如何在Android 4.0+上禁用主页，电源和搜索按钮？

Answer 1

You can hide them using SYSTEM_UI_FLAG_HIDE_NAVIGATION :

myView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);

This property is only in 4.0+. The closest 3.0+ gets is SYSTEM_UI_FLAG_LOW_PROFILE .

But they should not (if they even can) be permanently disabled; imagine how you'd feel if an app took away your ability to use the "home" button, then started an infinite loop.

Edit : Wait, just read "Home, Power, and Search" buttons. You can't disable the power button (that would be silly), and most Android 4.0 phones don't have a dedicated search button unless they are upgrades of 2.3 devices (Galaxy S II, for example). My above info covers the soft Home, Back, and Recent Apps keys.
