推荐答案

检查您的适配器，你可能没有做正确的工作bindView（）。你必须重新设置 bindView（）的值。

Check your adapter, you are probably don't do the job right on bindView(). You have to set again on bindView() the values.

我将改写这句话，你可能会就明白了。
在 NewView的（）创建只有5-10次（尽可能多的他们适合在屏幕上），它们是为其他行重复使用。如果你有一个的ListView 200行吧，其实你只有5-10的看法，你必须确保你更新的有效变化的意见， bindView（）。你必须保存/更改保存到以后重复使用的对象。

I will reformulate the sentence and you will probably will understand. The newView() creates only 5-10 views (as many they fit on the screen), and they are reused for other rows. If you have a ListView with 200 lines in it, actually you have only 5-10 views, and you have to make sure you update the views with the valid changes in bindView(). You have to store/save the changes to an object for later reuse.
