我尝试使用该代码，但似乎不正确，请帮助

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

<item>
<rotate
android:fromDegrees="45"
android:pivotX="35%"
android:pivotY="30%">
<shape>
<size android:height="5dp" android:width="5dp"/>
<corners android:radius="0.5dp" />
<solid android:color="@color/white" />
</shape>
</rotate>
</item>

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners
android:topLeftRadius="12dp"
android:topRightRadius="12dp"
android:bottomLeftRadius="75dp"
android:bottomRightRadius="9dp"
/>
<gradient
android:angle="45"
android:centerX="35%"
android:centerColor="#47A891"
android:startColor="#E8E8E8"
android:endColor="#000000"
android:type="linear"

<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp"
/>
<size

使用向量drawable可能会更容易：

<vector android:height="24dp" android:viewportHeight="101.01621"
    android:viewportWidth="114.45102" android:width="24dp" xmlns:android="http://schemas.android.com/apk/res/android">
    <path android:fillColor="#00000000"
        android:pathData="m0.421,7.319c-0.848,-4.225 2.893,-6.292 4.701,-6.534l93.265,-0.552c9.395,-0.736 15.906,2.42 15.875,15.875l-0.032,78.398c1.262,7.668 -11.009,7.894 -15.926,3.48 -17.528,-8.582 -70.939,-31.855 -92.048,-40.468 -1.899,-0.775 -3.147,-1.13 -4.14,-1.522 -2.225,-0.879 -2.097,-3.281 -1.851,-5.335z"
        android:strokeAlpha="1" android:strokeColor="#000000"
        android:strokeLineCap="butt" android:strokeLineJoin="miter" android:strokeWidth="0.26458332"/>
</vector>

如果需要进行一些调整，请阻止下载Inkscape（https://inkscape.org）或其他svg设计软件以及我的源文件（如果需要）https://drive.google.com/open?id=1vY8tYcA00KAQeoulMlPmwvRWrs7EY672。绘制形状，然后再次将其导出为svg。将文件转换为svg格式后，即可使用Android Studio中的矢量资产工具。该工具会自动生成矢量xml，并且您可以将矢量可绘制对象用作普通可绘制对象，例如，用作ImageView的源。希望对您有帮助！

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

    <!-- view background color -->
    <solid
        android:color="#142737" >
    </solid>

    <!-- Here is the corner radius -->
    <corners
        android:radius="10dp"   >
    </corners>

将此xml文件放置在drawable文件夹中，并将其设置为按钮的背景，例如：
android：background =“ @ drawable / oval_background”
