Android 使用volley过程中遇到的问题解决办法

private void getWxpayOrderInfo() { StringRequest stringRequest = new StringRequest(Request.Method.POST, Url, new Response.Listener<String>() {  @Override  public void onResponse(String response) {  } }, new Response.ErrorListener() {  @Override  public void onErrorResponse(VolleyError error) {  } }) {  @Override  protected Map<String, String> getParams()  throws AuthFailureError {   // 发送请求用到的一些参数   Map<String, String> params = new HashMap<String, String>();   params.put("id", "nameid");   return params;  } }; stringRequest.setRetryPolicy(new DefaultRetryPolicy(10000,                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT)); queue.add(stringRequest); //queue.start(); //经过反复调试错误就出在这里，注释掉这里就可以了}
