Android state_selected不再四舍五入了吗？

Question

该选择器曾经起作用，但是当我最近打开项目时，我注意到此UI错误，其中选定状态不再舍入。有什么想法吗？

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

    <item android:drawable="@drawable/tab_indicator_selected"
        android:state_selected="true"/>

    <item android:drawable="@drawable/tab_indicator_default"/>
</selector>


<?xml version="1.0" encoding="utf-8"?>

            android:shape="ring"
            android:thickness="2dp"
            android:useLevel="false">
            <solid android:color="@android:color/darker_gray"/>
        </shape>
    </item>
</layer-list>
