java - 我的程序在列表 View 中的第二次单击时崩溃

解决了 ;）
我知道这是蝙蝠的主意，但我使用了Globals .class，现在可以了；）
现在可以了;）hurahhh

感谢大伙们

主要问题

当我第二次单击“ ListView”项时，发生错误，该应用程序关闭。

有人可以告诉我我在做什么错，因为它第一次可以完美地与每个元素配合使用，而第二次却不起作用，即使是第一次单击（没有任何问题）的ListView项也可以再次使用。

最佳答案

Bitmap foto = BitmapFactory.decodeResource(getResources(),
                Integer.parseInt(podatki.get(pic)));

错误所在的行，更具体地说：

Integer.parseInt(podatki.get(pic))

根据logcat，看来podatki.get(pic)返回的字符串太长，无法转换为Integer。
