Android studio （Android Studio）在我的GridView中单击时的某些位置不'；我不能在非常特殊的情况下工作
好吧，我搞不懂这个错误。它非常具体，我在网上找不到任何帮助。我正在Android Studio中用Android studio （Android Studio）在我的GridView中单击时的某些位置不'；我不能在非常特殊的情况下工作,android-studio,gridview,position,Android Studio,Gridview,Position,好吧，我搞不懂这个错误。它非常具体，我在网上找不到任何帮助。我正在Android Studio中用GridView和ImageAdapter制作一个跳棋游戏。我的代码对大多数人来说可能是一团糟，但希望有人能读懂它并找出我的问题 问题是我的棋盘格不会移动到棋盘上的某些位置。此图像中的绿点是它拒绝移动到的点： OnItemClickListener中的所有内容都是棋盘游戏逻辑，它通过重置ImageAdapter重新绘制棋盘 编辑：我被要求将代码缩减到我认为问题所在的地方，但我不完全确定它到底在哪里。
GridViewImageAdapterOnItemClickListenerImageAdapter/reddit上的u/anomie-p： 我还没有做过很多android开发，但是你能不能连接一个调试器，设置一个断点并逐步执行它 此外，您可能希望使游戏逻辑成为自己的东西，它可以代表游戏并独立于用户界面执行游戏操作，然后将用户界面连接到该界面上进行调用。这会让你做一些事情，比如旋转一个游戏的表现和单元测试。当你想要的时候，它还可以让你更容易地翻转AI的哪一面。现在，用户界面代码会跟踪轮到谁了 你也有很多重复你自己的话。我是说，我想你知道你需要清理，所以也许我应该停止说话 今天早上我有一些轻松的东西要开始工作，但也许在那之后，我会把android的东西拉下来，然后再加上一点——但你肯定应该用调试器和断点来运行它，然后找出哪里出了问题 ~~你能告诉我你的绘图工具需要什么xml/什么吗？这对我来说既简单又方便——我已经在android studio中加载了这些内容，我想我可以创建缺少的可绘制定义，但仅仅拥有你已经得到的似乎更简单/更不容易出错~~ 我只是做了一些看起来很有效的 问题是：您正在计算位置数组之外的索引，并试图访问它们。因此运行时抛出ArrayIndexOutOfBoundsException，应用程序崩溃 表达方式如下： （位置[位置-18]==5 | |位置[位置-18]==9）和&（位置[位置-9]==4 | | |位置[位置-7]==8）和位置[位置]==2 将为小于18或大于（placement.length-19）的任何位置提供索引 我的建议仍然是重写以不同的方式组织的东西，这样你的游戏逻辑就不会与UI如此紧密地联系在一起——但是如果你想继续这样做，可以做类似的事情
private boolean isPlaceEqual(int position, int offset, int value)
{
int index = position + offset;
if(index > -1 && index < placement.length)
{
return placement[index] == value;
}
return false;
}
private boolean isPlaceEqual（int位置、int偏移、int值）
{
int索引=位置+偏移量；
如果（索引>-1&&indexelse if（isplaceeEqual（位置，-18,5）| isPlaceEqual（位置，18,9）.（并在检查放置数组的任何位置使用安全边界检查谓词，以确保值的一致性-如果没有偏移量，只需将其传递为零）Hi Miro！你能把你的问题简化为一个吗？谢谢！好吧，我添加了一段可能存在问题的代码，尽管我不能100%确定这是否是问题的一部分。这是我面临的问题之一。
