android gridview+viewpager,根据 position改变item背景。

Question

android gridview+viewpager,怎样根据setOnItemClickListener position改变item背景。
viewpager是循环加入的。
activity里
for (i = 0; i < videoNum / 4; i++) {//我这里的videoNum是20
view = getActivity().getLayoutInflater().inflate(
R.layout.fragment_four_video, null);
if (viewList.size() < (videoNum / 4)) {
viewList.add(view);

            gridView = (GridView) view.findViewById(R.id.gv);
            mAdapter = new BaseMoreAdapter(getActivity(), 2, 2,
                    displaychannels, i);
            gridView.setAdapter(mAdapter);
            gridView.setSelection(0);
            gridView.setOnItemClickListener(onItemClick);
        }
    }
    mVpAdapter = new ViewPagerAdapter(viewList);
    mVPager.setAdapter(mVpAdapter);

    在点击事件里调用了适配器里的方法更换背景
    private OnItemClickListener onItemClick = new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position,
            long arg3) {
        mAdapter.setSeclection(position);
        mAdapter.notifyDataSetChanged();｝

        adapter下
        public void setSeclection(int position) {
    clickTemp = position;
}

adapter getview方法里
if (clickTemp == position) {
        viewHolder.mRlContent.setBackgroundResource(R.drawable.a);
    } else {
        viewHolder.mRlContent.setBackgroundResource(R.drawable.b);
    }

    这样写的结果是，因为循环的关系每次都是操作了最后一页，怎样可以更换viewpager当前页的gridview的item的背景。
