I am trying to hide my tool bar when I scroll my text and image with content. Here I use scrollView for getting scroll content. When I scroll content up, how to hide the tool bar?
Here is my XMl code:
content_main.XML:
<android.support.v4.widget.NestedScrollView

android:layout_width="match_parent"
android:layout_height="match_parent"

app:layout_behavior="@string/appbar_scrolling_view_behavior">

android:layout_marginRight="10dp"

android:textStyle="bold"
android:text="hello world jheds sdjhs jds sjbs skjs ksjs kksjs ksj sdd dskd js sk "/>
<ImageView
android:id="@+id/imge"
android:layout_width="match_parent"
android:layout_height="250dp"
android:src="@drawable/imag_bg"/>
<TextView
android:id="@+id/texttwo"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:text="Pretty good, the Toolbar is moving along with the list and getting back just as we expect it to. This is thanks to the restrictions that we put on the mToolbarOffset variable.
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
