Question

目前我有一个代码，我有一个recyclerview和cardview。 recyclerview适配器将显示列表卡，对于单个卡，数据将不同。这个问题来了。一旦我运行我的应用程序，我将收到requestLayout() improperly called by android.widget.LinearLayout警告，此警告将中断我的应用程序流程，因为在出现以下警告后我无法启动任何活动。下面是我的logcat和xml。谢谢。

在进一步查看代码后，我发现这是我的LinearLayout（card_location_container＆amp; card_jobtype_container）卡片视图产生问题。我尝试更改为RelativeLayout，但整个CardView消失了。

如果我将其更改为RelativeLayout

尝试使用此布局并根据需要进行排列

LinearLayout导致android.widget.LinearLayout不正确地调用“requestLayout（）”
