Android View.setKeepScreenOn() - does it apply when the view is GONE?

Question

I have a View with some GPS info. It is made VISIBLE/GONE with a GPS on/off switch inside the app. I want to call setKeepScreenOn(true) on this view so that it keeps screen on but ONLY when it is VISIBLE and NOT when it is GONE.

Answer 1

I would say it also applies when the view is gone, but I don't know. It shouldn't be hard to test though.

But you can just use View.setKeepScreenOn(false) whenever you're setting its visibility to GONE and View.setKeepScreenOn(true) whenever you're setting its visibility to VISIBLE.

View view = ...; // I guess something with findViewById() happens here
view.setVisibility(View.GONE);
view.setKeepScreenOn(false);
...
view.setVisibility(View.VISIBLE);
view.setKeepScreenOn(true);

Or that you don't have to keep that in mind, you could define a method for that:

private void mySetVisibility(View v, int visibility) {
    v.setVisibility(visibility);
    if (visibility == View.GONE) {
        v.setKeepScreenOn(false);
    } else {
        v.setKeepScreenOn(true);
    }
}

and then just use mySetVisibility(view, View.GONE) and mySetVisibility(view, View.VISIBLE).

Pretty straightforward.

Hope it helps.
