Android TextView顺畅滚动

Question

在我的应用程序中，我有一个可滚动的TextView，但滚动不像ListView那样平滑。

我希望有相同的滚动＆＃34;效果＆＃34;像listview（弹跳，加速，...）

这是我的代码：

sNotes.setMovementMethod(new ScrollingMovementMethod());
                    sNotes.setOnTouchListener(new View.OnTouchListener() {
                        @Override
                        public boolean onTouch(View v, MotionEvent event) {
                            boolean isLarger;
                            isLarger = ((TextView) v).getLineCount()
                                    * ((TextView) v).getLineHeight() > v.getHeight();
                            if (event.getAction() == MotionEvent.ACTION_MOVE
                                    && isLarger) {
                                v.getParent().requestDisallowInterceptTouchEvent(true);
                                moveY = event.getY();
                                touchDown = false;

                            } else {
                                v.getParent().requestDisallowInterceptTouchEvent(false);
                                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                                    touchY = event.getY();
                                    touchDown = true;
                                }
                                else if (event.getAction() == MotionEvent.ACTION_UP) {
                                    float uptouchy = event.getY();
                                    if (touchY == uptouchy) {
                                        expandNotes = false;
                                        myParent.expandNotes = false;
                                        notifyDataSetChanged();
                                    }
                                }
                            }
                            return false;
                        }
                    });
