我有一个listview，根据位置（覆盖getViewTypeCount（）和getItemViewType（int position）来实现它，膨胀4种不同类型的行布局。）每行都有一个Image和其他textview和按钮。我在一个seaparate线程中加载图像。我正在使用android视图模式来缓存每个行类型的视图。
当我从一种行布局滚动到另一行布局时，我观察到滚动时的急动。
任何改进的提示都将受到赞赏。

答案 0 :(得分：1)
确保您不使用Adapter.getView()方法加载或处理任何图像。如果您需要这样做，请在单独的AsyncTask中进行。如果您从Internet下载图像，最好使用一些辅助库，如Volley或Picasso
答案 1 :(得分：0)
我使用此库在列表视图中加载图像，我从未遇到过问题：Android Image Loader
