获取无效的指针例外, 是否在单个标签中使用多个活动来更改标签? @ info: whatsthis
原标题:Getting null pointer exception changing tab from activity using multiple activities in single tab ?

我将解释我的问题。 我有 4 个标签, 每个标签有多个活动。 现在我已经创建了 4 个标签组活动, 扩展活动组来处理多个活动 。 现在有一个情况, 我必须去第 2 个标签组活动所生的活动 。 我想将当前标签修改为 2 。 但是它允许我在标签主机上设置无效的指针例外 。

如何改变第一个活动组的 ta 和 goo 到第二个活动组? 请给出想法 。 或任何示例 说明我如何执行?

提前感谢
