Java 如何在另一个活动中增加滑动时ArrayList的位置

我正在练习一个应用程序。我制作了一个位置数组，一个网格视图，它在

GridView

中显示第0个位置，在

ImageView

中显示第1个位置。对于网格视图，在另一个名为answer的活动中单击网格视图时显示第2个位置。在回答活动中，我想让它转到另一个问题，但我不明白。你能帮我吗？这是下面的密码。

我没有检查所有的代码，但是通常，

post increment

“clickedPosition++”将发送当前值，然后将其增加1，因此尝试使用

pre increment

“+++clickedPosition”并查看结果，它可能会解决问题（减量（--）的概念相同我试过一次，刷卡动作只起作用了一次。再次刷卡时，它应该转到下一个答案，即ClickedPosition应该递增并保存，再次刷卡时，然后递增并保存。我没有检查所有代码，但通常是

递增后

“ClickedPosition++”将发送当前值，然后将其增加1，因此尝试使用

预增量
