下午好,我正在尝试使用阴影创建带有ImageButton的图像.

要做到这一点 :

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:padding="5sp">

    <ImageButton
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/circle_shape_little"
        android:src="@drawable/ic_keyboard_arrow_right_black_24dp"
        android:elevation="3sp"/>
</LinearLayout>

但结果如下:

如你所见,边界是"切",我不知道为什么.

有人能帮帮我吗？谢谢.
