我认为这个错误与我没有在一个线程中运行我的JSON这一事实有关。以下是我的代码如何解决这个问题？我是否需要将其置于可运行状态，如果是这样，我该怎么做？我对线程的概念比较新，所以请帮助我吗？
private void JsonRequestMethod() {
mVolleySingleton = VolleySingleton.getInstance();
//intitalize Volley Singleton request key
mRequestQueue = mVolleySingleton.getRequestQueue();
//2 types of requests an Array request and an Object Request
JsonArrayRequest request = new JsonArrayRequest(Request.Method.GET, URL_API, (String) null, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
listblogs.clear(); // here you clear the old data
listblogs=parseJSONResponse(response);
mAdapterDashBoard.setBloglist(listblogs);
System.out.println("it worked!!!");
}

@Override
