android - 为什么 view flipper 中出现 stackoverflow 错误？

Question

我在 android 应用程序中使用 viewflipper。

我的应用程序在 tabhost 中有 tabhost。当我点击“主页”选项卡时——> 点击“节食”按钮——> 然后它会显示新的标签主机，例如早餐、午餐等。

当我在 lunch tab 中使用 view flipper 时，它有两个按钮 home 和 office 然后两个按钮通过 view flipper 切换布局，但是当午餐选项卡打开时它显示 stackoverflow 错误。

我也尝试了 layoutinflater 和其他选项期望 view flipper 但它显示相同的错误。

这是 logcat 错误

Answer 1

哦!我明白了，我需要更改对我来说很容易的文本框值。因为我的布局在选项卡中的选项卡中。所以它无法清除堆栈，所以最好的方法是清除堆栈，然后替换我们想要的 TextView 的名称。
