主要问题

当我第二次单击“ListView”项目时，出现错误并且应用程序关闭。

有人可以告诉我我做错了什么，因为它第一次完美地与每个元素一起工作，而第二次它甚至不工作，即使是第一次单击的 ListView 项目（没有任何问题）再次单击。

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

在这里，您收到错误消息，根据错误消息，它的值变化太大，因此它的 Long 不是 Int 值。在 MainActivity 中签入 onCreate()

已编辑

在单击项目中，您正在选择资源并存储在一个对象中，这个对象现在附加在sb对象中，现在每次单击它都会附加它。

temp=""+sb.append(a); // here appended a (selected resource value)

您需要每次清除此值，或者您可以将其传递给意图对象中的另一个额外值

in.putExtra("resourceId", a);

然后就MainActivity不需要解析和类型转换问题，只需获取 int 值并直接用于BitmapFactory，就像这样

Bitmap foto = BitmapFactory.decodeResource(getResources(),extras.getInt("resourceId"));

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

是错误所在的行，更具体地说：

Integer.parseInt(podatki.get(pic))

根据 logcat，它看起来podatki.get(pic)返回的字符串太长而无法转换为整数。

问题出在代码中的这一行。

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

如下更改

 Bitmap foto = BitmapFactory.decodeResource(getResources(),
                    R.drawable.yourpic);

希望能帮助到你
