Animation is the process of creating motion and shape change. Animation in android is possible from many ways.
Tween Animation
Tween Animation takes some parameters such as startValue , endValue, size , time duration , rotation angle e.t.c and perform the required animation on that object. It can be applied to any type of object. So in order to use this , android has provided us a class called Animation.
Animation animation = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.myanimation);| Method | Description |
|---|---|
| start() | This method starts the animation |
| setDuration(long duration) | This method sets the duration of an animation |
| getDuration() | This method gets the duration which is set by above method |
| end() | This method ends the animation |
| cancel() | This method cancels the animation |
Property animation
An animation defined in XML that modifies properties of the target object, such as background color or alpha value, over a set amount of time.

<set android:ordering="sequentially">
<set>
<objectAnimator
android:propertyName="x"
android:duration="500"
android:valueTo="400"
android:valueType="intType"/>
<objectAnimator
android:propertyName="y"
android:duration="500"
android:valueTo="300"
android:valueType="intType"/>
</set>
<objectAnimator
android:propertyName="alpha"
android:duration="500"
android:valueTo="1f"/>
</set>A container that holds other animation elements (objectAnimator, valueAnimator, or other <set> elements). Represents an AnimatorSet.
You can specify nested <set> tags to further group animations together. Each can define its own ordering attribute.
