代码示例

代码示例来源：origin: ksoichiro/Android-ObservableScrollView

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
  if (hasNoCallbacks()) {
    return super.onInterceptTouchEvent(ev);
  }
  switch (ev.getActionMasked()) {
    case MotionEvent.ACTION_DOWN:
      // Whether or not motion events are consumed by children,
      // flag initializations which are related to ACTION_DOWN events should be executed.
      // Because if the ACTION_DOWN is consumed by children and only ACTION_MOVEs are
      // passed to parent (this view), the flags will be invalid.
      // Also, applications might implement initialization codes to onDownMotionEvent,
      // so call it here.
      mFirstScroll = mDragging = true;
      dispatchOnDownMotionEvent();
      break;
  }
  return super.onInterceptTouchEvent(ev);
}
