解决方法:

您可以尝试以下方法：

创建自己的自定义接口以获取回调：

import org.Json.JsONObject;/** * Implement this Listener for getting callback for UploadManager.doUpload() * method. *  *  */public interface UploadListener {    /**     * On success upload, server response for given network upload task.     *      * @param response     */    voID onSuccessuploadResponse(JsONObject response);    /**     * On Failed upload, server response for given network upload task.     *      * @param error     */    voID one rrorUploadResponse(Throwable error);}

比为网络 *** 作创建一个Singleton类并抽象出凌空代码：

import org.Json.JsONObject;import androID.content.Context;import androID.util.Log;import com.androID.volley.Request;import com.androID.volley.RequestQueue;import com.androID.volley.Response;import com.androID.volley.VolleyError;import com.androID.volley.toolBox.JsonObjectRequest;import com.androID.volley.toolBox.Volley;/** * Singleton class for network operations and to abstract out the volley * code. *  * @see <a *      href=" http://developer.androID.com/training/volley/index.HTML">Volley</a> *  *  */public class UploadManager {    private static UploadManager uploadManager;    private static RequestQueue mRequestQueue;    public static final int METHOD_POST = Request.Method.POST;    public static final int METHOD_GET = Request.Method.GET;    public static final int METHOD_PUT = Request.Method.PUT;    public static final int METHOD_DELETE = Request.Method.DELETE;    private UploadManager(Context context) {        mRequestQueue = Volley.newRequestQueue(context);        // Start the queue        mRequestQueue.start();    }    public static UploadManager getinstance(Context context) {        if (uploadManager == null) {            uploadManager = new UploadManager(context);        }        return uploadManager;    }    /**     * Implement UploadManager.CallbackListener for getting callback for this     * method.     *      * @param url     *            : url to be used for network call.     * @param method     *            : http method type.     * @param JsonRequest     *            : JsON object to be sent     * @param callbackListener     *            : callback Listener for getting success or error callback.     */    public voID doUpload(String url, int method, JsONObject JsonRequest,            final UploadListener callbackListener) {        JsonObjectRequest JsObjRequest = new JsonObjectRequest(method, url,                JsonRequest, new Response.Listener<JsONObject>() {                    public voID onResponse(JsONObject response) {                        callbackListener.onSuccessuploadResponse(response);                    };                }, new Response.ErrorListener() {                    @OverrIDe                    public voID one rrorResponse(VolleyError error) {                        if (null != error) {                            callbackListener.onErrorUploadResponse(error                                    .getCause());                        }                    }                });        mRequestQueue.add(JsObjRequest);    }}

您可以使用doUpload();您所有类中的方法,而无需一次又一次地编写volley代码.
