我一直困扰这个问题好几个月了(但现在我正在调整性能)。但是，我现在非常需要知道为什么我的适配器认为有必要在一条记录上最多运行bindView 4次。
我有一个自定义光标适配器，可填充gridview。
一些调试以显示正在发生的事情:

“Avatar empty ...”和“Picture creation ...”只是调试，告诉我它正在处理和更新2个特定的
ImageView。为什么o为什么
bindView运行这么多次？这是什么原因造成的，我该怎么解决？从逻辑上讲，我希望
bindView运行一次(并且每次适配器更新一次)，我是否认为这是错误的？ 最佳答案
操作系统可以多次调用bindView，以便它可以正确地测量和布置列表。这不是必须的方式，而是错误。这以及滚动的顺畅性是bindView实现需要尽可能高效的原因。您可以在Android Developers Page上详细使用一些不错的技巧和窍门。
