I wonder how I should create a pulse effect using nine olad androids framework animation.

To understand better lets say you have an ImageView and want to have a \"pulse\

Answer 1

heart_pulse.xml put heart_pulse.xml in res/anim folder Add android:interpolator

then use in your activity like below

ImageView imageView =(ImageView)findViewById(R.id.imageView);
Animation pulse = AnimationUtils.loadAnimation(this, R.anim.heart_pulse);
imageView.startAnimation(pulse);
