如何停止列表视图上的滚动动画？

Question

Is it possible to stop a ListView from scrolling? I currently have a ListView with a margin on top to show an image view that will sit behind there. My goal is to cover the ImageView that will sit behind the ListView when the person is scrolling up, as the ListView is scrolls up it will also close the margin it has eventually hiding the ImageView that sits behind it. I currently have it doing just that but I'm trying to figure out how to stop the scrolling animation on the ListView till the ListView closes it's margin. ('mainItemDisplayer' is the ListView .)

public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {

            //mainItemDisplayer.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_CANCEL, 0, 0, 0));
            int scrolledOffset = mainItemDisplayer.getVerticalScrollOffset();

            if (scrolledOffset!=mainItemDisplayer.mInitialScroll) {
                //if scroll position changed
                boolean scrollUp = (scrolledOffset - mainItemDisplayer.mInitialScroll) < 0;
                mainItemDisplayer.mInitialScroll = scrolledOffset;

               if (scrollUp){
                   Log.d("Scrolling", "UP");

               } else {
                   //mainItemDisplayer.setEnabled(false);
                   //Scrolling down
                   Log.d("Scrolling", "DOWN");
                   FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) mainItemDisplayer.getLayoutParams();
                   //layoutParams.setMargins(0, mainItemDisplayer.mInitialScroll, 0, 0);

                   layoutParams.height += scrolledOffset;
                   mainItemDisplayer.setLayoutParams(layoutParams);
                   //((FrameLayout.LayoutParams) mainItemDisplayer.getLayoutParams()).setMarginEnd(mainItemDisplayer.mInitialScroll);
                   //mainItemDisplayer.setLayoutParams(layoutParams);
                   return;
               }
            }
            //mainItemDisplayer.setEnabled(true);
        }

I'm not sure I understand what you want to achieve, but it sounds like what you need are only two xml attributes for your listview :

paddingTop="<yourmargin>dp"

and (the trick!)

clipToPadding="false"

.
