如何执行后台作业更新UI的Andr​​oid观点 [英] How to execute background job that update UI view Android

问题描述

在我的Andr​​oid应用程序，我有一个活动有意见。

In my Android application I have an activity with views.

要在活动开始或创造主要布局例如，我想启动去更新从主要布局为每5秒一个UI视图后台作业。

To the beginning of the activity or to the creation of main layout for example, I would like to start a background job that goes to update UI view from main layout for each 5 seconds.

所以，我对当下的策略是通过我的课，从观派生的runOnUiThread方法创作的主要布局过程中创造了Runnable。

So, my strategy for the moment was to create Runnable during creation of the main layout by using runOnUiThread method of my class that derives from View.

线程正常启动，但在线程我愿做一个等待5秒钟之前更新UI视图再次等待。我的问题是，当我使用视频下载，用户界面​​被阻止。

The thread starts correctly but in the thread I would like to do a wait for 5 seconds to wait before update UI view again. My problem is when I use Thread.sleep, the UI is blocked.

我猜Thread.sleep（）方法阻止整个UI，但我不知道我该怎么做，必须解决这个问题。

I guess Thread.sleep() blocks the entire UI but I don't know how I must make to solve that problem.

所以我的问题是：什么是实现我想要的最好的解决方法（不使用的睡眠也许）

So my question is the following : what is the best solution to realize what I want (without using sleep perhaps) ?
