    I am not using listview, only scrollview and inside linearLayout

    Ah thats right.

    view.ScrollTo(0, view.Bottom);

    It should work, however you must do it from the UI thread. So in some cases you need to wrap it in RunOnUiThread()

    view.Bottom always return 0 even there is items, and the scroll apear

    Where exactly do you do this? In what part of your code?

  • nahumgliknahumglik ILMember ✭

    in onResume

        private void scrollDownScrollView()
    {
        ScrollView sv = (ScrollView)FindViewById(Resource.Id.scroll);

        RunOnUiThread(() =>
        {                
            sv.Post(new Java.Lang.Runnable(aa) );                
        });            
    }

    private void aa()
    {
        ScrollView sv = (ScrollView)FindViewById(Resource.Id.scroll);
        sv.FullScroll(FocusSearchDirection.Down);
    }

    I have this working, i.e.
    protected void ScrollToBottom()
    {
    ScrollView sv = (ScrollView)FindViewById (Resource.Id.scrollView1);
    RunOnUiThread(() =>
    {
    sv.Post(new Java.Lang.Runnable(scrollit));
    });
    }

            private void scrollit()
        {
            ScrollView sv = (ScrollView)FindViewById<ScrollView> (Resource.Id.scrollView1);
            sv.FullScroll(FocusSearchDirection.Down);
        }

    But ideally, I would like just to have one method and not hard code the ScrollView resource. How can I pass data to scrollit?

    Can anyone tell me how to do this with a nested scrollview?
    When i put sv.FullScroll(FocusSearchDirection.Down);
    it says it cannot convert focussearchdirection.Down to int.

    Any help would be greatly appreciated
