我正在为一个项目编写应用程序。我的问题是如何在第一和第二约束布局之间设置阴影? 我是否需要在drawabale中创建xml以添加到主要的XML中?
我在下面发布了xml,并且如果有必要也放置Java代码。
<?xml version="1.0" encoding="utf-8"?>

感谢您的回答。

您可以像这样使用Cardview:
app:cardUseCompactPadding =“ true”
还要在清单文件中提及 android:hardwareAccelerated =“ true”
<android.support.v7.widget.CardView
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginRight="5dp"
app:cardBackgroundColor="@color/colorprimary"
app:cardCornerRadius="5dp"
app:cardUseCompatPadding="true"
app:elevation="0dp">
</android.support.v7.widget.CardView>
