Wear OS Color Picker

A color picker activity optimized for Wear OS (formerly known as Android Wear). Handy for watch face settings.

The UI presents a wheel of colors with different hues and lightness.

How to use

Adding the library to your project

The artifact is available on Maven Central.

dependencies {
    implementation("org.jraf:android-wear-color-picker:3.0.0")
}

Note: the artifact was hosted on JCenter in the past, but is now on Maven Central since v2.2.4

Use the library

The picker uses the ActivityResultContract API to be launched and to return the picked color:

// 1. Setup the pick launcher
val colorPickLauncher = registerForActivityResult(ColorPickActivity.Contract()) { pickedColorResult ->
    if (pickedColorResult == null) {
        // The user closed the picker without picking anything
    } else {
        // Get the picked color. The result is an Int in the form 0xAARRGGBB.
        pickedColor = pickedColorResult.pickedColor
    }
}

// ...

// 2. Launch the picker. The picked color parameter is optional - if specified, the picker will start already positioned on that color.
colorPickLauncher.launch(ColorPickActivity.Contract.PickRequest(pickedColor))
