Android- Scrollview : change layout position by dragging

Question

Hi,

I create Scrollview with 10 layout. I want to change the layout position by dragging.

layout_view.setOnTouchListener(new View.OnTouchListener() {

@Override

public boolean onTouch(View v, MotionEvent ev) { final int action = ev.getAction();

switch (action) {
case MotionEvent.ACTION_DOWN: { ...

The problem is when i dragging DOWN/UP (When I dragging right/left it's work perfect): 1) MotionEvent.ACTION_CANCEL happen 2) the Scrollview is moving

1)How Can I disable Scrollview scrolling when I dragging my layout? 2) Do you have any idea how to stay in layout without getting MotionEvent.ACTION_CANCEL?

Thanks
