Download sample apk

The current minSDK version is API level 16.

Download :arrow_down:


Gradle:

groovy
implementation 'com.github.armcha:ColoredShadowImageView:1.1.0'

Setup and usage

  1. You also need to add RenderScript to your app module. Add these lines to the defaultConfig block of your build.gradle.

    groovy
    renderscriptTargetApi YOUR_TARGET_SDK_VERSION
    renderscriptSupportModeEnabled true 
    
  2. Static image

    xml
    
    
    Or
  findViewById(R.id.shadowImage).apply {
       setImageResource(R.drawable.android)
  }
  1. If you are using Glide, use it in this way. Glide transformations are also supported. Now we have some limitations for Glide transitions.
//shadowView.radiusOffset = 0.4f
//shadowView.shadowColor = ContextCompat.getColor(context,R.color.green)

GlideApp.with(itemView.context) .load(item.imageUrl) .placeholder(R.drawable.place_holder) .error(R.drawable.place_holder) //.transform(CircleCrop()) .into(object : ViewTarget(shadowView) { override fun onLoadStarted(placeholder: Drawable?) { super.onLoadStarted(placeholder) shadowView.setImageDrawable(placeholder, withShadow = false) }

                    override fun onLoadCleared(placeholder: Drawable?) {
                        super.onLoadCleared(placeholder)
                        shadowView.setImageDrawable(placeholder, withShadow = false)
                    }

                    override fun onLoadFailed(errorDrawable: Drawable?) {
                        super.onLoadFailed(errorDrawable)
                        shadowView.setImageDrawable(errorDrawable, withShadow = false)
                    }

                    override fun onResourceReady(resource: Drawable, transition: Transition<in drawable>?) {
                        shadowView.setImageDrawable(resource)
                    }
                })

Customizations

You can change shadow radius. Default radius is 0.5. You can change it between 0 and 1. (0 < radius ≤ 1)

kotlin
  shadowImageView.radiusOffset = 0.4f
  shadowImageView.setImageResource(R.drawable.android)

You can also change the shadow color

kotlin
  shadowImageView.shadowColor = ContextCompat.getColor(context,R.color.green) //or Color.RED
  shadowImageView.setImageResource(R.drawable.android)
or from xml
xml
   app:radiusOffset="0.6"
   app:shadowColor="@color/colorAccent"

Current limitations: :triangularflagon_post:

  • You can't use the library when setting width or height to
    WRAP_CONTENT

Add proguard rules if necessary:

-keep class android.support.v8.renderscript.** { *; }
