滚动到Android Scrollview中的特定位置时如何取消滚动？

Question

I have a problem while scrolling in Scrollview. I would like to cancel scrolling immediately when I've scrolled to a specific position (like end of scrollview). That means my finger is still held on screen, but Scrollview can't scroll anymore. How can I accomplish this?

Answer 1

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
   if (!mScrollable) return false;
     else return super.onInterceptTouchEvent(ev);
}

Answer 2

If you want to cancel/stop scroll when you have reached particular position, you can use smoothScrollToPosition(int pos), where pos is the adapter position.

Also to make it a smooth experience for user, you can tell the listview to post it when ui thread is free:

getListView().post(new Runnable() {
    @Override
    public void run() {
        getListView().smoothScrollToPosition(pos);
    }
});
