android - 在使用 android 4.4 的 android 设备上将 CardView 膨胀到 Recyclerview 时发生 InflateException

Question

当我尝试在版本 4.4 的 Android 设备上膨胀 CardView/RecyclerView 时，我遇到了这个 InflateException 请注意，我在版本超过 4.4 或 Kitkat 的任何设备上都没有遇到这个问题。

请问是异常的stacktrace

难道Kitkat不支持RecyclerView/CardView？还是其他什么原因？请帮忙。

下面是发生异常的代码

 LayoutInflater inflater = LayoutInflater.from(parent.getContext());
            v = inflater.inflate(R.layout.row_layout_course, parent, false);

下面是我要膨胀的 xml。

please find below is the xml code.

Answer 1

尝试从您的 CardView

中删除 tools:targetApi="lollipop"

也用这个

android:foreground="?android:attr/selectableItemBackground"

代替这个

 android:foreground="?android:attr/selectableItemBackgroundBorderless

代码

<android.support.v7.widget.CardView
        android:foreground="?android:attr/selectableItemBackground"
        app:cardCornerRadius="10dp"
        android:layout_width="match_parent"
        android:layout_margin="@dimen/cardview_compat_inset_shadow"
        android:layout_height="wrap_content"
