Example

Installation

repositories {
 maven { url 'https://jitpack.io' }
}

dependencies {
 implementation 'com.github.thelumiereguy:NeumorphismView-Android:1.4'
}

Features

This comes with two custom viewgroups - Framelayout and Constraintlayout. When you just need to add the effect to a single view, use the Framelayout one and if you want to apply the effect to all children, use the Constrantlayout.

There are a few parameters to add a shadow to your view - deltaX, deltaY, color and shadow radius.

• DeltaX - Offset accross the X-Axis

• DeltaY - Offset accross the Y-Axis

• Shadow color - Color for the shadow, duh

• Shadow radius - The blur radius used to render the layer's shadow

Usage

In case of NeumorphicCardView, the params are set to itself, but in case of NeumorphicConstraintLayout, the params are set to each of the children. (Refer to the example)

• Background
• Shadows
• Highlights
• Stroke

Notes -

• To enable preview in the design tab, set the "enable_preview" attribute.
• To avoid the shadow being clipped by the parent view, you'll need to set the padding manually.

Background

	NeumorphicCardView	NeumorphicConstraintLayout
BackgroundColor (Compulsory)	neu_backgroundColor	layout_neu_backgroundColor
BackgroundVerticalPadding	verticalPadding	layout_verticalPadding
BackgroundHorizontalPadding	horizontalPadding	layout_horizontalPadding

DeltaX	shadowDx	layout_shadowDx
DeltaY	shadowDy	layout_shadowDy
Shadow color	shadowColor	layout_shadowColor
Shadow radius	shadowRadius	layout_shadowRadius

Highlights

	NeumorphicCardView	NeumorphicConstraintLayout
Enable Highlights	enableHighlight	layout_enableHighlight
DeltaX	highlightDx	layout_highlightDx
DeltaY	highlightDy	layout_highlightDy
Highlight color	highlightColor	layout_highlightColor
Highlight radius	highlightRadius	layout_highlightRadius

Stroke

	NeumorphicCardView	NeumorphicConstraintLayout
Enable Stroke	enableStroke	layout_enableStroke
Stroke Color	stroke_color	stroke_color
Stroke Width	stroke_width	stroke_width

Modify the Parameters Programmatically

In case of NeumorphicConstraintLayout, the parameters are set to each of the children (Layout Params). Please use the following function on the direct children of the NeumorphicConstraintLayout like this -

childView.updateNeumorphicLayoutParams {
                highlightColor = Color.RED
                highlightRadius = 107F
}

In case of NeumorphicCardView, you can directly modify the properties of the view itself.
