Item: Animation

When use

TimoMenu.addRow(ItemAnimation itemAnimation, List<TimoItemViewParameter> timoItemViewParameters)

or

TimoMenu.Builder.addRow(ItemAnimation itemAnimation, List<TimoItemViewParameter> timoItemViewParameters)

You need to pass an itemAnimation parameter, it define a base class that allows you to customize the opening animation of the item.

public abstract class ItemAnimation {
    /**
     * Get the animation when the menu is showing.
     *
     * @param itemView The item view.
     * @param positionOfVisibleViews The position in all visible views of the row.
     * @return The animation that executed when the item view is displayed.
     * */
    public abstract Animation getAnimation(TimoItemView itemView, int positionOfVisibleViews);

    /**
     *  Get the animator when the menu is showing.
     *
     * @param itemView The item view.
     * @param positionOfVisibleViews The position in all visible views of the row.
     * @return The animation that executed when the item view is displayed.
     * */
    public abstract Animator getAnimator(TimoItemView itemView, int positionOfVisibleViews);
}

In this base class, you can specify whether to use Animation or Animator.

I have defined 8 animations in this library including reference daimajia/AndroidViewAnimations.

1. FlipItemAnimation
2. ScaleItemAnimation
3. BombItemAnimation
4. StandUpItemAnimation
5. BounceItemAnimation
6. BounceInDownItemAnimation
7. BounceInUpItemAnimation
8. RotateItemAnimation

You can refer to the below picture:

Note

About the parameter 'positionOfVisibleViews', let's look at the below picture

In the row of menu, there are 6 items, but only 4 are visible, item2, item3, item4, item5.

So the position of visible views representative:

• item2 : position = 0
• item3 : position = 1
• item4 : position = 2
• item5 : position = 3
