    Either add this as scrollbar's XML attribute

    android:isScrollContainer="false"

    or add this in Activity's tag in Manifest

    android:windowSoftInputMode="adjustPan"

    Just add this line in your onCreate, When this option set the window not adjust for a shown input method. :

    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING);

    I've come across a pretty similar problem with the differences that a) I wasn't using a ScrollView at first and b) the item I didn't want to move was a simple TextView.

    Here's the answer I found: click

    What I did to fix it:

    • Use adjustResize
    • Use 4 Layouts: A surrounding one, 1 for the header, the ScrollView and 1 for your "bottom nav"
    • Don't just rely on android:layout_alignParentBottom="true", while this will move your navigation bar to the bottom of the screen, it also means that the keyboard can move it up because of "adjustResize"
    • Additionally use android:layout_height="wrap_content" in combination with android:layout_below="@id/MyScrollView" (so the layout will use up all the space it can get between the ScrollView and the bottom of the screen) and android:gravity="bottom" to simply have everything at the bottom of the layout.
    • You might also be able to use android:layout_height="match_parent" instead of android:layout_alignParentBottom="true" and android:layout_height="wrap_content" but I didn't fully test it like that.
    • Like I said, this will make the "bottom nav" layout use up all the space it can get below the ScrollView. If you don't want that, e.g. because your "bottom nav" has a different color you don't want to be shown too much, try creating a surrounding RelativeLayout for "bottom nav" and another empty layout inside that can push "bottom nav" downwards. ;)

    I am very late to answer but I ran into same situation lately. I followed another approach to solve this issue and that was rather than using RelativeLayout or LinearLayout, using CoordinatorLayout and having behavior applied to BottomNavigtaionView to show/hide it with scrolling to top or bottom (the same way we see CollapsingToolBar or AppBarLayout).

    The built in behavior used for BottomNavigationView is app:layout_behavior="@string/hide_bottom_view_on_scroll_behavior"

    You can read all steps in detail from my another answer here.

    P.S. I posted it as an answer rather than a comment because sometimes we just look for answers and ignore the comments and I believe it could be a good approach to solve this issue, so you should not ignore it and give it a read once. Thanks.

    I tried a lot of solutions found on SO and only adding android:windowSoftInputMode="adjustNothing" into the manifest for the activity worked for me:

    <activity
        android:name=".MainActivity"
        android:windowSoftInputMode="adjustNothing">
    

    Associated layout:

      <RelativeLayout
         ...
            <android.support.v4.widget.NestedScrollView
               ...
            </android.support.v4.widget.NestedScrollView>
            <android.support.design.widget.BottomNavigationView
                 ...
                design:menu="@menu/navigation"/>
        </RelativeLayout>
