Question

我正在使用android-async-http，并覆盖所有onSuccess和onFailure方法，但我收到了错误消息： onSuccess(int, Header[], JSONObject) was not overriden, but callback was received。

cz.msebera.android.httpclient.client.HttpResponseException: Not Found

我只是想知道我真的覆盖了这个方法。我也得到了日志：onSuccess JSONObject:{"error":null,"success":false}

  public static void querySecurityCode(String username) {
        RequestParams params = new RequestParams();
        params.put("username", username);
        VStarRestClient.getClient().setEnableRedirects(true);
        VStarRestClient.post(GET_SECURITY_CODE_URL, params, new JsonHttpResponseHandler(){
            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                super.onSuccess(statusCode, headers, response);
                Log.i("ws", "---->>onSuccess JSONObject:" + response);
            }

            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
                super.onSuccess(statusCode, headers, response);
                Log.i("ws", "---->>onSuccess JSONArray");
            }

            @Override
            public void onSuccess(int statusCode, Header[] headers, String responseString) {
                super.onSuccess(statusCode, headers, responseString);
                Log.i("ws", "---->>onSuccess responseString");
            }


            @Override
            public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
                super.onFailure(statusCode, headers, responseString, throwable);
                Log.i("ws", "---->>onFailure:" + throwable.toString());
            }

            @Override
            public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
                super.onFailure(statusCode, headers, throwable, errorResponse);
                Log.i("ws", "---->>onFailure" + throwable.toString());
            }

            @Override
            public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONArray errorResponse) {
                super.onFailure(statusCode, headers, throwable, errorResponse);
                Log.i("ws", "---->>onFailure" + throwable.toString());
            }


        } );
    }

Answer 1

你不应该致电super.onFailure和super.onSuccess，当你没有覆盖它们时，警告来自超级方法。

Answer 2

我遇到了同样的问题。我的Rest API返回JSONObjects的数组，即JSONArray。但是我的代码尝试在JSONObjects中进行收集。

解决方案：下面的代码对我来说很好。 JsonHttpResponseHandler的Override方法

public void onSuccess（int statusCode，Header []标头， JSONArray响应 ）{ }

而不是使用以下方法覆盖，该方法会导致错误： public void onSuccess（int statusCode，Header []标头， JSONObject响应）{ }

Answer 3

试试这一行

public void onSuccess(int statusCode, Header[] headers, JSONObject response) {

System.out.println("Received event with data: " + response);
}

Answer 4

JsonHttpResponseHandler 有2种OnFailure覆盖方法。尝试另一个

onSuccess（int，Header []，JSONObject）未被覆盖，但收到了回调
