gallery last image fix

Question

除了當我點擊向前或向後通過我的圖像時，我幾乎都會按照我想要的方式使用這個東西，一旦碰到數組長度，下一張圖片就不會顯示。當我添加checkImage（）方法時，這只是一個問題。任何人都可以看到我錯了什麼？

幾件事情浮現在腦海中：

1）指數是一個全局變量和函數參數：param - 相沖突？

2）checkimage功能，您在 '索引' 通過，但指0 getChildAt和RemoveChildAt

3）你不叫showimage在checkimage如果NUMCHILDREN> 0成立

我我想跟蹤所有這些，以便將其整理出來。
