我怎样才能刷新活动？ [英] How can I refresh the activity?

问题描述

我要刷新的活动，因为我想thatwithout烧制一些工作得到执行和活动本身要求的任何事件。所以，我想知道的是有Android中的任何选项本身刷新活动。

I want to refresh the activity as i want thatwithout firing any event some work gets performed and activity calls by itself. So, i want to know is there any option in android to refresh the activity by itself.

推荐答案

您可以自己通过在其上调用postDelayed（..）处理程序做到这一点。

You can do this by yourself through a Handler on which you call postDelayed(..)

的http://developer.android.com/reference/android/os/Handler.html#postDelayed(java.lang.Runnable,长）

将这个：

private final Handler handler = new Handler();

进行调用的函数：doTheAutoRefresh（），做：

make a function called: doTheAutoRefresh() that does:

private void doTheAutoRefresh() {
    handler.postDelayed(new Runnable() {
             @Override
             public void run() {
                 doRefreshingStuff(); // this is where you put your refresh code
                 doTheAutoRefresh();                
             }
         }, 1000);
}

调用此函数在你的onCreate。

Call this function in your onCreate.

请注意：这是基本的做法。考虑停止在此之后的onPause已经调用了onResume后恢复它。看看处理程序类，看看如何删除。

NOTE: this is the basic approach. consider stopping this after onPause has been called and to resume it after onResume. Look at the handler class to see how to remove.
