我将android.support.v7.widget.CardView用于布局xml.但是，当我在CardView中放置LinearLayout时，Android Studio给我以下错误" 此处不允许使用元素LinearLayout ".

I am using android.support.v7.widget.CardView for my layout xml. However when I place a LinearLayout within the CardView, Android Studio gives me the following error "Element LinearLayout is not allowed here".

实际上 ANY 类型的小部件(例如TextView)会导致此错误，我尝试了

In fact ANY types of widgets (like TextView) would cause this error, I have tried solutions from LinearLayout flagged if used in CardView link, which was to restart Android Studio. But it did not work. Below is my xml code:

    android:layout_height="wrap_content">

    <LinearLayout>
