下面是一个方法,我试图通过调用getSelf()来检索用户对象.问题是结果始终为null,因为Volley请求在返回结果时尚未完成.我对异步进程有些新意,所以我不确定让方法等待API调用结果返回UserBean对象的最佳方法.谁能给我一些帮助?
public UserBean getSelf(String url){
RpcJSONObject jsonRequest = new RpcJSONObject("getSelf", new JSONArray());
JsonObjectRequest userRequest = new JsonObjectRequest(Request.Method.POST, url, jsonRequest,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
String result;
try {
result = response.getString("result");
Gson gson = new Gson();
java.lang.reflect.Type listType = new TypeToken<UserBean>() {}.getType();
//HOW DO I RETURN THIS VALUE VIA THE PARENT METHOD??
userBean = (UserBean) gson.fromJson(result, listType);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
