android - 图层列表被裁剪为可绘制

Question

这是我正在尝试构建的所需可绘制对象。

问题:

据我所知，图层列表的大小取决于其中的最后一项。但是如果我使用 android:drawable内部标签 <item> , 层列表被裁剪到可绘制大小并不重要它在什么位置。

这是我的 swipe_close.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape
            android:innerRadius="0dp"
            android:shape="ring"
            android:thickness="34dp"
            android:useLevel="false">
            <solid android:color="#ffffff" />
        </shape>
    </item>
    <item android:drawable="@drawable/ic_close_swipe" />
    <item>
        <shape
            android:innerRadius="34dp"
            android:shape="ring"
            android:thickness="10dp"
            android:useLevel="false">
            <solid android:color="#E6E6E6" />
        </shape>
    </item>
</layer-list>

还有 ic_close_swipe.xml

<vector xmlns:android="http://schemas.android.com/apk/res/android"
  android:width="39dp"
  android:height="39dp"
  android:viewportWidth="39"
  android:viewportHeight="39">

我建议按如下方式更改 swipe_close.xml。

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape
            android:innerRadius="0dp"
            android:shape="ring"
            android:thickness="34dp"
            android:useLevel="false">
            <solid android:color="#ffffff" />
        </shape>
    </item>
    <item
        android:bottom="25dp"
        android:drawable="@drawable/ic_close_swipe"
        android:left="25dp"
        android:right="25dp"
        android:top="25dp" />
    <item>
        <shape
            android:shape="ring"
            android:thickness="10dp"
            android:useLevel="false">
            <solid android:color="#E6E6E6" />
        </shape>
    </item>
</layer-list>
