private ViewGroup.LayoutParams generateDefaultLayoutParams(@NonNull ViewGroup parent) {

     * This whole method is a hack! To generate layout params, since no other way exists.
     * Refer :
    if (null == sParser) {
      synchronized (ViewTypeParser.class) {
        if (null == sParser) {

    return parent.generateLayoutParams(sParser);

    * Show this button at the specific location. If this button isn't attached to any parent view yet,
    * it will be add to activity's root view. If not, it will just update the location.
    * @param parent The parent view. Should be {@link FrameLayout} or {@link RelativeLayout}
    * @param x The x value of anchor point.
    * @param y The y value of anchor point.
    * @param gravity The gravity apply with this button.
    * @see Gravity
