android - Surface 在 Android 应用程序上无效

Question

您好 appcelerator 专家，

我目前正在编写一个带有 3 个窗口(合金)的简单应用程序。按下按钮时，窗口会依次出现，因此窗口 1 会显示一个按钮 -> 转到窗口 2 -> 按其按钮 -> 窗口 3。使用后退按钮可以返回到之前的窗口。

问题是应用程序在窗口之间切换时有时会崩溃并重新启动并产生错误“ViewRootImpl #2 Surface is not valid”，我不知道如何解决。任何人以前见过这个问题或猜测可能是什么问题？也许 eventListeners 经常被删除？

对于任何有类似问题的人，我已经通过将按钮移到他们的 View 之外解决了这个问题:

<View class="vbutton">
    <Button id="getstarted" ></Button>  
</View>

进入:

    <Button id="getstarted" ></Button>
