安卓 2.3 : GridView out of order after scrolling

Question

我有一个加载了一堆自定义 View 的 GridView。当我向上或向下滚动时，之前离开屏幕的 View 现在被不同的 View 所取代。知道为什么会这样吗？

    public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView;
    LayoutInflater inflater =  (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    RelativeLayout rLayout = (RelativeLayout)inflater.inflate(R.layout.collection_item, parent, false);

    if (convertView == null) {  // if it's not recycled, initialize some attributes    
        ImageView movieImage = (ImageView)rLayout.findViewById(R.id.movieImage);
        TextView movieTitle = (TextView)rLayout.findViewById(R.id.movieTitle);
        TextView movieDescription = (TextView)rLayout.findViewById(R.id.movieDescription);

        movieImage.setImageResource(movies[position]);
        movieTitle.setText(movieNames[position]);
        movieDescription.setText(movieDescriptions[position]);
    } else {
        rLayout = (RelativeLayout) convertView;
    }
    return rLayout;
}

没关系，我想通了。只需将所有初始化代码放入 (convertView == null) 部分和 if/else block 之后的 setter 方法。
