Animate a view in a circle in Android

Move ImageView around the circle with animation

In this article I have created a method which will move ImageView with animation in a circle.

In this method I have used.

1. Path
2. RectF
3. PathMeasure
4. ValueAnimator for animation
5. ImageView

You can take any view instead of ImageView, it depends on your requirements.

public void moveImageInCircle(){
     
    Path p = new Path();

    RectF circle = new RectF(0, 0, 400f, 400f);

    p.arcTo(circle, 0, 180);
    p.arcTo(circle, 180, 180);

    final PathMeasure pm = new PathMeasure(p, false);


    ValueAnimator animator = ValueAnimator.ofFloat(0, pm.getLength());

    final float[] pos = new float[2];
    animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {

            float v = (float) animation.getAnimatedValue();


            pm.getPosTan(v, pos, null);
            
            imageView.setTranslationX(pos[0]);
            imageView.setTranslationY(pos[1]);
        }
    });

    animator.setDuration(3000);
    animator.setRepeatMode(ValueAnimator.RESTART);
    animator.setRepeatCount(ValueAnimator.INFINITE);
    animator.setInterpolator(new LinearInterpolator());
    animator.start();
}
