我需要使用"from zelplin"这些属性为按钮添加阴影:

I need to add a shadow to a Button with these attributes "from zelplin":

这是设计

我尝试了这段代码

<Button android:id="@+id/btn_sign_in" android:layout_width="match_parent" android:layout_height="48dp" android:layout_marginTop="35dp" android:background="@drawable/auth_button_shape" android:shadowColor="#41ff4800" android:shadowDx="0" android:shadowDy="8" android:text="@string/sign_in" android:textAllCaps="true" android:textColor="@android:color/white" android:textSize="14sp" />

auth_button_shape

auth_button_shape

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="schemas.android/apk/res/android" android:shape="rectangle"> <solid android:color="#ff7c44" /> <corners android:radius="100dp" /> </shape>

但不起作用，其他属性模糊"和传播"如何为按钮设置它们.

But not worked and the other attributes "Blur" and "Spread" How I can set them for the button.

谢谢.
