In a vertical LinearLayout I have two views. Depending on user actions, I wish to hide the lower view, and have the upper view take up the newly empty space. Hiding and showing the lower view is no problem via addView/removeView, but that doesn't cause the upper view to take up the empty space. Calling requestLayout() and forceLayout() on the parent layout has no effect; what is the magic incantation for a dynamic re-layout?
I'm still stuck on this. I've tried many combinations of setVisibility(View.GONE), parent.removeView, setMinimumHeight, invalidate, parent.requestLayout() and parent.forceLayout() - the result is alway the same: the bottom view is hidden/gone, but the top view will not take expand to take its place.
What's strange is that there are many posts out on the net where one or the other of the method calls I mentioned are said to achieve this effect; but not on my device, and not on any Android version on the emulator.
The following is the layout I'm using; I want to make the "buttons" LinearLayout disappear under certain circumstances (namely, if a soft keyboard is shown):
(Yes, I know I could be using a RelativeLayout, but that doesn't help with the problem at hand.)
In the end, I did not get this to work, so I resorted to using 2 different layouts - one with, and one without the buttons. The functionality of the buttons will be provided by the options menu instead.
A strange and disappointing case - everything and everybody says this should work, but I can't there from here.
