Android 启动画面/加载画面
我有一个启动屏幕/加载屏幕，在我的大位图的绘制调用完成后，.setVisibility() 立即消失。问题是启动屏幕需要一点时间才能弹出，我相信这是由于主要活动启动并在第一次运行时执行 CPU 密集型应用程序所致。有没有办法让我的启动画面尽快显示？如果我把它放在不同的线程中可以吗？初始屏幕只是一个位图，其下方有一个进度条。我的布局是基于 xml 的，所以我看不到自己使用 setContentView。谢谢。
I have a splash screen/loading screen that has .setVisibility() to GONE right after the draw call of my large bitmap is completed. The problem is the splash screen takes a bit to popup which i believe is due to the main activity booting up and doing CPU intensive applications on first run. Is there a way to get my splash screen displayed ASAP? Would it be ok if i had it in a different thread maybe? The splash screen is just a bitmap with a progressBar right below it. My layout is xml based so i cant see myself using setContentView. Thanks.

在android中，当我们构建一个应用程序时，我们可能需要显示一个启动屏幕（欢迎屏幕），以便用户提示一些事情和信息。在后台执行一些
其他进程（例如从数据库获取数据、解析XML等），因此最好在不同的线程中实现它。我已经在 www.androidpeople.com 网站上引用了 SPLASH SCREEN 的示例，您也可以看看这个启动屏幕示例。
In android, when we build an application we may need to display a splash screen ( welcome screen ) for users to intimate some thing & do some
other process in background( like fetching data from DB, Parsing XML , etc.. ), so for that it is preferrable to implement it in a different thread.I have referred the example on www.androidpeople.com site for the SPLASH SCREEN, you may also Have a look at this example of SPLASH SCREEN .
您希望有一个单独的线程在后台执行任务，同时在前台显示进度并在执行此操作后调用您所说的 setVisibility(...) 方法。
我遇到过这个教程： http:// /www.41post.com/4588/programming/android-coding-a-loading-screen-part-1
我发现它非常好，很容易实现，只需一堂课，在第 2 部分之后您将了解如何真正彻底摆脱 AsyncTask (http://stackoverflow.com/questions/3077461/asynctask-threads-never-die-android)。
You want a separate thread to execute tasks in background, while showing progress in the foreground and call the setVisibility(...) method you say after doing so.
I've come across this tutorial: http://www.41post.com/4588/programming/android-coding-a-loading-screen-part-1
I've found it excellent, it's easy to implement, only one class and after part 2 you learn how to really get rid of the AsyncTask definitevely (http://stackoverflow.com/questions/3077461/asynctask-threads-never-die-android).
您可以尝试将启动画面设置为您的活动的主题
You can try setting the Splashscreen as a theme to your activity
