Question

我试图将此代码https://github.com/smanikandan14/Volley-demo/blob/master/volleydemoapp/src/main/java/com/mani/volleydemo/JSONObjectRequestActvity.java改编为我自己的项目。

当我尝试制作JSONObjectResponse

时

jsonObjRequest = new JsonObjectRequest(Request.Method.GET, builder.toString(), null, new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            try {
                parseFlickrImageResponse(response);
                mAdapter.notifyDataSetChanged();
            } catch (Exception e) {
                e.printStackTrace();
                showToast("JSON parse error");
            }
            stopProgress();
        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            // Handle your error types accordingly.For Timeout & No connection error, you can show 'retry' button.
            // For AuthFailure, you can re login with user credentials.
            // For ClientError, 400 & 401, Errors happening on client side when sending api request.
            // In this case you can check how client is forming the api and debug accordingly.
            // For ServerError 5xx, you can do retry or handle accordingly.
            if( error instanceof NetworkError) {
            } else if( error instanceof ClientError) {
            } else if( error instanceof ServerError) {
            } else if( error instanceof AuthFailureError) {
            } else if( error instanceof ParseError) {
            } else if( error instanceof NoConnectionError) {
            } else if( error instanceof TimeoutError) {
            }

            stopProgress();
            showToast(error.getMessage());
        }
    });

但是出现了这个错误：

Cannot resolve symbol 'ClientError'

我试图以多种方式输入截击，但它们似乎都没有效果。（.jar，compile＆＃39; com.android.volley：volley：1.0.0＆＃39 ;, compile＆＃39; com.mcxiaoke.volley：library：1.0.19＆＃39;等）。

顺便说一下，我使用的是Android Studio。
