Wear OS Color Picker

A color picker activity optimized for Wear OS (aka 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 aar artifact is available at the jcenter repository. Declare the repository and the dependency in your build.gradle file:

repositories {
    jcenter()
}

 (...)

dependencies {
    compile 'org.jraf:android-wear-color-picker:2.2.3'
}

The library uses Android Data Binding - make sure your build.gradle declare that:

android {
    buildFeatures {
        dataBinding = true
    }
}

Use the library

Start the pick color activity:

Intent intent = new ColorPickActivity.IntentBuilder()
    .oldColor(oldColor)
    .colors(myListOfColors) // <- optional, specify your own list of colors to be used instead of a "rainbow" preset
    .build(this);
startActivityForResult(intent, REQUEST_PICK_COLOR);

Get the picked color:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case REQUEST_PICK_COLOR:
            if (resultCode == RESULT_CANCELED) {
                // The user pressed 'Cancel'
                break;
            }

            int pickedColor = ColorPickActivity.getPickedColor(data);
            Log.d("pickedColor=" + Integer.toHexString(pickedColor));
            break;
    }
}

That's it!
