如何显示的图3秒钟，然后将其隐藏？ [英] How to show a view for 3 seconds, and then hide it?

问题描述

我试图与线程，但是Android抛出CalledFromWrongThreadException：只有创建视图层次可以触摸其观点原来的线程。

I tried with threads, but android throws "CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.".

所以，我怎么能等待3秒，然后隐藏视图，让图形界面响应？

So how can I wait 3 seconds and then hide the view, letting the GUI responsive?

一个定时器使用另一个线程要么，所以它不会解决。

A Timer uses another thread either, so it will not solve..

推荐答案

产卵的睡3秒一个单独的线程然后调用runOnUiThread隐藏的看法。

Spawn a separate thread that sleeps for 3 seconds then call runOnUiThread to hide the view.

Thread thread = new Thread() {
    @Override
    public void run() {
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
        }

        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                // Do some stuff
            }
        });
    }
};
