Animation resetting view state?

Question

Hi, i am trying to do some simple animation, i have list with items, those items include also checkboxes on a checkbox button click i want to show with animation some button from the buttom, something like this:

private int mPosition; private CheckBox chkBox;

    OnItemClickListener(CheckBox mChkBox, View v)
    {

        chkBox = mChkBox;
        chkBox.setClickable(false);
        chkBox.setChecked(false);
        chkBox.setClickable(true);

    }

    @Override
    public void onClick(View v)
    {
        if (chkBox.isChecked())
                        {

                                  animation = AnimationUtils.loadAnimation(context,
                R.layout.animation_slide_in);
                animation.setDuration(500);
                animation.setInterpolator(new  AccelerateInterpolator());
                btDeleteItms.startAnimation(animation);
                btDeleteItms.setVisibility(btDeleteItms.VISIBLE);

                        }

now the wierd thing, that after i click the checkboxbutton, the animation does work fine,but the state of the triggering checkbox button, is being uncheck unexpectdly? how come? does animation resetting states somehow?

Thaks,

ray.
