TranslateAnimation class: Position change animation class (similar to the tab switching effect)

TranslateAnimation class: Position change animation class (similar to the tab switching effect)

The TranslateAnimation class is an animated class for Android system location changes. It is used to control the location changes of View objects. This class inherits from the Animation class. Many methods in the TranslateAnimation class are consistent with the Animation class. The most common method in this class is the TranslateAnimation constructor.

[Basic syntax] public TranslateAnimation (float fromXDelta, float toXDelta, float fromYDelta, float toYDelta)

Parameter description

FromXDelta: X coordinate of the starting point of the position change.

ToXDelta: X coordinate of the ending point of the location change.

FromYDelta: Y coordinate of the start point of the position change.

ToYDelta: Y coordinate of the end point of the location change.

Note: The initial coordinates are critical, especially when the animation is continuously switched. The subsequent animations take the initial coordinates as the reference system. The coordinate origin is critical.

Multiple location effects similar to tab switching can be encapsulated into the properties selected by radio, making it easier to use
