运行$ C $在主线程从另一个线程C- [英] Running code in main thread from another thread

问题描述

在一个机器人服务，我已经创建的线程（S）做一些后台任务。

In an android service I have created thread(s) for doing some background task.

我有一种情况，该线程需要张贴在主线程的消息阙某项任务，例如可运行。

I have a situation where the thread need to post certain task on main thread's message que, for example a runnable.

有没有办法让主线程和后消息处理程序/可运行它从我的其他线程？

Is there a way to get Handler of the main thread and post message/runnable to it from my other thread ?

谢谢

推荐答案

请确保您的后台工作线程可以访问一个Context对象（可以是应用程序上下文或服务上下文）。然后，只需为此在后台工作线程：

Make sure that your background worker threads have access to a Context object (can be the Application context or the Service context). Then just do this in the background worker thread:

// Get a handler that can be used to post to the main thread
Handler mainHandler = new Handler(context.getMainLooper());

Runnable myRunnable = new Runnable() {
    @Override 
    public void run() {....} // This is your code
};
mainHandler.post(myRunnable);
