Example 1
/**
 * Creates an animator that can be used for x and/or y translations. When interrupted,
 * it sets a tag to keep track of the position so that it may be continued from position.
 *
 * @param view         The view being moved. This may be in the overlay for onDisappear.
 * @param values       The values containing the view in the view hierarchy.
 * @param viewPosX     The x screen coordinate of view
 * @param viewPosY     The y screen coordinate of view
 * @param startX       The start translation x of view
 * @param startY       The start translation y of view
 * @param endX         The end translation x of view
 * @param endY         The end translation y of view
 * @param interpolator The interpolator to use with this animator.
 * @return An animator that moves from (startX, startY) to (endX, endY) unless there was
 * a previous interruption, in which case it moves from the current position to (endX, endY).
