java - 如何将异步任务的输出设置为主 Activity 的 TextView

Question

public class  CheckLoginCredentialsTask extends AsyncTask<Boolean, Integer, 
EEmployeeHTTPResponse> {

MainActivity obj = new MainActivity();
private ProgressDialog ResponseProgress;
private Activity curActivity;
String employeeId,password;
String IMEI_Number = "";

public void setContextandActivity(Activity activity,String id,String pwd) {
    this.curActivity=activity;
    this.employeeId=id;
    this.password=pwd;
}

@SuppressLint("LongLogTag")
protected EEmployeeHTTPResponse doInBackground(Boolean... param) {
    try {
        HTTPCommunication loginHTTPRequest;
        if (employeeId != null) {
            Log.i("eEmp/CheckLoginTask", "doInBackg");
            loginHTTPRequest = new HTTPCommunication();
            EmployeeInfoDTO loginInfo = new EmployeeInfoDTO();
            Boolean Profile_Required_Status = param[0];
            loginHTTPRequest.setRequestType(EmpConstants.HTTPRequestType.NewUser);

            if (Profile_Required_Status) {  // Profile_Required_Status = Yes
                loginInfo.Profile_Required = EmpConstants.Profile_Required_Yes;
            }
            loginInfo.EMPID = employeeId;
            loginInfo.Password = password;
            return loginHTTPRequest.SendHTTPRequest(loginInfo);
        }
        return null;
    } catch (Exception e) {
        Log.d("eEmp/CheckLogin/Error", e.toString());
        return null;
    }
}

protected void onProgressUpdate(Integer... progress) {
    Log.d("eEmp/ChkLoginTskProg", "onProgress");
}

protected void onPostExecute(EEmployeeHTTPResponse result) {
    String toastStr = "";

    try {
        if (result != null) {
            if (result.HTTPStatusCode == 200) {
                if (result.Data != null) {
                    if (result.Data.ResponseCode == ActionStatus.Codes.UserFound) {
                        EmployeeInfoResponseDTO empDetails = (EmployeeInfoResponseDTO) result.Data.ActionResult;
                        if (empDetails != null) {
                            obj.tvEmpId.setText(empDetails.EmpID);
                            obj.tvType.setText(empDetails.EmpType);
                            obj.tvDept_code.setText(empDetails.DEPT_CODE);
                        }
                    }
                }
            }
        }
        Log.d("eEmp/CheckLoginTsk", "onPostExecute");
    } catch (Exception e) {
        Log.d("eEmp/PostExecute", e.toString());
    }
}
}

我从服务器得到的结果在 onPostExecute 方法的 empDetails 中。在 empDetails 中有 3 个字段 EmpID、EmpType、EmpDept。现在我需要将这些值设置到 MainActivity 中的 textviews。

我为 MainActivity 创建了对象，然后我调用了 obj.textview 但是它没有从 MainActivity< 访问 textview/.

如何在这里访问 textview。或者如果有任何其他方法存在，请告诉我。

如有任何帮助，我们将不胜感激。

尝试将所有 textviews 设置为 public static 并使用 MainActivity.obj.setText(""); 直接从此类访问它
