您能告诉我为什么我无法点击onCreate() { ... getNewsItems(new NewsItemsListener() { void onFetched(ArrayList<NewsItems> items) { // Do whatever you want to do with your news items } }); } public void getNewsItems(final NewsItemsListener listener) new AsyncTask<Void, Void, ArrayList<NewsItems>>() { @Override protected ArrayList<NewsItems> doInBackground(Void... params) { ArrayList<NewsItems> response = whatEverMethodGetsMeNetworkCallResponse(); return response; } @Override protected void onPostExecute(ArrayList<NewsItems> response) { super.onPostExecute(response); listener.onFetched(response); } }.execute(); } public interface NewsItemsListener { void onFetched(ArrayList<NewsItems> items); }

来增加这一天的时间

  var dayLength = 1000*3600*24;
  var current = new Date();
  console.log(current);
  $('button').on('click', function(){
    var a = new Date((new Date()).valueOf() + dayLength);
    console.log(a);
   });

Answer 1

您将dayLength添加到new Date()这是当前日期。您应该将其添加到current变量。

  var dayLength = 1000*3600*24;
  var current = new Date();
  console.log(current);

  $('button').on('click', function(){
    current = new Date(current.getTime() + dayLength);
    console.log(current);
   });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="btn btn-default">+</button>

请注意，我还将valueOf更改为getTime，因为每docs，通常不会在用户代码中调用valueOf。

无法在Js日期库中增加日期
