Documentation

To use SparkButton simply include XML script or build it using SparkButtonBuilder as stated above.

Various attributes that you can control are following:

Button Image and Colors

You can specify both active and inactive image of the button. If only active image is specified SparkButton will behave as a normal button, otherwise as a switch.

SparkButton takes two colors primary and secondary. (It is recommended that primary color is lighter than secondary for better results).

XML

app:sparkbutton_activeImage="@drawable/active_image"
app:sparkbutton_inActiveImage="@drawable/inactive_image"
app:sparkbutton_primaryColor="@color/primaryColor"
app:sparkbutton_secondaryColor="@color/secondaryColor"

Java

SparkButton button = new SparkButtonBuilder(context)
						.setActiveImage(R.drawable.active_image)
						.setInActiveImage(R.drawable.inactive_image)
						.setPrimaryColor(ContextCompat.getColor(context, R.color.primary_color))
						.setSecondaryColor(ContextCompat.getColor(context, R.color.secondary_color))
						.build();

Animation Speed

You can specify the fraction by which the animation speed should increase/decrease.

XML

app:sparkbutton_animationSpeed="1.5"

Java

sparkbutton.setAnimationSpeed(1.5f);

Button State

If you are using the SparkButton as a switch, you can check/uncheck the button

sparkButton.setChecked(true);

Event Listener

Simply call setEventListener to listen click events.

sparkButton.setEventListener(new SparkEventListener(){
		@Override
		void onEvent(ImageView button, boolean buttonState) {
			if (buttonState) {
				// Button is active
			} else {
				// Button is inactive
			}
		}
});

Play Animation

If you want to play animation regardless of click event execute following function:

sparkButton.playAnimation();

Inspiration

SparkButton is fork of SparkButton by @varunest. It is mainly intended for use in Tusky.
