Wie man ToolBar versteckt, wenn ich Inhalt in Android nach oben scrolle
Ich versuche, meine Symbolleiste auszublenden, wenn ich durch Text und Bild scrolle. Hier verwende ich scrollView, um den Inhalt zu scrollen, wenn ich nach oben scrolle, um die Symbolleiste auszublende
hier mein XMl Code

If we would omit checking if it’s bigger than 0 and lower than mToolbarHeight then when
we would scroll
up our list, the Toolbar would move along far away off the screen, so to show it back you
would have to scroll the list down to 0. Right now it just scrolls up to mToolbarHeight
position and not more so it’s “sitting” right above the list all of the time and if we
start scrolling down, we can see it immediately showing.

It works pretty well, but this is not what we want. It feels weird that you can
stop it in the middle of
the
scroll and the Toolbar will stay half visible. Actually this is how it’s done in Google Play
Games app
which I consider as a bug
