如何创建这样的背景形状

Question

我有cardview，目前看起来像这样。这些cardviews 在list view 内。 我需要这样创作吗？

请问有什么帮助吗？

编辑

感谢 Marsad 和 Zain 的回答。但是，我可以设法得到这个。但是我无法从下面指出的视图中删除形状下的 corner background。

另外，这个视图如何获得玻璃视图？完整的xml 已更新。

Answer 1

你可以这样做

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid
        android:color="#2196F3"/>


    <corners
        android:topLeftRadius="20dp"
        android:bottomRightRadius="20dp"/>

</shape>

更新

这是更新的背景可绘制对象

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:height="300dp">

        <shape>
            <solid android:color="#EE7A72" />

            <corners
                android:bottomRightRadius="20dp"
                android:topLeftRadius="20dp"
                android:topRightRadius="20dp" />

        </shape>

    </item>

    <item
        android:height="100dp"
        android:top="200dp">

        <shape>

            <solid android:color="#3197F4" />

            <corners
                android:bottomRightRadius="20dp"
                android:topLeftRadius="20dp" />

        </shape>

    </item>

</layer-list>

移除卡片视图角背景

android:backgroundTint="@android:color/transparent"

Answer 2

这是CardView 布局，使用了几个drawable 和一个vector drawable

<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        <View

            android:background="@drawable/top_view"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

        <View

                app:layout_constraintBottom_toBottomOf="parent"
                app:layout_constraintEnd_toEndOf="parent"
