如何在RelativeLayout中找到导致循环依赖的内容

标签： android android-layout relativelayout

我正在接收FC的堆栈跟踪，但我无法重现FC。我错过了什么？

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

2嵌套RelativeLayouts是因为活动具有半透明主题，第二个是用于可由用户应用的alphafilter。

任何帮助都会很棒！

我看起来想你的xml并且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视图已经不见了我看看android:layout_alignWithParentIfMissing="true"你可以找到一个例子{ {3}}

我也不会尝试将您的任何观点设置为已消失，看看您是否还有问题。

通常，当您将视图A设置为与另一个视图B对齐，并且视图B与A对齐时，会发生这种情况，从而产生循环依赖关系。

当您设置另一个视图的ID时，会出现上面，下面的属性以及对齐。
