ElevationImageView

Imageview with elevation shadow

How to use ?

Install

Add this to your app build.gradle

dependencies {
    ...
    implementation 'com.qhutch.elevationimageview:elevationimageview:2.4'
}

You will also need support renderscript, also in your build.gradle :

android {
    ...
    defaultConfig {
        ...

        renderscriptTargetApi 18
        renderscriptSupportModeEnabled true
    }
}

Usage

Use as any ImageView, set your image and add elevation (either with elevation attribute, or compatEvelation if your minSdk is below 21)

The clipShadow attribute is set to false by default, if true, it will clip the shadow to the View boundaries.

To set the elevation programmatically, you can use setElevation() and pass a value in pixels or setElevationDp() and pass a value in dp.

Use translucent attribute or setTranslucent() method to make the shadow keep the color of the image
