Question

我创建活动时创建HashMap<String, Boolean> ... hashmap包含：

{email=false, username=false, password=false, firmcode=false}

成功响应后，我从onResponse回调中的Retrofit调用中获取我将hashmap的密码键值更新为true

inputValidityMap.put(getResources().getString(R.string.password_tag), true);

问题是当我记录hashmap时，密码密钥的值还没有更新

if (connectivityObserver.getConnectivityStatus(getActivity()) != AppConfig.NO_CONNECTION) {
     Call<UserConnectionStaff> call = apiService.isPasswordValid(getResources().getString(R.string.passwordValidation), registerPasswordEdt.getText().toString());
     call.enqueue(new Callback<UserConnectionStaff>() {
           @Override
           public void onResponse(Response<UserConnectionStaff> response, Retrofit retrofit) {
              int resource_message = inputValidationCodes.get(response.body().getError_code());
              if (isAdded()) {
                 if (response.body().getError_code() != AppConfig.INPUT_OK) {
                    if (response.body().getError_code() == AppConfig.ERROR_INVALID_INPUT) {
                        passwordErrorTtv.setText(commonElements.decodeUtf8(commonElements.encodeUtf8(getResources().getString(resource_message))));
                    } else 
                        passwordErrorTtv.setText(commonElements.decodeUtf8(commonElements.encodeUtf8(getResources().getString(resource_message))));
                    }
                } else {
                    animationStaff(acceptPasswordRlt, 0.0f, 1.0f, "visible");
                    animationStaff(showHidePasswordTtv, 1.0f, 0.0f, "gone");
                    Log.d(debugTag, inputValidityMap.containsKey(getResources().getString(R.string.password_tag)) + "");
                    inputValidityMap.put(getResources().getString(R.string.password_tag), true);
                }
             }
          }

          @Override
          public void onFailure(Throwable t) {
             if (isAdded()) {
                if (t instanceof IOException) {
                     setToastHelperMsg(getResources().getString(R.string.unavailable_service));
                } else {
                     setToastHelperMsg(getResources().getString(R.string.error_occured));
                }
                registerUsernameEdt.setText(null);
                progressViewActions("stop", usernameProgressView);
             }
          }
     });
} else {
     if ( isAdded() )
          setToastHelperMsg(getResources().getString(R.string.no_connection));
}
Log.d(debugTag, inputValidityMap.toString());

Answer 1

我认为问题在于

 **Log.d(debugTag, inputValidityMap.toString());**

在onResponse或onFailure事件之外。 onResponse和onFailure将以异步方式执行，并且可能在您到达代码的最后一行（即日志行）之前不会执行。

在onResponse方法上修改哈希映射后，尝试添加完全相同的日志行。您应首先看到值仍为false的最后一行上的日志，稍后您将看到执行onResponse方法后追逐到true的值。

最后我发现了什么是错的... @ user1880062是绝对的怀疑...... onResponse回调是异步执行的...所以我已经做了一个简单的方法..我创建了一个接口，当onResponse被执行时我打电话它的方法具有所需的布尔值我想更新hashmap的值...所以我得到了callcack之外的值，实现了包含tha方法的接口，我在回调中更改了布尔值...

hashmap布尔值未更新
