android - View getVisibility() isShown() return incorrect visibility

I've a view that gets conditionally added to parent. I check if its already added to parent or not, unfortunately, it always return its visible.

if (findViewById(R.id.bottom_bar).getVisibility == View.Visible)

if (findViewById(R.id.bottom_bar).isShown()) 

both return true even when view was never added ans is not visible.

See Question&Answers more detail:os

getVisibility() simply returns the visibility you want the view to have when added to the window. It doesn't change unless you call setVisibility(). It also doesn't indicate whether the view is actually visible on screen.

isShown() is similar. Here is the doc:

Returns the visibility of this view and all of its ancestors

Returns
True if this view and all of its ancestors are VISIBLE
