hi, i find a way to solve setSelection.

  private int mChildWidth;

  @Override
  public void setSelection(int position) {
    if(mChildWidth == 0) {
      mChildWidth = getSelectedView().getWidth();
    }

    int positionX = position * mChildWidth;
    if (positionX <= 0) {
      positionX  = 0;
    }
    int maxWidth = mAdapter.getCount() * mChildWidth;
    if (positionX > maxWidth) {
      positionX = maxWidth;
    }

    scrollTo(positionX);
    mCurrentlySelectedAdapterIndex = position;
  }

here are some problem if you use the code above,you will get NullPointException at "getSelectedView()",you can try like this
if (mChildWidth == 0) {
View selectedView = getSelectedView();
if (selectedView != null) {
mChildWidth = selectedView.getWidth();
}
}
and then modify the method
@OverRide
public View getSelectedView() {
View kid = getChild(mCurrentlySelectedAdapterIndex);
if(kid != null){
kid.setSelected(true);
}
return kid;
}
@yuxiangping i am not sure whatever you had encountered this type of problem
