我有这样的代码
@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 AsyncTask onPostExecute() 方法中我有
@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 中，我也有与此类相同的哈希映射。你可以看到我想要做的是，在微调器中放置一个键值。因此，当我的btn_getReport按钮被点击时，我得到所选项目的值。就像如果All被选中，那么我得到 0 等等。这个关键价值的东西正在起作用。问题是当btn_getReport获得点击时，我怎样才能获得所选项目的值。因为我在后台线程中填充项目（在 OrgaLevelTask 和 SubOrgaLevelTask 中）并且我的按钮在 Activity 中。那么当按钮被点击时我该怎么做，然后我从 OrgaLevelTask 和 SubOrgaLevelTask 中定义的地图中获取值？
谢谢
