将宽度和高度插入size标签中，以便在较低的 API 级别中可用：

<item android:gravity="bottom|center_horizontal">

    <rotate android:fromDegrees="45" android:toDegrees="45"
        android:pivotX="50%" android:pivotY="50%" >

        <shape android:shape="rectangle">

            <size android:width="12dp" android:height="12dp" />

            <corners android:bottomRightRadius="2dp"/>

            <gradient android:type="linear"
                android:angle="0"
                android:endColor="@color/gradient_red"
                android:startColor="@color/gradient_red" />

        </shape>

    </rotate>

</item>

<item android:bottom="6dp">

    <shape android:shape="rectangle">

        <size android:width="120dp" android:height="36dp" />

        <gradient android:type="linear"
            android:angle="0"
            android:endColor="@color/gradient_red"
            android:startColor="@color/gradient_red" />

        <corners android:radius="6dp" />

    </shape>

</item>
