<declare-styleable name="ShadowViews"> <attr name="shadow_radius" format="dimension" /> <attr name="shadow_color" format="color" /> <attr name="shadow_dx" format="dimension" /> <attr name="shadow_dy" format="dimension" /> <attr name="shadow_inset" format="dimension" /> <attr name="shadow_corner" format="dimension" /> <attr name="shadow_corner_tl" format="dimension" /> <attr name="shadow_corner_tr" format="dimension" /> <attr name="shadow_corner_bl" format="dimension" /> <attr name="shadow_corner_br" format="dimension" /> <!-- 作用于阴影上层的background,因为绘制流程的原因无法自定义控制background的bound,所以需要替换android:background属性 --> <attr name="shadow_background" format="reference|color" /> <!-- 自动设置预留阴影的padding,默认值为true,如果不需要可设置为false但是需要自己设置预留空间或者设置clipChildren=false属性 --> <attr name="include_shadow_padding" format="boolean" /> </declare-styleable>
<com.lowae.shadows.widgets.ShadowFrameLayout android:id="@+id/shadow_layout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_marginBottom="100dp" app:include_shadow_padding="true" app:shadow_color="#8BC34A" app:shadow_corner="0dp" app:shadow_dx="0dp" app:shadow_dy="0dp" app:shadow_inset="0dp" app:shadow_radius="20dp"> <ImageView android:id="@+id/image" android:layout_width="200dp" android:layout_height="200dp" android:scaleType="centerCrop" android:src="@drawable/img" /> </com.lowae.shadows.widgets.ShadowFrameLayout>
