How to detect full screen gesture mode in android Q

问题

In Android Q, users can enable full screen gesture mode. I want to detect whether the device in full screen gesture mode or not. I can't find anything in documentation. How to do it programmatically at run time?

Java or kotlin language answer is OK.

Any official API or workaround...

回答1:

According to docs, you can get area of gesture space using getSystemGestureInsets(): https://developer.android.com/reference/android/view/WindowInsets.html#getSystemGestureInsets()

If it's zero, then it's disabled

    ViewCompat.setOnApplyWindowInsetsListener(view, (v, insets) -> {
        if (insets.getSystemGestureInsets().bottom == 0 
            && insets.getSystemGestureInsets().left == 0
            && insets.getSystemGestureInsets().right == 0) 
        {
            //gestures enabled
        }
        return insets.consumeSystemWindowInsets();
    });

However, I don't have device with Android Q, and I might be wrong

I've found it in this article: https://developer.android.com/preview/features/gesturalnav
