Question

对于我设置为可点击的CardView，我遇到了一些奇怪的行为。点击它会略微改变卡内部的所有视图，这使得当您停止按卡时看起来很奇怪。

Here is what it looks like when the card is clicked。理想情况下，当手指放在上面时，我希望整张卡片变成粉红色。当你松开时，卡片会均匀地消失为白色。

感谢任何建议！

如果您希望整张卡片的背景有所改变，您应该将您的drawable应用于根CardView - 我不确定为什么您有多个ViewGroup的背景绘制副本应用于

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/cv"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_margin="5dp"
    android:clickable="true"
    android:foreground="@drawable/button_rect_list_normal"
    android:layout_height="wrap_content">

编辑：将android:background更改为android:foreground

CardView
