解决ScrollView里嵌套RecyclerView没有惯性滚动

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
downX = ev.getX();
downY = ev.getY();
onTouchEvent(ev);
return false;
case MotionEvent.ACTION_MOVE:
if ((Math.abs(ev.getX() - downX) < CLICK_SIZE && (Math.abs(ev.getY() - downY) < CLICK_SIZE))
|| Math.abs(ev.getX() - downX) > Math.abs(ev.getY() - downY)) {
onTouchEvent(ev);
return false;
}
return true;
default:
return super.onInterceptTouchEvent(ev);
}
}
