Gradle:
implementation 'com.github.armcha:ColoredShadowImageView:1.1.0'Setup and usage
- You also need to add RenderScript to your app module. Add these lines to the defaultConfig block of your build.gradle.
renderscriptTargetApi YOUR_TARGET_SDK_VERSION
renderscriptSupportModeEnabled true - Static image
<io.github.armcha.coloredshadow.ShadowImageView
android:id="@+id/shadowImage"
android:layout_width="300dp"
android:layout_height="400dp"
android:src="@drawable/android"/>Or
findViewById<ShadowImageView>(R.id.shadowImage).apply {
setImageResource(R.drawable.android)
}- 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<ImageView, Drawable>(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)
shadowImageView.radiusOffset = 0.4f
shadowImageView.setImageResource(R.drawable.android)You can also change the shadow color
shadowImageView.shadowColor = ContextCompat.getColor(context,R.color.green) //or Color.RED
shadowImageView.setImageResource(R.drawable.android)or from xml
app:radiusOffset="0.6"
app:shadowColor="@color/colorAccent"Current limitations: 🚩
- 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.** { *; }Contact 📖
