我正在尝试在Android中制作可自定义的图标。我制作了矢量元素,但现在我想给它一个圆形背景,所以我试着将它放在一个圆形的形状中。像这样:

<?xml version="1.0" encoding="utf-8"?>
<!-- drawable/circle_card_icon.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:height="24dp"
        android:width="24dp"
        android:viewportWidth="24"
        android:viewportHeight="24">
        <path android:fillColor="#000"
            android:pathData="M20,2H4A2,2 0 0,0 2,4V22L6,18H20A2,2 0 0,0 22,16V4A2,2 0 0,0 20,2M6,9H18V11H6M14,14H6V12H14M18,8H6V6H18" />
    </vector>
</shape>

然而,这不起作用,我正在努力实现以下目标:

仅使用矢量我不会得到背景 (我用this website生成了矢量)

我没有将矢量放入形状,而是使用LayerList Drawable

像这样:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <!-- drawable/circle_card_icon.xml -->
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="oval">
            <solid android:color="#8df"/>
            <size 
                android:width="48dp"
                android:height="48dp"
            />
        </shape>
    </item>
    <item android:drawable="@drawable/your_vector_drawable" />
</layer-list>

如果您有2个向量,则可以尝试使用此方法(最小API 23):

ic_heart_in_star:

    <?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/ic_star"  />
        <item android:drawable="@drawable/ic_heart"
            android:gravity="center"
            android:width="3dp"
            android:height="3dp"  />
    </layer-list>

ic_heart:

    <vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:width="24dp"
        android:height="24dp"
        android:viewportWidth="24.0"
        android:viewportHeight="24.0">
        <path
            android:fillColor="#FF0000"
            android:pathData="M12,21.35l-1.45,-1.32C5.4,15.36 2,12.28 2,8.5 2,5.42 4.42,3 7.5,3c1.74,0 3.41,0.81 4.5,2.09C13.09,3.81 14.76,3 16.5,3 19.58,3 22,5.42 22,8.5c0,3.78 -3.4,6.86 -8.55,11.54L12,21.35z" />
