我收到了 FC 的堆栈跟踪，但无法重现 FC。我错过了什么？

在 java 代码中，一些 View 根据应用程序的状态设置为 View.GONE 或 View.VISIBLE。在 LayoutParams 中，我只更改大小和边距。

两个嵌套的 RelativeLayouts 是因为 Activity 有一个半透明的主题，第二个是用于用户可以应用的 alphafilter。

任何帮助都会很棒!

最佳答案

我看了一下你的 xml，它看起来不像你有任何循环引用，如果你说你正在设置一些 View ，我会看看 android:layout_alignWithParentIfMissing="true" 你可以找到一个例子 here

我也会尝试不将您的任何 View 设置为已消失，看看您是否还有问题。

关于android - 如何在 RelativeLayout 中找到导致循环依赖的原因，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16047781/
