在後臺線程中填充項目（在OrgaLevelTask​​和SubOrgaLevelTask​​中），我的按鈕在Activity中。那麼我怎麼做，當按鈕點擊，然後我從OrgaLevelTask​​和SubOrgaLevelTask​​中定義的地圖的值？

感謝

好，使他們在orgaLevelTask​​公衆，只需訪問它們。 orgaLevelTask​​應該是你activity類中的一個變量。你試過了嗎？任何錯誤？

您必須確保orgaLevelTask​​成員將在線程安全的方式，使它們公開，我可以訪問它訪問
