Appcompat"java.lang.IllegalArgumentException:参数必须是此视图的后代"在ViewGroup.offsetRectBetweenParentAndChild中

Question

我在上个月随机遇到这个问题:

java.lang.IllegalArgumentException: parameter must be a descendant of this view
   at android.view.ViewGroup.offsetRectBetweenParentAndChild(ViewGroup.java:4479)
   at android.view.ViewGroup.offsetDescendantRectToMyCoords(ViewGroup.java:4416)

   at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:557)
   at dalvik.system.NativeStart.main(NativeStart.java)

经过大量的挖掘和测试后,我发现问题是在更新Appcompat lib(android-support-v7-appcompat)后于10月27日引入的.最新版本的Appcompat似乎无法解决此问题.

我想这个问题与类似的错误没有关系(比如这个问题),因为我已经隔离了在我的repo上引入问题的提交,它是包含Appcompat更新的提交.

这有什么线索吗？那里有同样问题的人？

您是否尝试过正确设置视图的可聚焦性？：

mYourView.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);

或在 XML 中

android:descendantFocusability="blocksDescendants"
