config in xml：

    <com.lijiankun24.shadowlayout.ShadowLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginTop="30dp"
        app:shadowColor="#66000000"
        app:shadowShape="rectangle"
        app:shadowDx="0dp"
        app:shadowDy="3dp"
        app:shadowRadius="10dp"
        app:shadowSide="all">

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@android:color/white"
            android:contentDescription="@null"
            android:src="@mipmap/ic_launcher"/>
    </com.lijiankun24.shadowlayout.ShadowLayout>

There are 6 properties in xml:

app:shadowColor="#66000000" set the color of shadow，notice：Color must have a alpha value
app:shadowShape="rectangle|oval" set the shape of shadow：rectangle|oval
app:shadowDx="0dp" set the shadow x-axis offset
app:shadowDy="3dp" set the shadow y-axis offset
app:shadowRadius="10dp" set the radius of shadow
app:shadowSide="all|left|right|top|bottom" set the display boundary (all|left|right|top|bottom) of shadow

Change shadow dynamically

// change the color of shadow
ShadowLayout slOval = findViewById(R.id.sl_oval);
slOval.setShadowColor(ContextCompat.getColor(this, R.color.drak_yellow))

// change the color of shadow
ShadowLayout slRectangle = findViewById(R.id.sl_rectangle)
slRectangle.setShadowColor(Color.parseColor("#EE00FF7F"));

// change the radius of shadow
ShadowLayout slRadius = findViewById(R.id.sl_radius);
slRadius.setShadowRadius(dip2px(12))
