Android: interpolator specifies an animation plug-in.

There are three types of animation inserts:

1. Accelerate_decelerate_interpolator acceleration-Deceleration animation inserter
2. Accelerate_interpolator acceleration-animation insertor
3. Decelerate_interpolator deceleration-animation insertor

Android: fromXScale attribute is the scaling size on the X coordinate when the animation starts
The toXScale attribute is the scaling size on the X coordinate when the animation ends.

The fromYScale attribute is the scaling size on the Y coordinate at the start of the animation.
The toYScale attribute is the scaling size on the Y coordinate when the animation ends.

Note:
The preceding four property values

0.0 indicates shrinking to none
1.0 indicates normal scaling-free
A value smaller than 1.0 indicates contraction.
Value greater than 1.0 indicates Amplification

The ready TX attribute is the starting position of the animation relative to the X coordinate of the object.
The ready ty attribute is the starting position of the animation relative to the Y coordinate of the object.

Note:
The preceding two attribute values are from 0% to 100%.
50% indicates the point position on the X or Y coordinate of the object.

Long integer value:
The duration attribute is the animation duration.
Description: The time is in milliseconds.

Boolean value:
FillAfter attribute whenSetTrue. The animation is convertedApplication
