如何在Java的Andr​​oid上执行一个功能每两秒钟？ [英] How to execute a function every two seconds in Java on Android?

问题描述

我想在我每两秒钟Android程序执行的Java的code一大块。我的code目前看起来是这样的：

I'm trying to execute a chunk of Java code in my Android program every two seconds. My code currently looks like this:

       LinearLayout.postDelayed(new Runnable() { 
            public void run() { 

            //Do stuff here

            } 
       }, 2000);

不幸的是，两秒钟后该只运行一次，然后再也没有运行。我怎么能得到它运行每两秒钟？

Unfortunately, this only runs once after two seconds and then never runs again. How could I get it to run every two seconds?

在此先感谢您的帮助。

推荐答案

试试这个：

   LinearLayout.postDelayed(new Runnable() { 
        public void run() { 

        //Do stuff here

            // assuming LinearLayout is enclosing class
            LinearLayout.this.postDelayed(this, 2000);
        } 
   }, 2000);
