##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();

##Advanced

  • There can be a situation when you don't want the button to scale download when pressed or consume touch. You can avoid this by calling the following function :

    sparkButton.pressOnTouch(false);
  • If you are using SparkButton between layout hierarchy, it can result in animation getting cropped. To avoid this cropping of the animation, set clipChildren and clipToPadding XML attribute of all the parent views to false.

  • You can view examples of few custom buttons in the sample app.
