我是pretty的肯定幼儿锁只使用一个BroadcastReciever并侦听 Intent.ACTION_MAIN 而类别 Intent.CATEGORY_HOME - 这就是为什么当你第一次启动它，它会告诉你，检查使用默认应用程序对话框，让你选择蹒跚学步的锁。

I'm pretty sure Toddler Lock just uses a BroadcastReciever and listens for Intent.ACTION_MAIN and the category Intent.CATEGORY_HOME - that's why when you first launch it, it tells you to check the "use this application as default" box, and makes you select toddler lock.

因此​​，它不是真正阻止Home键的话，那只是自己设定为默认的广播接收器：

So, it's not really blocking the Home button at all, it's just setting itself up as the default broadcast receiver for:

Intent i = new Intent(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME);

当您启动幼儿锁，它可能设置一个内部标志，如果你preSS home键，它只是将窗口的前面。如果标志没有设置，它可能明确地启动启动。

When you launch Toddler Lock, it probably sets an internal flag, and if you press the home button, it just brings the window to the front. If the flag is not set, it probably launches Launcher explicitly.

我希望这是有道理的。这只是一个理论，但我几乎可以100％肯定这是它是如何做的。

I hope that makes sense. It's just a theory, but I'm almost 100% sure that's how it's done.
