在非rooted 4.0+ android平板电脑上以编程方式禁用（不隐藏）系统UI栏？

Question

In my app, there is a activity where it is important that the system UI buttons (home, back, etc.) are not pressed, though it is ok if they are still visible. I have heard that there might be a way to achieve this, at least in 4.0 (I'm using 4.2).

A way to quickly and automatically return to the app if the buttons are pressed is also a correct answer, but seems less plausible. Thanks.

Answer 1

This is possible to override the home button by making your activity as home activity ie -- category android:name="android.intent.category.HOME"

but in this case android give user option to choose the app on launcher dialog where if user choose your application and click always, he will not be able to go to homescreen until you specifically provide a exit button oinside your app and reset it which you should definately do.
