我有两个片段活动，即Feed和Profile.Both这些活动使用一个排球JSON请求从服务器请求一些数据。我还创建了一个封装Volley RequestQueue的单例类。最初，两个活动都使用齐射正确加载数据。但是，在活动之间连续切换后，Volley会抛出以下错误，之后在一段时间内没有向服务器发送任何请求。

等待一段时间后，当我再次在活动之间切换时，凌空正确加载数据。我在StackOverflow上阅读了很多问题但是它们似乎都没有解决我的问题。这就是我的截击请求：
{
Map<String, String> params = new HashMap<String, String>();
params.put(UID, String.valueOf(Singelton.getUserID()));
params.put(COUNT,Integer.toString(cnt));
RequestQueue requestQueue = CustomVolleyRequest.getInstance(getActivity().getApplicationContext()).getRequestQueue();
CustomRequest jsObjRequest = new CustomRequest(Request.Method.POST, url, params, new Response.Listener<JSONObject>()
{
@Override
public void onResponse(JSONObject response)
{
Log.d("respnse:",response.toString());
processresponse(response);
}
}, new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error)
{
error.printStackTrace();
}
});
requestQueue.add(jsObjRequest);
}
